Critical Rates of Stellar Mass Loss [PDF]
Symposium - International Astronomical Union, 1979 Many of the effects of mass loss on OB stars have now been explored. Mass loss will cause a star to be overluminous for its mass (though less luminous than a star of its original mass) and, for moderate mass-loss rates, the luminosity decreases at the same rate as the mass contained in the convective core decreases causing the main sequence lifetime to

Experimental study on high temperature combustion characteristic parameters of low rank coal
Meikuang Anquan, 2022 In order to study the combustion characteristics of low-order coal in high temperature oxidation process, the cone calorimeter was used to test the ignition time, heat release rate, total heat release, mass loss rate, total mass loss, CO release and ...

The evolution of red supergiant mass-loss rates [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 The fate of massive stars with initial masses >8M$_\odot$ depends largely on the mass-loss rate (\mdot ) in the end stages of their lives. Red supergiants (RSGs) are the direct progenitors to Type II-P core collapse supernovae (SN), but there is uncertainty regarding the scale and impact of any mass-loss during this phase.

The mass loss rate of γ Velorum [PDF]
Symposium - International Astronomical Union, 1979 The CIII λ 1909 absorption feature (deepest at V=−1600 Km s−1) in this star, observed by Burton et al (1975) and Johnson (1978), was predicted by Castor and Nussbaumer (1972). It implies a copious flow of CIII ions, because the oscillator strength is only fik = 1.6× 10−7.
