A Long Period Stellar-Mass Black Hole Binary in Centauri
Matthew Whitaker, Evan Kerr, Anil Seth +16
Modern simulations of stellar dynamics in globular clusters peg a dominant role for stellar-mass black holes, but direct evidence for black holes in clusters remains limited. We pr…
Stellar rotation and binaries in open clusters with Gaia DR3
Elena Pancino, Elisabetta Reggiani, Silvia Marinoni +14
Stellar rotation is a fundamental ingredient in shaping the evolution of stars and it can also be used to trace past stellar interactions. Yet, systematic studies of stellar rotati…
The MUSE-Faint survey V. The binary fraction of Leo T
Daniel Vaz, Jarle Brinchmann, Sebastian Kamann +3
The Leo T dwarf galaxy, the faintest and least massive galaxy known to have recent star formation (), exhibits a high dynamical mass-to-light ratio based on its stellar…
oMEGACat. IX. Chemical Tagging of Omega Centauri Populations with Machine-Learning-Inferred Abundances from the MUSE Spectrograph
Z. Wang, A. C. Seth, C. Clontz +14
We present chemical abundance measurements for 7,302 red giant branch stars within the half-light radius (~5') of Centauri ( Cen), derived from MUSE spectra using the neur…
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…
The SPace-based InterFerometer Feasibility (SPIFF) Project: Enabling Future High-Resolution Astronomy Across the EM Spectrum
Berke Vow Ricketti, Victoria Yankelevich, Chris Benson +19
A plethora of astronomical science cases can only be achieved with high angular resolution observations, and we can expect the number of these to grow as astronomers are constraine…
