Obnaruzhit' planetu v dvoinoi zvezdnoi sisteme - eto sovsem ne to zhe samoe, chto obnaruzhit' ee okolo odinochnoi zvezdy.

Effekt sostoit vo vzaimodeistvii goryachih elektronov v skopleniyah galaktik s mikrovolnovym fonom. V rezul'tate vzaimodeistviya ot elektronov fotonam peredaetsya energiya. Pole relikovyh fotonov imeet izvestnye harakteristiki. Esli my polagaem, chto stroenie skopleniya nam takzhe izvestno, to po nablyudenii effekta my mozhem opredelit' razmer skopleniya, a sledovatel'no i rasstoyanie do nego. Neodnokratnye popytki opredeleniya postoyannoi Habbla s pomosh'yu etogo metoda privodili k rezul'tatu, sistematicheski men'shemu, chem po drugim indikatoram. V stat'e avtory analiziruyut prichiny etogo rashozhdeniya. Avtory ispol'zuyut usovershenstvovannuyu model', v kotoroi uchteny razlichnye detali svyazannye s formoi skoplenii, s raspredeleniem veshestva v nih i tp.

Sama vspyshka byla otkryta 7 yanvarya 2006 goda. Za dva mesyaca tranzient izluchil okolo 1047 erg (t.e. okolo 1040 dzhoulei), v maksimume svetimost' pochti v 10 millionov raz prevoshodila solnechnuyu. Na meste vspyshki na arhivnyh snimkah net nikakoi yarkoi zvezdy, t.e. vspyshku nel'zya otnesti k aktivnosti LBV zvezd (yarkih golubyh peremennyh) tipa Eta Kilya. S drugoi storony, opticheskii tranzient sushestvenno slabee samyh slabyh sverhnovyh, no sushestvenno yarche izvestnyh novyh. Avtory polagayut, chto prichinoi vspyshki moglo stat' sliyanie dvuh obychnyh zvezd. V proshlom dvazhdy fiksirovalis' pohozhie vspyshki (v tumannosti Andromedy i v nashei galaktike), no izuchit' ih podrobno ne udavalos'.

Delo v tom, chto izmerit' pole napryamuyu ochen' neprosto. Poka eto bylo sdelano lish' dlya odnogo MPG vo vremya vspyshki, da i to nekotorye skeptiki podvergayut interpretaciyu etih nablyudenii somneniyu. S pomosh'yu dostatochno pryamyh nablyudenii avtory etoi stat'i podtverzhdayut magnitarnuyu prirodu odnogo iz ARP (hotya, opredelennye model'nye predpolozheniya avtoram vse-taki prishlos' sdelat').

Kneiske, Karl Mannheim Comments: 8 pages, 7 figures, accepted by A&A Fonovoe izluchenie est' vo vseh diapazonah. Gamma - ne isklyuchenie. Dannye so sputnika EGRET dotyanuli spektr fona do 30 GeV. Daleko ne vsegda izvestny vse sostavlyayushie fona, t.e. kakie istochniki vnosyat v nego vklad. Eto mogut byt' prosto slabye, kak govoryat "nerazreshennye", istochniki. Mozhet byt' diffuznyi fon, svyazannyi s mezhzvezdnoi ili mezhgalakticheskoi sredoi. Mozhet byt' chto-to eshe. V dannoi stat'e avtory rasmatrivayut vozmozhnost' togo, chto chast' gamma-fona na energiyah poryadka GeV i desyatkov GeV mozhet byt' svyazana s konversiei ochen' energichnyh gamma-fotonov ot dalekih blazarov. Neobhodimost' etogo svyazana s tem, chto ob'yasnit' ves' fon prosto izlucheniem blazarov udaetsya lish' pri ves'ma ekstremal'nyh predpolozheniyah. T.o., bylo neploho pridumat' dopolnitel'nyi istochnik GeVnyh fotonov, naprimer poluchit' ih iz bolee energichnyh, putem svoeobraznoi "peregonki". Konversiya svyazana so vzaimodeistviem gamma-fotonov s fotonami nizkih energii (poslednih v prostrastve predostatochno). Vyvod sostoit v tom, chto do 30 procentov fona mozhno svyazat' s etim processom. arxiv:0705.3889 Desyat' let raboty teleskopa Hobbi-Eberli (Ten Year Review of Queue Scheduling of the Hobby-Eberly Telescope) Authors: Matthew Shetrone et al.
