WebIn other words, stars form from the collapsing cores of molecular clouds, and the distribution of cores is already biased towards there being more low-mass cores than high-mass cores (this is in fact observed in molecular clouds). So you naturally end up with more low-mass stars than high-mass stars. WebThe Pleiades has a few very bright stars and lots of less luminous (lower-mass) stars. The M3 cluster has only fainter stars on the main sequence. It also has lots of Red Giants, but that is another story.

WebThe cloud is initially 1.2 light-years (9.5 million million kilometres) in diameter, with a temperature of 10 Kelvin (-263 degrees Celsius). In a newly formed star cluster, there are many more stars with low masses than stars with high masses. WebIn astronomy, surface brightness (SB) quantifies the apparent brightness or flux density per unit angular area of a spatially extended object such as a galaxy or nebula, or of the night sky background. An object's surface brightness depends on its surface luminosity density, i.e., its luminosity emitted per unit surface area. derisio construction bathroomWebof SN 2005cg is likely to have many similarities to high-z SN hosts: low mass, high gas content, strong star formation, low metallicity, and perhaps environmental perturbations.
