Lithium-rich M-dwarfs at the ZAMS: Evidence for planetary engulfment?
R. D. Jeffries, R. J. Jackson, I. Baraffe
We identify 6 early M-dwarfs, in 3 open clusters (NGC 2451a, Blanco 1 and NGC 2516) at ages of 50-200 Myr, that are anomalously enriched in lithium compared with Li-depleted siblin…
Testing the reliability of magnetic field strength measurements for M dwarfs
I. Amateis, O. Kochukhov, A. Hahlin
M dwarfs host strong magnetic fields that can be measured using several complementary techniques. However, the impact of key methodological choices on Zeeman broadening diagnostics…
V446 Cephei: a Cep pulsator in a multiple system
A. Moharana, J. Southworth, K. Pavlovski +7
Cep stars in eclipsing binary (EB) systems give us an opportunity to put observational constraints on their structure and stellar parameters. We present a comprehensive analys…
X-Shooting ULLYSES: Massive stars at low metallicity XV. On the metallicity dependence of B-supergiant mass-loss rates
O. Verhamme, J. O. Sundqvist, A. de Koter +21
Context. For stellar evolution models we rely on mass-loss rate prescriptions that show features that lack empirical confirmation, such as the bi-stability jump. This jump is an in…
Near-infrared spectroscopy of RS Ophiuchi in 2021: the calm, the storm, and the abatement
C. E. Woodward, A. Evans, D. P. K. Banerjee +4
We present near-infrared (NIR) observations of the 2021 eruption of the recurrent nova RS Ophiuchi. The dataset provides both pre- and post-eruption perspectives on the eruption, a…
X-Shooting ULLYSES: Massive stars at low metallicity XIV. Properties of SMC late-O and B supergiants reveal the metallicity dependence of winds in the Magellanic Clouds
T. Alkousa, P. A. Crowther, J. M. Bestenlehner +10
Considering the physics of radiation-driven winds of massive stars, the wind properties should depend on the metal content of the stellar atmosphere. Therefore, studying the winds…
