Near-infrared spectroscopy of the LMC recurrent nova LMCN 1968-12a
A. Evans, D. P. K. Banerjee, T. R. Geballe +5
We have obtained near-infrared (m) spectra of the recurrent nova LMCN 1968-12a on two occasions during its 2024 August eruption. This is the first near-infrared spectro…
X-Shooting ULLYSES: Massive Stars at Low Metallicity X. Physical Parameters and Feedback of Massive Stars in the LMC N11 B Star-Forming Region
V. M. A. Gómez-González, L. M. Oskinova, W. -R. Hamann +23
Massive stars lead the ionization and mechanical feedback within young star-forming regions. The Large Magellanic Cloud (LMC) is an ideal galaxy for studying individual massive sta…
X-Shooting ULLYSES: Massive Stars at low metallicity IX: Empirical constraints on mass-loss rates and clumping parameters for OB supergiants in the Large Magellanic Cloud
O. Verhamme, J. Sundqvist, A. de Koter +16
Context. Current implementations of mass loss for hot, massive stars in stellar evolution models include a sharp increase in mass loss when blue supergiants become cooler than Teff…
Variability and stellar pulsation incidence in Am/Fm stars using TESS and Gaia data
Oliver Durfeldt-Pedros, Victoria Antoci, Barry Smalley +3
Aims. We aim to study chemically peculiar Am and Fm stars, distinguished by their unique abundance patterns, which are crucial for studying mixing processes in intermediate-mass st…
Evolving massive stars to core collapse with GENEC: Extension of equation of state, opacities and effective nuclear network
Adam Griffiths, Miguel-Á Aloy, Raphael Hirschi +6
Stars with initial mass above roughly 8 solar masses will evolve to form a core made of iron group elements at which point no further exothermic nuclear reactions between charged n…
Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC
T. Shenar, J. Bodensteiner, H. Sana +74
Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…
