How fast is the fastest-rotating O-type star in the Galaxy?
M. Curé, R. S. Levenhagen, D. Turis-Gallo +4
{Rapid rotation distorts massive stars, making parameters from spherical models inclination-dependent. We studied these effects in the extreme Galactic O-type runaway LAMOST J04064…

Multi epoch spectroscopic variability of the B supergiant HD75149
J. Chamoun-Contreras, C. Arcos, N. Machuca +6
Massive stars continuously enrich the surrounding interstellar medium by supplying it with stellar material driven by their powerful winds. B supergiant stars (BSGs) in particular…

Unveiling stellar spin: Determining inclination angles in Be stars
D. Turis-Gallo, M. Curé, R. S. Levenhagen +3
The physical properties of stellar atmospheres in rapidly rotating massive stars, such as Be stars, are critical to understanding their evolution and their role as progenitors of s…
