Stellar mass is a phrase that is used by astronomers to describe the mass of a star. It is usually enumerated in terms of the Sun's mass as a proportion of a solar mass (M☉). Hence, the bright star Sirius has around 2.02 M☉.[1] A star's mass will vary over its lifetime as...
Among the numerous applications are 1) measurement of the mass functions (MFs) of the bulge and disk 2) measurement of the relative normalizations of the bulge and disk MFs (and so their relative contribution to the Galactic potential), 3) measurement of the number of bulge white dwarfs and...
The newly discovered object, called HLX-1, is the first to show an intermediate weight between stellar-mass and supermassive black holes. 这个新发现的天体叫做HLX-1,是首个显示为中等质量的黑洞,介于恒星质量的黑洞和超大质量的黑洞之间。 huzhangao.blog.163.com 8. Containing several times the mass ...

Black holes should be quite common in the universe. There is indirect evidence thatstellar massblack holes (M∼10M⊙) are in X-ray binary systems and many galaxies host massive or supermassive (fromM∼106M⊙toM∼1010M⊙) black holes at their centers. Despite the great variety of phenome...

Most structural and evolutionary properties of galaxies strongly rely on the stellar initial mass function (IMF), namely the distribution of the stellar mass formed in each episode of star formation1,2,3,4. The IMF shapes the stellar population in all stellar systems, and so has become one of...
Aims. We use Hubble Space Telescope photometry for six rich,compact star clusters in the Large Magellanic Cloud (LMC), with agesranging from 0.01 to 1.0 Gyr, to derive the clusters' stellar massfunctions (MFs) at their half-mass radii. Methods. We derived the clusters' present-day MFs belo...
Significant core evolution is also observed in Magellanic Cloud clusters at early times. We find that this does not result from the action of black holes, but can be reproduced by the effects of mass-loss due to rapid stellar evolution in a primo 展开 ...
