Commets: 7 pages
Est' li na samom dele chernye dyry ili zhe vse-taki mozhno pridumat' kakie-to konfiguracii, kotorye dlya nas byli by neotlichimy ot chernyh dyr? Eto ne pustoi vopros. Po etomu povodu byla podrobnaya stat'ya Abramovicha i dr. astro-ph/0207270 s "govoryashim" nazvaniem "No observational proof of the black-hole event-horizon".
Heil v svoei stat'e pokazyvaet, chto fakt akkrecii nakladyvaet dopolnitel'nye sil'nye ogranicheniya na uhishreniya "ostavit' mir bez chernyh dyr". V pervuyu ochered' rech' idet o krasnom smeshenii, sootvetstvuyushem poverhnosti takih staticheskih konfiguracii. Ono okazyvaetsya vpolne nablyudaemym, osobenno dlya sverhmassivnyh chernyh dyr. Koli my ego ne vidim, to stalo byt' vse-taki dyry est' (po-krainei mere sverhmassivnye).

Vnesolnesnaya planeta HD 80606b iseet ochen' strannye orbital'nye parametry: poluos' a=0.47AU (eto normal'no) i ekscentrisitet e=0.93, t.e. v periaste ona priblizhaetsya k zvezde primerno na 7R_sun. Kak mogla vozniknut' takaya situaciya? Avtory predlagayut sleduyushii scenarii. V shirokoi dvoinoi sisteme s poluos' ~1000AU vokrug odnoi iz zvezd po orbite s a~5AU obrashalas' planeta. Ekcentrisitet ee orbity byl nebol'shim, no ee ploskost' byla pochti perpendikulyarna ploskosti orbity dvoinoi sistemy. Iz-za vliyaniya vtorogo komponenta (i voobshe v kvadrupol'nom gravitacionnom pole podobnom polyu splyusnutogo ellipsoida) ekscentrisitet orbity planety nachinaet bystro menyat'sya (ot malogo do pochti edinicy). Etot process nazyvayut "effektom Kozai". No esli planeta podhodit ochen' bystro k svoei zvezde, to vklyuchayutsya prilivnye effekty i ona nachinaet priblizhat'sya k nei.
Ne yasno imeet li eta shema otnoshenie k HD 80606b, tak kak vtoroi komponent u etoi zvezdy poka na obnaruzhen.

Vnesolnesnaya planeta HD 80606b iseet ochen' strannye orbital'nye parametry: poluos' a=0.47AU (eto normal'no) i ekscentrisitet e=0.93, t.e. v periaste ona priblizhaetsya k zvezde primerno na 7R_sun. Kak mogla vozniknut' takaya situaciya? Avtory predlagayut sleduyushii scenarii. V shirokoi dvoinoi sisteme s poluos' ~1000AU vokrug odnoi iz zvezd po orbite s a~5AU obrashalas' planeta. Ekcentrisitet ee orbity byl nebol'shim, no ee ploskost' byla pochti perpendikulyarna ploskosti orbity dvoinoi sistemy. Iz-za vliyaniya vtorogo komponenta (i voobshe v kvadrupol'nom gravitacionnom pole podobnom polyu splyusnutogo ellipsoida) ekscentrisitet orbity planety nachinaet bystro menyat'sya (ot malogo do pochti edinicy). Etot process nazyvayut "effektom Kozai". No esli planeta podhodit ochen' bystro k svoei zvezde, to vklyuchayutsya prilivnye effekty i ona nachinaet priblizhat'sya k nei.
Ne yasno imeet li eta shema otnoshenie k HD 80606b, tak kak vtoroi komponent u etoi zvezdy poka na obnaruzhen.

Kak mogla vozniknut' takaya situaciya? Avtory predlagayut sleduyushii scenarii. V shirokoi dvoinoi sisteme s poluos' ~1000AU vokrug odnoi iz zvezd po orbite s a~5AU obrashalas' planeta. Ekcentrisitet ee orbity byl nebol'shim, no ee ploskost' byla pochti perpendikulyarna ploskosti orbity dvoinoi sistemy. Iz-za vliyaniya vtorogo komponenta (i voobshe v kvadrupol'nom gravitacionnom pole podobnom polyu splyusnutogo ellipsoida) ekscentrisitet orbity planety nachinaet bystro menyat'sya (ot malogo do pochti edinicy).

Kak mogla vozniknut' takaya situaciya? Avtory predlagayut sleduyushii scenarii. V shirokoi dvoinoi sisteme s poluos' ~1000AU vokrug odnoi iz zvezd po orbite s a~5AU obrashalas' planeta. Ekcentrisitet ee orbity byl nebol'shim, no ee ploskost' byla pochti perpendikulyarna ploskosti orbity dvoinoi sistemy.

Chto by tam ni govorili nedobrozhelateli, no amerikancy delayut ochen' mnogo, chtoby drugie mogli pol'zovat'sya ih zhe (amerikancev) dannymi s amerikanskih zhe (i ne tol'ko) sputnikov. XAssist - primer takoi sistemy. Ona razrabatyvaetsya v NASA i uzhe blizka k vyhodu na "shirokuyu astronomicheskuyu dorogu" analiza rentgenovskih nablyudenii. Sistema ispytana na dannyh Chandra i ROSAT HRI, chastichno podderzhivayutsya dannye XMM. V osnovnom sistema rasschitana na obrabotku nablyudenii nashei Galaktiki. V stat'e dano ee kratkoe opisanie.

Reshat' zadachi akkrecii neposredstvenno v ramkah OTO dostatochno tyazhelo. Poetomu vmesto iskrivlennogo prostranstva mozhno popytat'sya vvesti psevdo-N'yutonovskii potencial v kotorom dvizhenie chastic opisyvaetsya pravil'no. Eto udaetsya sdelat' dlya Shvarcshil'dovskogo gravitacionnogo polya, kotoroe sushestvuet vokrug nevrashayushihsya neitronnyh zvezd i chernyh dyr. Dlya vrashayushihsya ob'ektov oboitis' odnim potencialom ne udaetsya. Avtor podrobno rassmatrivaet kak edinym obrazom mozhno vvesti takie potencialy i v kakih sluchayah dannyh podhod rabotaet.

My uzhe neodnokratno pisali ob ul'tramoshnyh istochnikah, i obzory mozhno naiti v Arhive (ssylki v nashei baze obzorov). Istochnik IC 342 X-1 yavlyaetsya otnositel'no blizkim (rasstoyanie do galaktiki, v kotoroi on nahoditsya, ocenivaetsya v 4 Mpk, odnako tut est' neopredelennost'). V stat'e rech' idet ob otkrytii obrazovaniya, ochen' pohozhego na ostatok sverhnovoi, okruzhayushii ul'tramoshnyi istochnik. Radius ostatka .... 110 pk! Razumeetsya sleduet razumnoe rassuzhdenie ob obrazovanii chernoi dyry pri vzryve gipernovoi.

Authors: Yoko Funato et al.
Commets: 10 pages, 3 Figures
Poyas Koipera i osnovnoi poyas asteroidov obrazovalis' iz odnogo i togo zhe protoplanetnogo oblaka, no poslednie nablyudeniya trans-Neptunovyh ob'ektov (TNO) pokazali, chto otnositel'no dvoinyh ob'ektov nablyudayutsya sleduyushie sushestvennye razlichiya:

dolya dvoinyh v poyase Koipera na poryadok vyshe;
otnoshenie mass bol'shinstva dvoinyh ob'ektov poyasa Koipera blizko v 1;
orbity dvoinyh ob'ektov v poyase Koipera bolee shirokie i bolee vytyanutye.
Avtory schitayut, chto vnachale populyacii dvoinyh byli odinakovy. No zatem, pri blizkih proletah tret'ih tel, malomassivnye komponenty zamenyalis' bolee massivnymi. V poyase Koipera etot process shel sushestvenno intensivnee, t.k. tam men'she prilivnoe vozdeistvie Solnca.
