Gaia FGK benchmark stars: Abundances of n-capture elements of the third version
S. Vitali, P. Jofré, L. Casamiquela +10
In the current era, in which an unprecedented wealth of data are available for the study of the Milky Way, Gaia benchmark stars (GBSs) have become an established reference and cali…
ISOSCELES Project: II. Modelling galactic B-type stars for fast and slow wind regimes
N. Machuca, M. Curé, I. Araya +5
Radiation-driven winds in B-type stars play a key role in their evolution, yet their hydrodynamical structure remains uncertain, particularly in evolved objects. While the classica…
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…
Radiation-driven stellar winds at the fast-slow transition: new hydrodynamic solutions
M. C. Fernandez, R. O. J. Venero, L. S. Cidale +2
Radiation-driven winds of massive stars can be described within the modified CAK theory, which parametrises the radiation force through three key quantities: , , and . D…
Photometric and spectroscopic variability of the blue supergiant rho Leo
V. A. Checha, A. Aret, I. Kolka +12
Context. The post-main-sequence evolution of massive stars remains poorly understood, particularly for blue supergiants. These objects play a crucial role in the dynamical and chem…
