The big problems in star formation: the star formation rate, stellar clustering, and the initial mass function
MR Krumholz - Physics Reports, 2014 - Elsevier
Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

The role of magnetic fields in setting the star formation rate and the initial mass function
Star-forming gas clouds are strongly magnetized, and their ionization fractions are high
enough to place them close to the regime of ideal magnetohydrodyamics on all but the …

When did the initial mass function become bottom-heavy?
The characteristic mass that sets the peak of the stellar initial mass function (IMF) is closely
linked to the thermodynamic behaviour of interstellar gas, which controls how gas fragments …

Galaxies as simple dynamical systems: observational data disfavor dark matter and stochastic star formation
P Kroupa - Canadian Journal of Physics, 2015 - cdnsciencepub.com
According to modern theory, galactic evolution is driven by the dynamics of dark matter and
stochastic star formation, but galaxies are observed to be simple systems. The existence of …

3D morphology of open clusters in the solar neighborhood with Gaia EDR 3: its relation to cluster dynamics
We analyze the 3D morphology and kinematics of 13 open clusters (OCs) located within 500
pc of the Sun, using Gaia EDR 3 and kinematic data from the literature. Members of OCs are …
