Galaktikas sarkanā pudura zvaigžņu augstas izšķirtspējas spektrālie pētījumi

subject

description

Šajā darbā ir iepazītas zvaigžņu spektroskopijas metodes un darbs ar tam paredzētajām datorprogrammām. Ir veikta sarkanā pudura zvaigznes Omega Serpentis (HD 141680) augstas izšķirtspējas spektroskopija izmantojot spektru uzņēmumus, kas iegūti ar augstas izšķirtspējas spektrogrāfu SOFIN, kas uzmontēts Ziemeļvalstu Optiskajam Teleskopam (Nordic Optical Telescope), un noteikti zvaigznes galvenie fizikālie raksturlielumi, kā arī ķīmiskais sastāvs. Iegūtie rezultāti apstiprina, ka Omega Serpentis ir metāliem bagāta sarkanā pudura zvaigzne ar Saulei līdzīgu ķīmisko sastāvu. Veiktie pētījumi ļauj uzdot arī aptuvenas iespējamās HD 141680 masas vērtības robežas, kuras labi saskan ar teorētiski paredzēto sarkanā pudura zvaigžņu masu intervālu. Iegūtie rezultāti labi saskan ar Takeda et al. (2005) nesen iegūtajiem rezultātiem.
