Multi-Dimensional MHD simulations of young Core-Collapse Supernova Remnants
C. J. K. Larkin, J. Mackey, B. Reville +3
Supernova remnants (SNRs) play a central role in shaping the interstellar medium. Core-Collapse Supernova (CCSN) progenitors are massive stars, which produce a dense circumstellar…
EWOCS-V: Is Wd1-72 a recent post-interaction WR+O binary?
C. J. K. Larkin, J. Mackey, H. Jin +14
The evolutionary origin of Wolf-Rayet (WR) stars at Solar metallicity is unclear. Single-star evolution from massive O stars, possibly via a Luminous Blue Variable phase, is challe…
Investigating dusty Red Supergiant outflows in Westerlund 1 with 3D Hydrodynamic simulations
C. J. K. Larkin, J. Mackey, T. J. Haworth +1
Recent JWST observations towards Westerlund 1 revealed extensive nebular emission associated with the cluster. Given the age of the region and proximity of that material to massive…
X-Shooting ULLYSES: Massive stars at low metallicity. IV. Spectral analysis methods and exemplary results for O stars
A. A. C. Sander, J. -C. Bouret, M. Bernini-Peron +26
CONTEXT: The spectral analysis of hot, massive stars is a fundamental astrophysical method to obtain their intrinsic properties and their feedback. Quantitative spectroscopy for ho…
X-Shooting ULLYSES: Massive Stars at low metallicity II. DR1: Advanced optical data products for the Magellanic Clouds
H. Sana, F. Tramper, M. Abdul-Masih +34
Using the medium resolution spectrograph X-shooter, spectra of 235 OB and Wolf-Rayet (WR) stars in sub-solar metallicity environments have been secured. [...]This second paper focu…
