astro-ph/0207226 Detecting Radio Emission from Cosmic Ray Air Showers and Neutrinos with a Digital Radio Telescope
Author: Heino Falcke, Peter Gorham
Comments: Astropart. Phys., in press, LaTex (elsart.cls included), 29 pages, 4 figures, also available at http://www.mpifr-bonn.mpg.de/staff/hfalcke/publications.html#lofarpaper

Oh uzh eti kosmicheskie luchi sverhvysokih energii! Vse hotyat ih registrirovat'. Pri etom metodiki mogut byt' raznymi. Naprimer, mozhno pytat'sya nablyudat' radioizluchenie.

Ideya v izluchenii, sozdavaemom elektron-pozitronnymi parami, dvizhushimisya v zemnom magnitnom pole.

Dlya takih nablyudenii nuzhny novye instrumenty. Takim budet teleskop LOFAR (Low-Frequency Array), rabotayushii na 10-200 MHz. Uzhe sushestvuet prototip: LOPES. V otdalennom budushem poyavit'sya kilometrovaya reshetka (Square-Kilometer-Array SKA). Eto eshe bolee moshnyi instrument.

obzor, missiya astro-ph/0210554 Blizkoe mikrolinzirovanie i ego vliyanie na nablyudenie prohozhdenii po disku zvezd v eksperimente Kepler (Near-Field Microlensing and Its Effects on Stellar Transit Observations by Kepler)
Authors: Kailash C. Sahu (Space Telescope Science Institute) and Ronald L. Gilliland (Space Telescope Science Institute)
Commets: 34 pages, including 15 figures, Accepted for publication in Astrophysical Journal

Osnovnaya cel' kosmicheskogo eksperimenta "Kepler" - poisk planet u blizhaishih zvezd po izmeneniyu ih bleska v hode prohozhdeniya planety po disku zvezdy. NASA predpolagaet issledovat' bolee 100,000 zvezd spektral'nyh klassov F, G i K za 4 goda nablyudenii. Kepler smozhet poluchat' fotometriyu zvezd s tochnost'yu 90 mikro-zvezdnyh velichin (9x10-5zv.velichiny) pri 15 minutnoi ekspozicii.

Effekt mikrolinzirovaniya deistvuet v storonu protivopolozhnuyu zatmeniyu (prohozhdeniyu), t.e. ne oslablyaet, a usilivaet blesk zvezdy. No obychno dlya planet etim effektom mozhno prenebrech' - iz-za togo, chto razmer zvezdy velik i usilivaetsya (linziruetsya) izluchenie tol'ko ot nebol'shoi chasti ee poverhnosti. Drugoi prichinoi yavlyaetsya to, chto sami planety perekryvayut chast' potoka usilivaemogo izlucheniya, esli oni raspolozheny blizko k zvezde. Odnako, esli zvezda v sisteme kompaktna (v pervuyu ochered' ei mozhet byt' goryachii belyi karlik) i/ili planeta raspolozhena dostatochno daleko, to effekt mikrolinzirovaniya mozhet okazat'sya sushestvennym i dazhe perekryt' ospablenie iz-za prohozhdeniya.

Eti i blizkie k nim voprosy dostatochno podrobno i neslozhno rassmotreny v dannom obzore.

Nesmotrya na to, chto seichas v kosmose nahodyatsya tri otlichnye observatorii, rabotayushie v zhestkom diapazone, nam nuzhna eshe odna - dlya obzora. Chandra i N'yuton - prekrasnye instrumenty dlya izucheniya otdel'nyh istochnikov i glubokih polei. No neobhodimy i obzory novogo pokoleniya. EXIST kak raz dlya etogo i prednaznachen.

Sputnik budet davat' obzor neba kazhdye 95 minut (period orbity) v diapazone 10-600 kEv. Uglovoe razreshenie - neskol'ko uglovyh minut. Stoimost' proekta 380 mln.doll.


astro-ph/0212027 Optimizaciya GAIA: kak my vstrechaem nauchnyi vyzov? (Optimising GAIA: How do we meet the science challenge?)
Authors: Gerry Gilmore
Commets: 11 pages, Proceedings of the Monte Rosa Conference "GAIA Spectrosc Science and Technology ", U.Munari ed., ASP Conf. Series, in press

Ne vse vyskazyvayut odnoznachnyi optimizm po povodu sovremennogo dizaina sputnika GAIA. Gerri Gilmor daet skepticheskii analiz vozmozhnostei sputnika, pokazyvaya, kakih iz postavlennyh celei vozmozhno ne udast'sya dostignut'. On predlagaet optimizirovat' nekotorye iz priborov na sputnike (eto eshe ne pozdno!), chtoby missiya byla bolee produktivnoi.

missiya astro-ph/0212067 SPOrt: eksperiment, prizvannyi izmerit' polyarizaciyu reliktovogo izlucheniya na bl'shih masshtabah (SPOrt: an Experiment Aimed at Measuring the Large Scale Cosmic Microwave Background Polarization)
Authors: E. Carretti et al.
Commets: 9 pages, 5 figures, conference proceeding, to appear in "Polarimetry in Astronomy", SPIE Symposium on 'Astronomical Telescopes and Instrumentation', Waikoloa, August 22-28 2002

Chasto sprashivayut, zachem (v smysle nauki) nuzhna MKS. Otvet: na MKS budet mnogo astrofizicheskih missii, i eto namnogo deshevle (konechno, posle togo, kak uzhe postroili stanciyu), chem zapuskat' otdel'nye sputniki. Sredi etih proektov i rossiisko-ital'yanskii SPOrt.

Napomnyu, chto u Rossii uzhe byl svoi sputnik, izmeryavshii reliktovyi fon. Eto apparat "Relikt" (sm. opisanie eksperimenta i rezul'tatov v nedavnei knige Sazhina). Teper' planiruetsya primenit' nakoplennyi opyt v sovmestnom eksperimente po izmereniyu polyarizacii.

Commets: 5 pages, no figure, Latex file Journal-ref: Int.J.Mod.Phys. D11 (2002) 1061-1065

Davno izvestna ideya ispol'zovat' pul'sary dlya registracii sverhnizkochastotnyh gravitacionnyh voln s periodami ot 1 do 100 let. Teper' dlya etoi zadachi predlagaetsya postroit' special'nyi 50 m radioteleskop, kotoryi budet regulyarno izmeryat' taiming 10 naibolee stabil'nyh millisekundnyh pul'sarov.

Commets: SPIE Proceedings, Future Research Direction and Visions for Astronomy, 8 pages

Vpervye poyavlyaetsya vozmozhnost' otkryvat' i zatem issledovat' vnesolnechnye planety podobnye Zemle. Eto budet delat' apparat TPF (Terrestrial Planet Finder - iskatel' zemlepodobnyh planet). NASA planiruet zapustit' etot apparat primerno v 2015 g. Podobnuyu cel' presleduet proekt Darvin, razrabatyvaemyi Evropeiskim kosmicheskim agentstvom. Na etih apparatah budet vestis' spektral'nyi poisk tak nazyvaemyh "biomarkerov" - takih kak O2, O3, H2O, CO i CH4 - v atmosferah takih planet. Nalichie etih gazov ukazyvaet na prisutstvie zhizni na planete ili, po krainei mere, na vozmozhnost' ee kolonizacii. V etom eksperimente takzhe budut vyyasnyat'sya takie parametry planet, kak ih radius, temperatura poverhnosti, nalichie l'da na poverhnosti, period vrasheniya, sushestvovanie sezonov.

Nalichie rastitel'nosti podobnoi zemnoi mozhet byt' vyyavleno po tak nazyvaemomu "krasnomu krayu" (red edge) primerno na 700 nm. Eta detal' otlichaetsya ot vseh izvestnyh atomnyh i molekulyarnyh spektral'nyh osobennostei. Bolee podrobno etot vopros rassmatrivaetsya v stat'e astro-ph/0212550

Commets: 12 pages, 10 figures, Astronomical Telescopes and Instrumentation (Polaimetry in Astronomy) Hawaii August 2002 SPIE Meeting

Opisan eksperiment BaR-SPOrt. Pro SPOrt my uzhe rasskazyvali. Eto ital'yansko-rossiiskii proekt dlya MKS po issledovaniyu reliktovogo izlucheniya. BaR-SPOrt - eto balonnyi eksperiment, na kotorom ustanovlena analogichnaya apparatura.

Stat'ya korotkaya, no pri etom dovol'no tehnicheskaya. Kogda sobirayutsya puskat' "sharik" neponyatno. Odnako, priyatno, chto delo dvizhetsya.

Authors: J. Braga et al.
Commets: 6 pages, 1 table, 3 figures, presented at 2002 COSPAR meeting in Houston. Submitted to Adv. Space Res

Kogda-to sovetskii korrespondent sprosil Pele, kogda, po ego mneniyu, SSSR budet chempionom mira po futbolu. Pele otvetil: "Kogda Braziliya budet chempionom mira po hokkeyu". Ostroumno, no erunda, vse-taki my byli pervymi chempionami Evropy .... Odnako, vot Braziliya sobiraetsya rentgenovskii sputnik delat' (predpolagaemyi zapusk 2007/8). Pora by i nam hot' Spektr-RG zapustit'. A to stydno...

astro-ph/0303421 Issledovatel' relyativistskoi astrofiziki (Relativistic Astrophysics Explorer)
Authors: P. Kaaret
Commets: to appear in Advances in Space Research, 6 pages with one color figure (low-res)

V stat'e opisyvaetsya proekt novogo sputnika. Plany svyazany s ochen' uspeshnoi missiei Rossi X-Ray Timing Explorer (RXTE), izyuminka kotoroi zaklyuchalas' v vysokom vremennom razreshenii. Schitaetsya, chto dlya sushestvennogo progressa novyi instrument dolzhen prevoshodit' staryi na poryadok (rech' idet o progresse v smysle "nepredskazuemy" t.n. serendipicheskih otkrytii). Tak ono i est' v dannom sluchae.

Osnovnye prognoziruemye zadachi sputnika takovy: izuchenie kvaziperiodicheskih oscillyacii (osobenno bystryh oscillyacii ot kandidatov v chernye dyry) i millisekundnye oscillyacii v rentgenovskih vspleskah (barsterah). Odnako yasno, chto etim delo ne ogranichitsya.

Avtor setuet, chto v proshedshem desyatiletii bylo vsego dve amerikanskie rentgenovskie missii (Chandra i RXTE), a potomu vazhno delat' eshe i eshe.... Budem nadeyat'sya, chto proekt poluchit podderzhku.
