I v astrofizike pri primenenii taih raschetov est' nekotoryi raznoboi: raznye gruppy ispol'zuyut raznye modeli i raschety.

V kakih-to aspektah, po vsei vidimosti, avtory idut na povodu lichnyh pristrastii (poskol'ku istochnikov velikoe mnozhestvo), gde-to mozhno bylo vklyuchit' bolee svezhie ssylki, tem ne menee ochen' poleznaya shtuka.

Razumeetsya, kakoe-to kolichestvo chastic temnogo veshestva okazyvaetsya vnutri zvezd. Eti chasticy mogut annigilirovat' drug s drugom, i lyudi davno zadumalis' nad vozmozhnymi posledstviyami. Na pal'cah posledstviya ochen' prosty. Vydelyaetsya dopolnitel'naya energiya, povyshaetsya temperatura. Zvezda (ili protozvezda) slegka rasshiryaetsya, chto ponizhaet temp yadernyh reakcii v zvezde, t.e. formirovanie zvezdy otkladyvaetsya ili zhe zvezda budet zhit' dol'she, poskol'ku medlennee rashoduet "goryuchee". Kachestvenno vse yasno, vopros s kolichestvennymi harakteristikami. Avtory ispol'zuyut odin iz luchshih v mire kodov po raschetu zvezdnoi evolyucii, chtoby posmotret' naskol'ko mozhno uvelichit' zhizn' zvezdy pri raznoi plotnosti temnogo veshestva. Imenno plotnost' chastic temnoi materii okazyvaetsya klyuchevym parametrom. Esli etih chastic nabrat' dostatochno mnogo, to - o chudo! - massivnaya pervozvezda mozhet voobshe dozhit' do nashih dnei. Odnako avtory ne issleduyut naskol'ko chasto takaya plotnost' budet nabirat'sya. Skoree vsego eto dostatochno redkaya situaciya.
