Comments: 12 pages, a White paper submitted to ESA

Avtory (spravedlivo) polagayut, chto poluchenie pryamyh izobrazhenii ekzoplanet - eto kraine vazhnaya zadacha. Konechno, takaya mysl' ne nova, i lyudi uzhe zanimayutsya razrabotkoi moshnyh kosmicheskih proektov, kotorye pozvolyat "v promyshlennyh masshtabah" poluchat' takie dannye. No do osushestvleniya krupnyh proektov poka dalekovato. A potomu avtory zashishayut ideyu o dostatochno bystrom sozdanii kosmicheskogo teleskopa-koronografa 1-2-metrovogo diametra dlya polucheniya pryamyh izobrazhenii. V chastnosti, avtory predlagayut udelit' bol'she vnimaniya super-zemlyam (s massoi raz v desyat' bol'she zemnoi), t.k. oni potencial'no obitaemy, a iskat' ih i issledovat' gorazdo proshe.

Po vsei vidimosti, naibolee realistichnye vozmozhnosti "uvidet'" sledy inflyacii svyazany s pervichnymi gravitacionnymi volnami. Vopros ih pryamoi registracii, skoree vsego, delo budushego. No mozhno popytat'sya uvidet' "otpechatok" ih sushestvovaniya v mikrovolnovom fone.

V ramkah proekta "Za Einshteinom" (Beyond Eistein) planiruetsya zapusk sputnika, kotoryi dolzhen budet razglyadet' V-mody polyarizacii reliktovogo izlucheniya.

Odnoi iz zadach dlya sistemy radioteleskopov SKA budet poisk novyh pul'sarov. Prichem, rech' idet ne tol'ko i ne stol'ko o prostom uvelichenii chisla otkrytyh ob'ektov, ili ob obnaruzhenii pul'sarov v blizkih galaktikah, a ob otkrytii ekzoticheskih sistem. Naprimer, mozhno leleyat' mechtu o nobelevskoi premii za obnaruzhenie pary pul'sar plyus chernaya dyra, vidimoi pochti s rebra (t.e., chtoby pul'sar "prosvechival" okrestnosti chernoi dyry).

V stat'e detal'no razbiraetsya, kak SKA smozhet issledovat' radiopul'sary. Zamechu, odnako, chto okonchatel'nyi dizain sistemy eshe ne vybran, poetomu ocenki mogut slegka popolzti. Po suti, prodolzhaetsya bor'ba mezhdu pul'sarnoi i vnegalakticheskoi programmami, kotorye trebuyut raznogo dizaina sistemy. Sushestvenno, chto kogda SKA nachnet rabotu, to dlya issledovanii pul'sarov ogranicheniem mozhet stat' ob'em dannyh. Nuzhny budut ochen' moshnye vychislitel'nye sredstva dlya obrabotki nablyudenii. Po suti, planiruya programmy, uchenye ekstrapoliruyut rost vychislitel'noi moshnosti komp'yuterov i stoimosti hraneniya dannyh. Ispol'zuemye ocenki: v 2015 godu 10 Pflop budut stoit' 100 millionov dollarov. T.e., bez progressa v etoi oblasti spravitsya s budushimi nablyudeniyami budet neprosto.

Ozhidaetsya, chto SKA uvidit bolee 20 000 pul'sarov (iz nih 6000 - millisekundnye). Vsego v Galaktike okolo 30 000 normal'nyh pul'sarov i stol'ko zhe milisekundnyh, ch'i signaly popadayut na Zemlyu (napomnyu, chto izluchenie pul'sara skoncentrirovano v dostatochno uzkom konuse). Razumeetsya, nado uchest', chto iz dannoi tochki Zemli ne vse nebo dostupno dlya nablyudenii. Kstati, eti ocenki pozvolyayut rasschityvat' na desyatok sistem pul'sar plyus chernaya dyra, tak chto odna iz nih mozhet imet' ploskost' orbity vblizi lucha zreniya. Optimizaciya sistemy dlya pul'sarnyh issledovanii pozvolit neskol'ko uvelichit' eto chislo, no na moi vzglyad, maloveroyatno, chto eto budet sdelano v usherb vnegalakticheskim issledovaniyam.

Comments: 7 pages, 5 figures, invited talk at the ICSO conference, Toulouse, oct. 2008

V rentgenovskom diapazone dlya postroeniya izobrazhenii ispol'zuyut zerkala kosogo padeniya. Poetomu pri nebol'shoi real'noi sobirayushei ploshadi teleskopy poluchayutsya dlinnymi. Seichas pri sozdanii takih instrumentom kak XMM-Newton i Chandra my uzhe podoshli k predelu: ne vlezaet pod obtekatel' (ili v gruzovoi otsek Shattla). Poetomu, chtoby sozdat' instrumenty sleduyushego pokoleniya pridetsya raznosit' ob'ektiv i detektor (primerno kak v "vozdushnyh teleskopah" 18 veka).

Bol'shie missii, osnovannye na raznesennyh konfiguriruemyh p polete apparatah, poka tol'ko planiruyutsya. No uzhe idut raboty nad bolee skromnymi missiyami, postroennymi po takoi tehnologii. Amerikancy planiruyut sdelat' proekt NuSTAR. Tam, pravda, dve chasti teleskopa vse-taki budut soedineny legkoi fermoi. A vot evropeiskii Simbol-X budet deistvitel'no sostoyat' iz dvuh sovershenno otdel'nyh otsekov. Opisanie proekta mozhno naiti v etom nebol'shom materiale.

Dva sputnika budut letat' na rasstoyanii 20 metrov drug ot druga. Tochnost' otnositel'noi orientacii sputnikov budet poryadka neskol'kih millimetrov v napravlenii perpendikulyarnom soedinyayushei sputniki osi, i neskol'ko santimetrov - vdol' osi.

Vazhno podcherknut', chto i Simbol-X, i NuStar?, budut ne prosto tehnologicheskimi prototipami, a real'no rabotayushimi ochen' horoshimi astronomicheskimi instrumentami. Drugoe delo, chto krome resheniya astrofizicheskih zadach oni eshe dolzhny prolozhit' put' dlya krupnyh proektov sleduyushego pokoleniya.

Chasticy kosmicheskih luchei mogut imet' ochen' bol'shie energii. Proishozhdenie takih chastic poka ostaetsya zagadkoi. Ne v poslednyuyu ochered' eto svyazano s tem, chto takih chastic prosto malo: odna v god na ploshad' v neskol'ko soten kvadratnyh kilometrov. Dlya nablyudenii takih chastic stroyat gigantskie kompleksy. Takie kak observatoriya imeni P'era Ozhe i Telescope Array. No vse ravno statistika nabiraetsya medlenno.

Napomnyu, chto chasticy ne registriruyutsya neposredstvenno. Vletaya v atmosferu na vysote v neskol'ko desyatkov kilometrov, chasticy vzaimodeistvuyut s molekulami zemnoi atmosfery. V itoge voznikaet potok vtorichnyh chastic i vspyshka v opticheskom diapazone. Nazemnye detektory registriruyut i to, i drugoe.

Uzhe davno vyskazyvalas' ideya, chto bylo by neploho nablyudat' iz kosmosa srazu vsyu atmosferu vidimoi chasti Zemli. Mozhno otslezhivat' vspyshki, svyazannye s vletom energichnyh chastic. Togda effektivno proishodit sbor informacii s ploshadi v desyatki millionov kvadratnyh kilometrov. Dlya etogo nado zapustit' sootvetstvuyushii detektor. Uzhe mnogo let idut rzrabotki takih proektov.

Napomnyu, chto poka samaya legkaya planeta (s massoi poryadka 5 zemnyh) byla obnaruzhena metodom mikrolinzirovaniya. Zdes', pravda, nuzhno sdelat' odin kommentarii o metode. My govorim o mikrolinzirovanii, kogda odna zvezda linziruetsya drugoi (ili analogichnym ob'ektom: belym karlikom, neitronnoi zvezdoi, chernoi dyroi, burym karlikom i tp.). Sootvetstvenno, uchenye sledyat odnovremenno za millionami zvezd-istochnikov. Esli pryamo pered odnoi iz nih proletit zvezda-linza, to my uvidim vozrastanie bleska zvezdy-istochnika. Esli u linzy est' sputnik (planeta), to na krivoi bleska budet harakternyi pichok. Analiziruya krivuyu bleska mozhno poluchit' raspredelenie veroyatnostei dlya parametrov linzy (i ee sputnika, esli on est'). No kraine redko udaetsya obnaruzhit' samu linzu! Tak chto nesmotrya na svoyu silu metod mikrolinzirovaniya, v smysle poiska ekzoplanet, imeet i sushestvennye nedostatki: i zvezda-linza i ee sputnik chashe vsego ne nablyudayutsya posle sobytiya mikrolinzirovaniya, a parametry ne opredelyayutsya dostatochno dostoverno. Tem ne menee.....

Tem ne menee, v obozrimom budushem tol'ko etot metod mozhet pozvolit' nabrat' bol'shuyu statistiku po legkim planetam. A dlya etogo nado mnogo nablyudat'.

Konechno, "risoval'shik" - eto ne vpolne adekvatnyi perevod slova "imager", no chto delat'!?! Ideya sostoit v tom, chto sovremennye tehnologie pozvolyayut sozdat' gamma-detektor, kotoryi budet dostatochno horosho stroit' izobrazheniya v gamma-dipazone. T.e., eto budet v samom dele gamma-teleskop, rabotayushii napryamuyu s gamma-fotonami. Seichas izobrazheniya v gamma-diapazone stroyatsya primitivno po dannym o prohozhdenii fotona cherez stopku detektiruyushih plastin (na sputnikah), ili zhe nablyudayutsya opticheskie kvanty, porozhdennye vzaimodeistviem gamma-kvantov s atmosferoi (na ustanovkah tipa H.E.S.S.).

Comments: 10 pages, in press ChJAA

Konechno, hochetsya zaregistrirovat' gravitacionnye volny kak mozhno neposredstvennee. Dlya etogo i stroyat lazernye interferometry i tverdotel'nye ustanovki. Odnako nablyudeniya radiopul'sarov pozvolyayut poluchat' dannye o gravitacionnyh volnah pust' i ne stol' neposredstvennym, zato bolee deshevym putem. Vse horosho znayut o tom, chto dvoinye radiopul'sary ispytyvayut izmeneniya orbit za schet izlucheniya gravitacionnyh voln. Est' i drugie effekty, svyazannye s nablyudeniem etih ob'ektov, pozvolyayushie poluchat' informaciyu o gravitacionnyh volnah.

Vazhnym dostoinstvom millisekundnyh radiopul'sarov yavlyaetsya porazitel'naya ustoichivost' ih periodov. Ona sravnima s luchshimi zemnymi atomnymi chasami. Po suti, nablyudeniya neskol'kih takih pul'sarov mogut dat' standart chastoty prevoshodyashii atomnye! Etu osobennost' mozhno ispol'zovat' dlya kosvennogo nablyudeniya garvitacionnyh voln.

Gravitacionnye volny vliyayut na nablyudaemye periody pul'sarov. Imenno na nablyudaemye, t.k. rech' idet ob effekte, svyazannym s prohozhdeniem volny cherez nas. Iz-za prohozhdeniya volny period pul'sara budet kazat'sya nam to koroche, to dlinnee. Ideya takogo obnaruzheniya gravitacionnyh voln byla vpervye vyskazana M.V. Sazhinym v 1978 g. Issleduya odin ob'ekt mozhno dat' verhnii predel na fon gravitacionnyh voln (vokrug nas) v opredelennom diapazone chastot. Prichem, pul'sarnye dannye chuvstvitel'ny k ochen' bol'shim periodam - poryadka vremeni nablyudeniya, t.e. neskol'ko let (sootvetstvenno, chastoty gravvoln ischislyayutsya v dannom sluchae nanogercami). Nablyudeniya za neskol'kimi pul'sarami pozvolyaet (tochnee mozhet pozvolit') zaregistrirovat' etot gravitacionno-volnovoi fon.

Sobstvenno, "pul'sarnaya vremennaya reshetka" (Pulsar Timing Array) eto ne novyi pribor. Sami pul'sary i obrazuyut "reshetku" ili "set'". Nablyudeniya zhe planiruetsya provodit' na uzhe horosho izvestnom 64-metrovom radioteleskope. Hotya, elektronnaya nachinka i programmnoe obespechenie dolzhny byt' dorabotany, chtoby vyiti na neobhodimuyu chuvstvitel'nost'. Takaya neobhodimost' byla prodemonstrirovana v techenie pervogo goda nablyudenii.

Krome togo trebuetsya (i eto vozmozhno) obespechit' bolee tochnoe (po-sravneniyu s Pionerami) otslezhivanie skorosti i polozheniya apparata. Dlya drugih nauchnyh zadach takaya tochnost' nesushestvenna, no bylo by neploho ee zalozhit' v konstrukciyu, chtoby nakonec razobrat'sya s etoi anomaliei. Hotya ... dazhe esli proekt budet odobren, zhdat' pridetsya dolgo.
