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…
Line-driven Radiative Winds in B-Supergiants: Bridging the Gap between Fast and Slow m-CAK Solutions
MatÃas Montesinos, Emil Zabala-Arroyo, Juan José Castro-Salgado +2
The modified Castor, Abbott, and Klein (m-CAK) theory predicts different wind regimes based on the line force parameter for changes in ionization () and the rotation parameter…
New self-consistent theoretical descriptions for mass-loss rates of O-type stars
F. Figueroa-Tapia, J. A. Panei, M. Curé +5
Massive O-type stars lose a significant fraction of their mass through radiation-driven winds, a process that critically shapes their evolution and feedback into the interstellar m…
ISOSCELES project: A grid-based quantitative spectroscopic analysis of massive stars
I. Araya, M. Curé, N. Machuca +4
Massive stars play a fundamental role in galactic evolution through their strong stellar winds, chemical enrichment, and feedback mechanisms. Accurate modelling of their atmosphere…
