Unraveling the birthplaces of NGC2070's massive stars, tracked with MUSE and revealed with JWST
N. Castro
The formation of massive O-type stars cannot be simply explained as a scaled-up version of the accretion mechanisms observed in lower-mass stars. Understanding these processes nece…
Dynamical vs Supernova Acceleration of OB Stars in the Small Magellanic Cloud
M. S. Oey, J. Dorigo Jones, G. D. Phillips +3
We use the RIOTS4 sample of SMC field OB stars to determine the origin of massive runaways in this low-metallicity galaxy using Gaia proper motions, together with stellar masses ob…
Strong Variability in AzV 493, an Extreme Oe-Type Star in the SMC
M. S. Oey, N. Castro, M. Renzo +11
We present 18 years of OGLE photometry together with spectra obtained over 12 years, revealing that the early Oe star AzV 493 shows strong photometric (Delta I < 1.2 mag) and spect…
MUSE 3D spectroscopy of BA-type supergiants in NGC 300
Gemma González-Torà, Miguel A. Urbaneja, Norbert Przybilla +4
We present the results obtained using spectroscopic data taken with the intermediateresolution Multi Unit Spectroscopic Explorer (MUSE) of B and A-type supergiants and bright giant…
Classical OBe Stars as Post-Supernova Runaways: Confirming Binary Origins
Matthew M. Dallas, M. S. Oey, Norberto Castro
Massive binaries play an important role in fields ranging from gravitational wave astronomy to stellar evolution. We provide several lines of evidence that classical OBe stars in t…
Stellar mergers as the origin of the blue main-sequence band in young star clusters
Chen Wang, Norbert Langer, Abel Schootemeijer +10
Recent high-quality Hubble Space Telescope (HST) photometry shows that the main sequences (MS) stars of young star clusters form two discrete components in the color-magnitude diag…
