Euclid: The convective-transition gap of 47 Tuc
M. Libralato, M. Griggio, R. Gerasimov +140
We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…
Revisiting the near infrared Calcium triplet as metallicity indicator
M. Navabi, R. Carrera, N. E. D. Noël +3
The near-infrared Calcium II Triplet (CaT), around 850nm, is a key metallicity indicator for red giant stars. We present a revised [Fe/H] calibration as a function of CaT line stre…
Using Binary Population Synthesis to Calculate the Yields of Low- and Intermediate-Mass Binary Populations at Low Metallicity
Zara Osborn, Amanda Karakas, Devika Kamath +3
Asymptotic giant branch (AGB) stars are important to chemical evolution at metallicity () as they contribute significantly to the produc…
A high fraction of close massive binary stars at low metallicity
H. Sana, T. Shenar, J. Bodensteiner +74
At high metallicity, a majority of massive stars have at least one close stellar companion. The evolution of such binaries is subject to strong interaction processes, heavily impac…
Observational mapping of the mass discrepancy in eclipsing binaries. A new self-contained framework for concurrent analysis of photometric and spectroscopic time series
Nadya Serebriakova, Andrew Tkachenko, Cole Johnston +2
The mass discrepancy problem, observed in high-mass stars within eclipsing binaries, highlights systematic differences between dynamical and evolutionary mass estimates, challengin…
Stellar ejection velocities from the binary supernova scenario: A comparison across population synthesis codes
Tom Wagg, David D. Hendriks, Mathieu Renzo +1
The vast majority of binary systems are disrupted at the moment of the first supernova, resulting in an unbound compact object and companion star. These ejected companion stars con…
