Discovery of a double white dwarf in the Galactic globular cluster NGC 6397
Fabian Göttgens, Marilyn Latour, Ulrich Heber +4
Binaries in the cores of globular clusters are known to prevent the gravitational collapse of the cluster, and simulations predict that the core of NGC 6397 contains a large number…
Tracing stellar rotation in young massive LMC clusters
Sebastian Kamann, Nate Bastian, Florian Niederhofer +8
We present a detailed analysis of stellar rotation along the main sequences of NGC 1866 and NGC 1856, two young (~200-300 Myr) massive clusters in the Large Magellanic Cloud, using…
Binary properties of the globular cluster 47 Tuc (NGC 104). A dearth of short-period binaries
Johanna Müller-Horn, Fabian Göttgens, Stefan Dreizler +4
Spectroscopic observations of binary stars in globular clusters are essential to shed light on the poorly constrained period, eccentricity, and mass ratio distributions and to deve…
Studying Binary Systems in Omega Centauri with MUSE. I. Detection of Spectroscopic Binaries
F. Wragg, S. Kamann, S. Saracino +6
NGC 5139 ( Cen), is the closest candidate of a Nuclear Star Cluster that has been stripped of its host galaxy in the Milky Way. Despite extensive studies through the last decad…
