Inverse Dynamical Population Synthesis and Star Formation
Pavel Kroupa
We investigate the hypothesis that stars form in aggregates of binary systems and that the dynamical evolution of these aggregates leads to the observed properties of binary stars…
The Dynamical Properties of Stellar Systems in the Galactic Disc
Pavel Kroupa
We postulate that most stars are born in aggregates of binary systems which are dynamically equivalent to the `dominant mode cluster'. The initial binary orbits are consitent with…
Star Cluster Evolution, Dynamical Age Estimation and the Kinematical Signature of Star Formation
Pavel Kroupa
We use N-body integration to follow the evolution of clusters of 200 binary systems with different initial half mass radii . We also simulate single-star clusters. All clu…
UNIFICATION OF THE NEARBY AND PHOTOMETRIC STELLAR LUMINOSITY FUNCTIONS
Pavel Kroupa
We introduce a model Galactic field low-mass stellar population that has a proportion of binary systems as observed, with a mass ratio distribution consistent with observational co…
ARE THE NEARBY AND PHOTOMETRIC STELLAR LUMINOSITY FUNCTIONS DIFFERENT?
Pavel Kroupa
The stellar luminosity function derived from the sample of stars within 5.2--20~pc is the nearby luminosity function. The luminosity function obtained from deep low spatial resolut…
