Asymmetrical tidal tails of open star clusters: stars crossing their cluster's prah challenge Newtonian gravitation

Pavel Kroupa, Tereza Jerabkova, Ingo Thies +14

After their birth a significant fraction of all stars pass through the tidal threshold (prah) of their cluster of origin into the classical tidal tails. The asymmetry between the n…

The giants that were born swiftly -- Implications of the top-heavy stellar initial mass function on the birth conditions of globular clusters

Henriette Wirth, Pavel Kroupa, Jaroslav Haas +3

Recent results suggest that the initial mass function (IMF) of globular clusters (GCs) is metallicity and density dependent. Here it is studied how this variation affects the initi…

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…

How many explosions does one need? -- Quantifying supernovae in globular clusters from iron abundance spreads

Henriette Wirth, Tereza Jerabkova, Zhiqiang Yan +3

Many globular clusters (GCs) are known to host multiple populations distinguishable by their light-element content. Less common are GCs displaying iron abundance spreads which are…

Very high redshift quasars and the rapid emergence of super-massive black holes

Pavel Kroupa, Ladislav Subr, Tereza Jerabkova +1

The observation of quasars at very high redshift such as Poniuaena is a challenge for models of super-massive black hole (SMBH) formation. This work presents a study of SMBH format…

Do star clusters form in a completely mass-segregated way?

Václav Pavlík, Pavel Kroupa, Ladislav Šubr

ALMA observations of the Serpens South star-forming region suggest that stellar protoclusters may be completely mass segregated at birth. Independent observations also suggest that…
