Evidence for top-heavy stellar initial mass functions with increasing density and decreasing metallicity
formation mass-functionlatetype globular clusters general top-heavy stellar metallicity
2012/2/23
Residual-gas expulsion after cluster formation has recently been shown to leave an imprint in the low-mass present-day stellar mass function (PDMF) which allowed the estimation of birth conditions of ...

GENERALISED SCHUSTER DENSITY LAW spherical symmetry stellar
2009/3/26
A special case of the generalised Schuster density law for stellar
systems with spherical symmetry is discussed; here the exponent in the denominator
is equal to i/2 where i is a positive integer. ...
Assuming that the disc of our Galaxy, the Milky Way, obeys the
classical exponential law, that it is maximal and the Sun is rather far from the
maximum of its circular velocity, one ¯nds that, ...
