The initial mass function of stars and the star-formation rates of galaxies
Pavel Kroupa, Tereza Jerabkova
The measured star-formation rates (SFRs) of galaxies comprise an important constraint on galaxy evolution and also on their cosmological boundary conditions. Any available tracer o…
On the dynamical evolution of Cepheids in star clusters
František Dinnbier, Richard I. Anderson, Pavel Kroupa
We investigate the occurrence of classical (type-I) Cepheid variable stars (henceforth: Cepheids) in dynamically evolving star clusters from birth to an age of approximately 300 My…
Estimating the ages of open star clusters from properties of their extended tidal tails
František Dinnbier, Pavel Kroupa, Ladislav Šubr +1
The most accurate current methods for determining the ages of open star clusters, stellar associations and stellar streams are based on isochrone fitting or the lithium depletion b…
A possible solution to the Milky Way's binary-deficient retrograde stellar population. Evidence that Centauri has formed in an extreme starburst
M. Marks, P. Kroupa, J. Dabringhausen
Context. The fraction of field binaries on retrograde orbits about the Milky Way is significantly lower compared to its prograde counterpart. Chemical and dynamical evidence sugges…
BiPoS1 -- a computer programme for the dynamical processing of the initial binary star population
J. Dabringhausen, M. Marks, P. Kroupa
The first version of the Binary Population Synthesizer (BiPoS1) is made publicly available. It allows to efficiently calculate binary distribution functions after the dynamical pro…
Are disks of satellites comprised of tidal dwarf galaxies?
Michal Bílek, Ingo Thies, Pavel Kroupa +1
It was found that satellites of nearby galaxies can form flattened co-rotating structures called disks of satellites or planes of satellites. Their existence is not expected by the…
