Doppler HÜzmelenmesi Gösteren Çift Sistemlerde Fotometriden Dikine Hız Eldesi

Year 2020, Volume: 1 Issue: 2, 521 - 524, 11.12.2020

Abstract

Birbiri etrafında dolanan çift sistemler, yörünge eğiminin uygun olması durumunda, Doppler hüzmelenmesi(beaming) nedeniyle, çok düşük genlikte ışık değişimi gösterebilir. Bu küçük genlikler (ppm) ancak uzaytabanlı CoRoT ve Kepler gibi uyduların duyarlı fotometrik gözlemlerinden elde edilebilir. Bu değişim uygunşekilde modellendiğinde baş bileşenin dikine hız genliği fotometriden belirlenebilmektedir \citep[örneğin][]{2010ApJ...715...51V}.Bu türden hüzmelenme gösteren bir örten çift sistem olan HV Cnc’ninKepler ışık eğrisi bu etki dikkate alınarak modellenmiş ve baş bileşenin “fotometrik dikine hız” genliği(38.7+/-0.7 km/s) belirlenmiştir. Bu sonucun tayfsal dikine hız genliği (33.8+/-0.2 km/s) ile \citep{2003AJ....126.2954S}uyumlu çıkması, yöntemin başarısını göstermektedir.\\Ayrıca çift yıldızların verecekleri hüzmelenmenin, bileşen sıcaklıkları ve yörünge periyoduna göre değişimi de incelenmiştir.
