    V edinyh modelyah razlichnye tipy AYaG ob'yasnyayutsya v ramkah akkrecii na sverhmassivnuyu chernuyu dyry. Razlichie proyavlenii opredelyaetsya raznoi massoi dyry, raznym tempom akkrecii, raznoi orientaciei dzheta po otnosheniyu k nablyudatelyu i raznymi svoistvami sredy vblizi dyry i dzheta (otsyuda vazhnost' ucheta pyli).

    V novoi stat'e v pervuyu ochered' detal'no opisyvaetsya eksperiment i rezul'taty izmerenii. Odnako, est' i razdel "diskussiya", gde "kratko i myagko" obsuzhdaetsya interpretaciya poluchennyh rezul'tatov: t.e. perechislyayutsya vozrazheniya, privodyatsya ssylki na nih i na otvety, a takzhe delaetsya sushestvenno bolee myagkoe utverzhdenie, chto "osnovnoi interpretaciei eksperimenta yavlyaetsya soglasie rezul'tatov s predskazaniyami OTO".

    Esli v centre galaktiki sidit chernaya dyra, to te zvezdy, kotorye mogli byt' ei bystro zahvacheny, uzhe ei poglosheny. Teper' (v kvazistacionarnoi situacii) zahvatyvayutsya zvezdy, ch'i orbity prolegayut ryadom s granicei zahvata (konusa poter') i peresekayut ego iz-za vneshnih vozmushenii. Temp akkrecii (zahvata zvezd) v takoi situacii mal, kak i svetimost' chernoi dyry. Situaciya izmenyaetsya, esli gravitacionnyi potencial vblizi centra galaktiki ne obladaet osevoi simmetriei (naprimer, yavlyaetsya trehosnym) ili/i zvezdy dvizhutsya haoticheskim obrazom (sm. nizhe stat'yu o haoticheskih yavleniyah).

    Vpervye udalos' zaregistrirovat' spektral'nye (absorbcionnye) linii ot zvezdy, vrashayusheisya ochen' blizko ot "nashei" sverhmassivnoi chernoi dyry. Zvezda okazalas' massivnoi (M poryadka 15 mass Solnca). Dovol'no molodoi: ona eshe nahoditsya na glavnoi posledovatel'nosti. Eto paradoksal'nyi rezul'tat, t.k. schitalos', chto tak blizko ot chernoi dyry, gde prilivnye sily ochen' veliki, zvezdy ne obrazuyutsya. krome togo, vremya migracii zvezdy na takuyu orbity (esli ona rodilas' tam, gde prilivy slabee) bol'she vremeni zhizni stol' massivnoi zvezdy.

    Avtory obsuzhdayut razlichnye idei, pozvolyayushie ob'yasnit' takoi fenomen. Naprimer, "reinkarnaciyu" zvezdy posle sliyaniya (dve slivshiesya nebol'shie zvezdy mogut posle sliyaniya vyglyadet' kak massivnyi ob'ekt). Vozmozhny i drugie ob'yasneniya, svyazannye s vysokoi plotnost'yu zvezd v etoi oblasti, a znachit s vysokoi veroyatnost'yu ih vzaimodeistviya.

    Commets: A&A, in press, 13 pages

    Kak izvestno, v nashei galaktike sverhnovye ne nablyudalis' poslednie 400 let. I eto pri tempe vspyshek poryadka odnoi v 30 let! Ob'yasnenie prostoe - vspyhivayut daleko i zakryty pyl'yu. T.e. nesmotrya na potryasayushuyu moshnost' vzryva ego taki mozhno nezametit'. Pohozhaya kartina proishodit i v drugih galaktikah. Pravda, tam my redko vidim galaktiku s rebra, kak v sluchae Mlechnogo Puti, v ploskosti kotorogo my nahodimsya. Tem ne menee v galaktikah s burnym zvezdoobrazovaniem, gde dolzhno byt' mnogo sverhnovyh, mnogo i pyli. Poetomu interesno smotret' v IK diapazone, gde pyl' ne tak meshaet. Avtory predstavlyayut rezul'taty svoih issledovanii. Po nablyudeniyam 46 yarkih IK galaktik na dline volny 2.2 mikrona bylo otkryto 4 sverhnovye. Etot temp vspyshek primerno na poryadok prevoshodit temp opticheski zaregistrirovannyh vspyshek (otmetim, chto oshibki vse-taki veliki, t.k. statistika mala). Prichem, ozhidalos' eshe bol'she vspyshek. Znachit, kakie-to sverhnovye vse-taki "nagluho" zakryty pyl'yu....
