In summary, the equation for calculating the lifetime of a star is k*m/l, where k is a constant, m is the mass of the star, and l is the star's luminosity. Using this equation, it can be determined that a star with 24 solar masses and 300,000 times the luminosity of the s...
We present an empirical determination of the mass-loss rate as a function of stellar luminosity and effective temperature, for oxygen-rich dust-enshrouded Asymptotic Giant Branch stars and red supergiants. To this aim we obtained optical spectra of a sample of dust-enshrouded red giants in the ...
Stellar Structure and the Origin of Stellar Energy The 'formula for the luminosity? of a star makes the luminosity very nearly proportional to its effective temperature, and so the so-called proof of the mass-luminosity law involves a semi-empirical element, namely, an appeal to the... EA ...
of energy, in joules (J) per second, emitted from one square meter of an object's surface, and by that definition, it's obviously related to the total amount of energy a star radiates in one second, known more formally as luminosity, as well as surface area.Read Wien's Law vs. ...
and we find an intrinsic luminosity ofLLyα= 1.9 × 1042erg s-1, extending to 33 kpc. We find that the LAB is associated with a group of galaxies, and possibly a protocluster, in agreement with previous studies that find LABs in overdensities. In addition to Lyman-α(Lyα) emission,...

The main influence on the mass loss rate is given by the stellar temperature, the stellar mass and luminosity. The influence of the carbon abundance, the pulsational period and the amplitude of the piston are almost negligible. As this mass loss equation is based on physical models it is ...
