You Shall Not Pass! The propagation of low/moderate powered jets through a turbulent interstellar medium
Olga Borodina, Yueying Ni, Jake S. Bennett +6
Feedback from black hole-powered jets has been invoked in many cosmological simulations to regulate star formation and quench galaxies. Despite this, observational evidence of how…
Star-by-star dynamical evolution of the physical pair of the Collinder 135 and UBC 7 open clusters
Maryna Ishchenko, Dana A. Kovaleva, Peter Berczik +8
In a previous paper using Gaia DR2 data, we demonstrated that the two closely situated open clusters Collinder 135 and UBC 7 might have formed together about 50 Myr ago. In this wo…
On the Tremaine-Weinberg method: how much can we trust gas tracers to measure pattern speeds?
Olga Borodina, Thomas G. Williams, Mattia C. Sormani +2
Pattern speeds are a fundamental parameter of the dynamical features (e.g. bars, spiral arms) of a galaxy, setting resonance locations. Pattern speeds are not directly observable,…
The bound mass of Dehnen models with centrally peaked star formation efficiency
B. Shukirgaliyev, A. Otebay, M. Sobolenko +12
Understanding the formation of star clusters with low star-formation efficiency (SFE) is very important to know about the star-formation history. In N-body models of star cluster e…
Unresolved multiple stars and Galactic clusters' mass estimates
Olga I. Borodina, Giovanni Carraro, Anton F. Seleznev +1
If not properly accounted for, unresolved binary stars can induce a bias in the photometric determination of star cluster masses inferred from star counts and the luminosity functi…
Damped perturbations in stellar systems: Genuine modes and Landau-damped waves
Evgeny V. Polyachenko, Ilia G. Shukhman, Olga I. Borodina
This research was stimulated by the recent studies of damping solutions in dynamically stable spherical stellar systems. Using the simplest model of the homogeneous stellar medium,…
Unresolved binaries and Galactic clusters' mass estimates
Olga I. Borodina, Anton F. Seleznev, Giovanni Carraro +1
Binary stars are present in all stellar systems, yet their role is far from being fully understood. We investigate the effect of unresolved binaries in the derivation of open clust…
