Tidal tails in open clusters: Morphology, binary fraction, dynamics, and rotation
Ira Sharma, Vikrant V. Jadhav, Annapurni Subramaniam +1
Context: This research presents unsupervised machine learning and statistical methods to identify and analyze tidal tails in open star clusters using data from the Gaia DR3 catalog…
Failed supernova explosions increase the duration of star formation in globular clusters
Henriette Wirth, Jaroslav Haas, Ladislav Å ubr +3
Context. The duration of star formation (SF) in globular clusters (GCs) is an essential aspect for understanding their formation. Contrary to previous presumptions that all stars a…
The masses of open star clusters and their tidal tails and the stellar initial mass function
Henriette Wirth, František Dinnbier, Pavel Kroupa +1
Unresolved binaries have a strong influence on the observed parameters of stellar clusters (SCs). We quantify this influence and compute the resulting mass underestimates and stell…
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…
