Basic Parameters, Fundamental Relations and Bolometric Corrections of Solar Neighborhood Main-Sequence Stars

Zeki Eker, Faruk Soydugan, Selçuk Bilir, Volkan Bakış

The published masses, radii and effective temperatures of 509 main-sequence stars chosen from the catalogue of detached double-lined eclipsing binaries with metal abundances 0.008 ≤ Z ≤ 0.040 in the solar neighborhood within the disk were used to calibrate interrelated mass-luminosity (MLR), mass-radius (MRR) and mass-effective temperature (MTR) relations. 34 more stars (20 binaries) from the same catalog with unpublished effective temperatures added after computing their effective temperatures using newly defined fundamental relations (MLR, MRR, MTR). Binaries compiled were searched if they have light ratios (L2/L1) in the V band together with trigonometric parallaxes and visual apparent magnitudes. 225 systems (440 stars) were found eligible to calculate bolometric corrections (BC). NASA/IPAC Galactic dust maps were used to estimate extinctions. Systems with unreliable extinctions (dusty regions and/or b ≤ 5°) were replaced with private determinations. The computed BC values were reduced again by choosing the systems with most accurate parallaxes (σπ/π< 0.07) for a calibration sample (322 stars). Main-sequence BC – Teff relation valid from 3000 to 30000 K in the form a cubic function is determined using the basic stellar parameters in the calibration sample.
