A possible solution to the Milky Way's binary-deficient retrograde stellar population. Evidence that Centauri has formed in an extreme starburst
M. Marks, P. Kroupa, J. Dabringhausen
Context. The fraction of field binaries on retrograde orbits about the Milky Way is significantly lower compared to its prograde counterpart. Chemical and dynamical evidence sugges…
How fast is mass-segregation happening in hierarchical formed embedded star clusters?
R. Dominguez, M. Fellhauer, M. Blana +2
We investigate the evolution of mass segregation in initially sub-structured young embedded star clusters with two different background potentials mimicking the gas. Our clusters a…
Understanding the internal dynamics of elliptical galaxies without non-baryonic dark matter
J. Dabringhausen, P. Kroupa, B. Famaey +1
Assuming virial equilibrium and Newtonian dynamics, low-mass early-type galaxies have larger velocity dispersions than expected from the amount of baryons they contain. The convent…
Could Segue 1 be a destroyed star cluster? - a dynamical perspective
Raul Dominguez, Michael Fellhauer, Matias Blaña +5
We attempt to find a progenitor for the ultra-faint object Segue 1 under the assumption that it formed as a dark matter free star cluster in the past. We look for orbits, using the…
Co-orbiting satellite galaxy structures are still in conflict with the distribution of primordial dwarf galaxies
Marcel S. Pawlowski, Benoit Famaey, Helmut Jerjen +11
Both major galaxies in the Local Group host planar distributions of co-orbiting satellite galaxies, the Vast Polar Structure (VPOS) of the Milky Way and the Great Plane of Andromed…
Dwarf elliptical galaxies as ancient tidal dwarf galaxies
Jörg Dabringhausen, Pavel Kroupa
The formation of tidal dwarf galaxies (TDGs) is triggered by the encounters of already existing galaxies. Their existence is predicted from numerical calculations of encountering g…
Top-heavy IMFs in ultra compact dwarf galaxies?
Jörg Dabringhausen, Pavel Kroupa
Ultra compact dwarf galaxies (UCDs) are dense stellar systems at the border between massive star-clusters and small galaxies. Their on average high optical mass-to-light (M/L) rati…
Local-Group tests of dark-matter Concordance Cosmology: Towards a new paradigm for structure formation
P. Kroupa, B. Famaey, K. S. de Boer +7
(abridged) Predictions of the Concordance Cosmological Model (CCM) of the structures in the environment of large spiral galaxies are compared with observed properties of Local Grou…
