D What causes massive stars to lose mass at a high rate through stellar winds? a. radiation pressure b. high magnetic fields WebCharacteristics of Main Sequence Stars Main-sequence stars obey several relations (which are mostly pre-dictable from homology). • Main sequence stars obey a mass-luminosity relation, with L ∝ Mη. The slope η changes slightly over the range of masses; be-tween 1 and 10M¯, η ≈ 3.88. The relation flattens out at higher
WebListed following are characteristics that describe either high-mass or low-mass stars. Match these characteristics to the appropriate category.

WebThe Hertzsprung–Russell diagram, or H–R diagram, is a plot of stellar luminosity against surface temperature. Most stars lie on the main sequence, which extends diagonally across the H–R diagram from high temperature and high luminosity to low temperature and low luminosity. The position of a star along the main sequence is determined by ...
In astronomy, the main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness. These color-magnitude plots are known as Hertzsprung–Russell diagrams after their co-developers, Ejnar Hertzsprung and Henry Norris Russell.
