Abstract

Conventional mass- luminosity (M- L) relations are defined using 509 nearby main- sequence (MS) stars within the Solar neighborhood. A smooth mass- radius (M- R) relation was fixed from radii of MS stars appeared in literature having masses within the limits 0.179- 1.5 M. Similarly, a smooth mass- effective temperature (M- Teff) relation was derived for the main- sequence stars having masses within the limits 1.5- 31 M using their effective temperatures available. The omitted parts of M- R and M- Teff relations in the range from 0.179 to 31 M were computed according to Stephan- Boltzmann law, so inter- related M- L, M- R and M- Teff were achieved.
