On the dynamical evolution of Cepheid multiplicity in star clusters and its implications for B-star multiplicity at birth
František Dinnbier, Richard I. Anderson, Pavel Kroupa
Classical Cepheid variable stars provide a unique probe to binary evolution in intermediate-mass stars over the course of several tens to hundreds of Myr. We studied the binary and…
The impact of a top-heavy IMF on the formation and evolution of dark star clusters
Ali Rostami Shirazi, Hosein Haghi, Akram Hasani Zonoozi +2
The Spitzer instability leads to the formation of a black hole sub-system (BHSub) at the center of a star cluster providing energy to luminous stars (LSs) and increasing their rate…
Effects of physical conditions on the stellar initial mass function: The low-metallicity star-forming region Sh 2-209
Marie Zinnkann, Henriette Wirth, Pavel Kroupa
Recent work suggested that the variation of the initial mass function (IMF) of stars depends on the physical conditions, notably, the metallicity and gas density. We investigated t…
