| Abstract: |
The recent works devoted to improving empirical Mass-Luminosity
Relation (MLR) for main sequence stars are reviewed in this paper.
In the mass-luminosity plane, the observational data are subjected
to non-negligible errors in both coordinates with different
dimensions. In order to obtain more reliable results, a more
reasonable weight-assigning scheme is needed. Such a scheme is
developed, with which each data point can have its own due
contribution. For low mass stars (smaller than ∼1M⊙),
three-piecewise continuous improved MLRs in K, J and H bands are
obtained respectively. For visual band, improved MLR for stars with
mass spanning from 0.12M⊙ to 22.89 M⊙, and improved
MMLR (mass-metallicity-luminosity relation) for low mass stars which
is based on our K band MLR and available observational metallicity
data are provided. Further improvements of MLR would have to come
from future observations. |
