Luminosity-colour relations for red clump stars
- 1. Istanbul Univ, Dept Astron & Space Sci, Fac Sci, TR-34119 Istanbul, Turkey
Description
We calibrated the absolute magnitudes M (V) , M (J) , and M (g) of red clump stars in terms of colours. M (V) and M (g) are strongly dependent on colour, while the dependence of M (J) and on colour is rather weak. The calibration of the absolute magnitudes M (V) and is tested on 101 RC stars in the field SA 141. The Galactic model parameters estimated with this sample are in good agreement with earlier studies.
