Current data on the globular cluster Palomar 14 are not inconsistent with MOND
Gianfranco Gentile, Benoit Famaey, Garry W. Angus +1
Certain types of globular clusters have the very important property that the predictions for their kinematics in the Newtonian and modified Newtonian dynamics (MOND) contexts are d…
The origin of very wide binary systems
M. B. N. Kouwenhoven, S. P. Goodwin, Richard J. Parker +3
The majority of stars in the Galactic field and halo are part of binary or multiple systems. A significant fraction of these systems have orbital separations in excess of thousands…
Constraining the initial mass function of stars in the Galactic Centre
Ulf Loeckmann, Holger Baumgardt, Pavel Kroupa
(abridged) Here we discuss the question whether the extreme circumstances in the centre of the Milky Way may be the reason for a significant variation of the IMF. By means of stell…
Globular Clusters and Satellite Galaxies: Companions to the Milky Way
Duncan A. Forbes, Pavel Kroupa, Manuel Metz +1
Our Milky Way galaxy is host to a number of companions. These companions are gravitationally bound to the Milky Way and are stellar systems in their own right. They include a popul…
Influence of a stellar cusp on the dynamics of young stellar discs and the origin of the S-stars in the Galactic Centre
Ulf Löckmann, Holger Baumgardt, Pavel Kroupa
Observations of the Galactic Centre show evidence of one or two disc-like structures of very young stars orbiting the central super-massive black hole within a distance of a few 0.…
Do binaries in clusters form in the same way as in the field?
Richard J. Parker, Simon P. Goodwin, Pavel Kroupa +1
We examine the dynamical destruction of binary systems in star clusters of different densities. We find that at high densities (10^4 - 10^5 Msun pc^-3) almost all binaries with sep…
