Oort Sabitlerinin Yıldız Rengine Göre Değişimi

Year 2020, Volume: 1 Issue: 1, 255 - 256, 11.12.2020

Abstract

Oort sabitleri, Samanyolu Galaksimizin yerel dönme özelliğini karakterize eden sabitlerdir. Bu sabitler, yıldızların galaktik konumları ($l$) ve hareketlerine ($\mu_l$) doğrudan bağlıdır. Bu çalışmanın amacı, Hipparcos Kataloğunda yer alan yıldızları kullanarak, farklı $B-V$ renk aralığındaki yıldızlar için Oort sabitlerini belirlemektir. Oort sabitlerinin duyarlı değerleri \cite{feast:whitelock1} tarafından $A=14.82$ km/s/kpc ve $B=-12.37$ km/s/kpc olarak verilmektedir. Hipparcos kataloğundaki farklı $B-V$ renk aralığındaki yıldız gruplarına bakıldığında, renkleri $0.0
