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…
Kinematic differences between multiple populations in Galactic globular clusters
Sven Martens, Sebastian Kamann, Stefan Dreizler +7
The formation process of multiple populations in globular clusters is still up for debate. Kinematic differences between the populations are particularly interesting in this respec…
The MAVERIC Survey: The first radio and X-ray limits on the detached black holes in NGC 3201
Alessandro Paduano, Arash Bahramian, James C. A. Miller-Jones +11
The Galactic globular cluster NGC 3201 is the first Galactic globular cluster observed to host dynamically-confirmed stellar-mass black holes, containing two confirmed and one cand…
Central kinematics of the Galactic globular cluster M80
Fabian Göttgens, Sebastian Kamann, Holger Baumgardt +7
We use spectra observed with the integral-field spectrograph MUSE to reveal the central kinematics of the Galactic globular cluster Messier 80 (M80, NGC 6093). Using observations o…
How stellar rotation shapes the colour magnitude diagram of the massive intermediate-age star cluster NGC 1846
Sebastian Kamann, Nate Bastian, Seth Gossage +19
We present a detailed study of stellar rotation in the massive 1.5 Gyr old cluster NGC 1846 in the Large Magellanic Cloud. Similar to other clusters at this age, NGC 1846 shows an…
The peculiar kinematics of the multiple populations in the globular cluster Messier 80 (NGC 6093)
Sebastian Kamann, Emanuele Dalessandro, Nate Bastian +10
We combine MUSE spectroscopy and Hubble Space Telescope ultraviolet (UV) photometry to perform a study of the chemistry and dynamics of the Galactic globular cluster Messier 80 (M8…
The binary content of multiple populations in NGC 3201
Sebastian Kamann, Benjamin Giesers, Nate Bastian +7
We investigate the binary content of the two stellar populations that coexist in the globular cluster NGC 3201. Previous studies of binary stars in globular clusters have reported…
A stellar census in globular clusters with MUSE: A spectral catalogue of emission-line sources
Fabian Göttgens, Tim-Oliver Husser, Sebastian Kamann +6
Globular clusters produce many exotic stars due to a much higher frequency of dynamical interactions in their dense stellar environments. Some of these objects were observed togeth…
A stellar census in globular clusters with MUSE: Binaries in NGC 3201
Benjamin Giesers, Sebastian Kamann, Stefan Dreizler +8
We utilize multi-epoch MUSE spectroscopy to study binaries in the core of NGC 3201. Our sample consists of 3553 stars with 54883 spectra in total comprising 3200 main-sequence star…
Discovery of an old nova remnant in the Galactic globular cluster M 22
Fabian Göttgens, Peter M. Weilbacher, Martin M. Roth +11
A nova is a cataclysmic event on the surface of a white dwarf in a binary system that increases the overall brightness by several orders of magnitude. Although binary systems with…
