Basık yörüngeli erken B tipi örten çift sistemlerin eksen dönmesi analizi: V466 Car, V529 Car ve MN Tra

Abstract

Bu çalışmada, basık yörüngeli örten çift sistemler içinden seçilen V466 Car, V529 Car ve MN Tra sistemlerinin eksen dönmesi analizleri (O-C) diyagramları kullanılarak yapılmış, eksen dönme parametreleri ilk kez hesaplanmıştır. Eksen dönmesi analizi için kullanılan minimum zamanları (O–C) Gateway veri tabanından alınmıştır.  Analizler sonucunda V466 Car, V529 Car ve MN Tra sistemlerinin yörünge dış merkezlikleri, sırasıyla, 0.205 ± 0.035, 0.497 ± 0.077, 0.282 ± 0.042, enberi noktasının boylamındaki ilerlemelerin hızı 0.0194 ± 0.0013, 0.0055 ± 0.0016, 0.0026 ± 0.0007 º/çevrim, bunlara karşılık gelen eksen dönme dönemleri ise 175 ± 12, 858 ± 203, 894 ± 204 yıl, olarak elde edilmiştir.

Apsidal motion analysis of early B-type eclipsing binary systems: V466 Car, V529 Car and MN Tra

Abstract

In the present study, the eclipsing binaries which displaying apsidal motion effect in their orbits, V466 Car, V529 Car and MN Tra were analyzed by using (O-C) diyagrams to obtain the parameters of apsidal motion.  The minima times taken from (O–C) Gateway database were used for the apsidal motion analysis.  We found the orbital eccentricities 0.205 ± 0.035, 0.497 ± 0.077 and 0.282 ± 0.042, the rates of change of the longitude of periastron 0.0194 ± 0.0013, 0.0055 ± 0.0016, 0.0026 ± 0.0007 º/cycle, corresponding to the apsidal motion periods of about 175 ± 12, 858 ± 203 and 894 ± 204 years, for V466 Car, V529 Car and MN Tra, respectively.
