An Outer Giant Planet or Brown Dwarf in the 51 Pegasi System?
Marvin Morgan, Brendan P. Bowler, Kyle Franson +15
51 Pegasi harbors the first confirmed extrasolar planet orbiting a Sun-like star. Decades of continued radial velocity (RV) observations have since uncovered signatures of an addit…
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…
Searching for exotic object companions in the dense core of NGC 362: a multi-wavelength and multi-epoch photometric analysis
Greta Ettorre, Emanuele Dalessandro, Cristina Pallanca +8
The dense cores of globular clusters (GCs) are efficient environments for the production of exotic stellar populations, including millisecond pulsars (MSPs), low-mass X-ray binarie…
Studying Binary Systems in Omega Centauri with MUSE: II. Observational constraints on the orbital period distribution
S. Saracino, S. Kamann, F. Wragg +8
Omega Centauri ( Cen) is one of the most complex star clusters in the Milky Way, and likely the stripped nucleus of an accreted dwarf galaxy. Being the subject of debate betwee…
A stellar census in globular clusters with MUSE. Metallicity spread and dispersion among first-population stars
M. Latour, S. Kamann, S. Martocchia +3
Multiple populations are ubiquitous in the old massive globular clusters (GCs) of the Milky Way. It is still unclear how they arose during the formation of a GC. The topic of iron…
