The distance to the Galactic center determined by G, K, and M stars

Branham, Richard L.

The distance from the Sun to the center of the Galaxy R0 remains a fundamental parameter for Galactic structure. This study uses 105,275 G, K, and M stars of all luminosity classes with position, parallax, and proper motion taken …

Bilir, S.; Ak, T.; Karaali, S. +4 more

We used the updated [Fe/H] abundances of 168 F-G type dwarfs and calibrated them to a third order polynomial in terms of reduced ultraviolet excess, δ0.41 defined with
