Naberite v guglyah - fizicheskie dvoinye zvezdy foto,
i mnogo Vy fotografii naidete?
Sploshnye risunki v astronomii, risuyut azh gai shumit.
Pochitaite sami pro dvoinye, tam nikakoi konkretiki,
i ne ponyatno to-li eto deistvuyushii vulkan na zvezde,
to-li eto otdel'no letyashaya zvezda.
I zamet'te prakticheski polnoe otsutstvie fotografii fizicheskih dvoinyh.

\\\Poyasnenie: Vy vidite, kakaya zvezda ból'shaya v dvoinoi sisteme, izobrazhennoi na kartinke?\\\

\\\Inogda na nochnom nebe mozhno zametit' dve ili neskol'ko blizko raspolozhennyh zvezdy. Te iz nih, kotorye na samom dele daleki drug ot druga i ne imeyut kakoi-libo fizicheskoi svyazi mezhdu soboi, nazyvayutsya opticheskimi dvoinymi zvezdami. Vizual'no oni kazhutsya blizkimi, t.k. proektiruyutsya v ochen' blizkie tochki na nebesnoi sfere. V otlichie ot nih, fizicheskimi dvoinymi nazyvayut zvezdy, kotorye obrazuyut edinuyu dinamicheskuyu sistemu i obrashayutsya vokrug obshego centra mass pod deistviem sil vzaimnogo prityazheniya. Inogda mozhno nablyudat' ob'edineniya treh i dazhe bolee zvezd (tak nazyvaemye troinye i kratnye sistemy). Esli oba komponenta dvoinoi zvezdy dostatochno udaleny drug ot druga, tak chto vidny razdel'no, to takie dvoinye nazyvayut vizual'no dvoinymi. Dvoistvennost' par, komponenty kotoryh ne vidny v otdel'nosti, mozhet byt' obnaruzhena libo fotometricheski (naprimer, zatmennye peremennye zvezdy), libo spektroskopicheski (naprimer, spektral'no-dvoinye).\\\

\\\Sredi dvoinyh zvezd razlichayut fizicheskie i opticheskie pary. Fizicheskie pary predstavlyayut soboi sistemy blizko raspolozhennyh v prostranstve zvezd, svyazannyh silami tyagoteniya i obrashayushihsya okolo obshego centra tyazhesti po zakonam Keplera. Opticheskie pary, naoborot, sostoyat iz ves'ma daleko raspolozhennyh drug ot druga v prostranstve zvezd, sluchainym obrazom proektiruyushihsya na nebesnuyu sferu vblizi odnogo napravleniya. Dlya astronomii takie pary ne predstavlyayut interesa.
Fizicheskie dvoinye zvezdy imeyut dlya astronomii kak nauki v celom fundamental'noe znachenie. Astronomy mnogih stran izuchayut eti zvezdy uzhe bolee dvuh vekov, i interes k nim ne oslabevaet\\\
----------------------------------------
Vot zdes' zamechu chto v stat'e
net ssylki na fizicheskie dvoinye zvezdy,
na vse ssylki est' a na eto net.
