Clumping and X-Rays in cooler B supergiant stars

Matheus Bernini-Peron, Wagner L. F. Marcolino, Andreas A. C. Sander +6

B supergiants (BSGs) are evolved stars with effective temperatures between 10 to 30 kK and are important to understand massive star evolution. Located on the edge of the line-drive…

A partially stripped massive star in a Be binary at low metallicity: A missing link towards Be X-ray binaries and double neutron star mergers

V. Ramachandran, J. Klencki, A. A. C. Sander +4

Standard binary evolutionary models predict a significant population of core helium-burning stars that lost their hydrogen-rich envelope after mass transfer via Roche-lobe overflow…

X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description

Jorick S. Vink, A. Mehner, P. A. Crowther +78

Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…

Spectroscopic and evolutionary analyses of the binary system AzV 14 outline paths toward the WR stage at low metallicity

D. Pauli, L. M. Oskinova, W. -R. Hamann +16

The origin of the observed population of Wolf-Rayet (WR) stars in low-metallicity (low-Z) galaxies, such as the Small Magellanic Cloud (SMC), is not yet understood. Standard, singl…

Massive star feedback in the Magellanic Clouds and the tidal Bridge

Varsha Ramachandran

Massive stars have far-reaching feedback effects that alter the surrounding environment on local, global, and cosmic scales. Spectral analyses of massive stars with adequate stella…

Bringing Stellar Evolution & Feedback Together: Summary of proposals from the Lorentz Center Workshop, 2022

Sam Geen, Poojan Agrawal, Paul A. Crowther +34

Stars strongly impact their environment, and shape structures on all scales throughout the universe, in a process known as ``feedback''. Due to the complexity of both stellar evolu…

The temperature dependency of Wolf-Rayet-type mass loss: An exploratory study for winds launched by the hot iron bump

A. A. C. Sander, R. R. Lefever, L. G. Poniatowski +3

CONTEXT: The mass loss of He-burning stars, which are partially or completely stripped of their outer hydrogen envelope, is a catalyst of the cosmic matter cycle and decisive ingre…
