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…
No evidence for intermediate-mass black holes in the globular clusters Cen and NGC 6624
Holger Baumgardt, Chenyu He, Sarah M. Sweet +8
We compare the results of a large grid of N-body simulations with the surface brightness and velocity dispersion profiles of the globular clusters Cen and NGC 6624. Our models…
The CARMENES search for exoplanets around M dwarfs Detection of a mini-Neptune around LSPM J2116+0234 and refinement of orbital parameters of a super-Earth around GJ 686 (BD+18 3421)
S. Lalitha, D. Baroch, J. C. Morales +34
Although M dwarfs are known for high levels of stellar activity, they are ideal targets for the search of low-mass exoplanets with the radial velocity (RV) method. We report the di…
