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: Multiple populations chemistry in NGC 2808
M. Latour, T. -O. Husser, B. Giesers +8
Galactic globular clusters (GCs) are now known to host multiple populations displaying particular abundance variations. The different populations within a GC can be well distinguis…
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…
Heavy-metal enrichment in the intermediate He-sdOB pulsator Feige 46
Marilyn Latour, Matti Dorsch, Ulrich Heber
The intermediate He-enriched hot subdwarf star Feige 46 was recently reported as the second member of the V366 Aqr (or He-sdOBV) pulsating class. Feige 46 is very similar to the pr…
Heavy metals in intermediate He-rich hot subdwarfs: The chemical composition of HZ44 and HD127493
Matti Dorsch, Marilyn Latour, Ulrich Heber
Hot subluminous stars can be spectroscopically classified as subdwarf B (sdB) and O (sdO) stars. While the latter are predominantly hydrogen deficient, the former are mostly helium…
PB 8783: the first sdO star suitable for asteroseismic modeling?
Valerie Van Grootel, Suzanna K. Randall, Marilyn Latour +5
Pulsating hot B subdwarf (sdB) stars, which are core-He burning objects, are one of the showcases of asteroseismology. Thanks to the combination of rich pulsation spectra and state…
Discovery of a second pulsating intermediate helium-enriched sdOB star
M. Latour, E. M. Green, G. Fontaine
We present the discovery of long-period, low-amplitude, g-mode pulsations in the intermediate He-rich hot subdwarf (sdOB) star Feige 46. Up until now only one other He-enriched sdO…
