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 Šubr +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…
Understanding globular cluster abundances through nuclear reactions
P Adsley, M Williams, D S Harrouz +24
Globular clusters contain multiple stellar populations, with some previous generation of stars polluting the current stars with heavier elements. Understanding the history of globu…
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…
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…
Formation of massive black holes in ultra-compact dwarf galaxies: migration of primordial intermediate-mass black holes in N-body simulation
Henriette Wirth, Kenji Bekki
Recent observational studies of ultra-compact dwarf galaxies (UCDs) have discovered massive black holes (MBHs) with masses of more than , in their central regio…
Formation of massive globular clusters with dark matter and its implication on dark matter annihilation
Henriette Wirth, Kenji Bekki, Kohei Hayashi
Recent observational studies of -ray emission from massive globular clusters (GCs) have revealed possible evidence of dark matter (DM) annihilation within GCs. It is, however, s…
