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 . Dif…

Line-driven Radiative Winds in B-Supergiants: Bridging the Gap between Fast and Slow m-CAK Solutions

Matías 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…

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…

Evolution of rotating massive stars adopting a newer, self-consistent wind prescription at SMC metallicity

Alex Camilo Gormaz-Matamala, Jorge Cuadra, Sylvia Ekström +3

We use Geneva-evolution-code to run evolutionary tracks for stellar masses ranging from to at SMC metallicity (). We upgrade the recipe for stellar win…

Evolution of massive stars with new hydrodynamic wind models

A. C. Gormaz-Matamala, M. Curé, G. Meynet +3

Here we present evolutionary models for a set of massive stars, introducing a new prescription for the mass-loss rate obtained from hydrodynamical calculations in which the wind ve…

Revisiting Viscous Transonic Decretion Disks of Be Stars

Michel Curé, Rodrigo Meneses, Ignacio Araya +4

In the context of Be stars, we restudied the viscous transonic decretion disk model of these stars. This model is driven by a radiative force due to an ensemble of optically-thin l…

Application limit of the photocentre displacement to fundamental stellar parameters of fast rotators -- Illustration on the edge-on fast rotator Regulus

M. Hadjara, R. G. Petrov, S. Jankov +16

Differential Interferometry allows to obtain the differential visibility and phase, in addition to the spectrum. The differential phase contains important information about the str…

New self-consistent wind parameters fitting optical spectra of O-type stars observed with HERMES spectrograph

Alex C. Gormaz-Matamala, Michel Curé, Alex Lobel +5

We perform spectral fitting for a set of O-type stars based on self-consistent wind solutions, which provide mass-loss rate and velocity profiles directly derived from the initial…

Automatic algorithm to obtain values via Fourier Transform in BeSOS database

Martín Solar, Catalina Arcos, Michel Curé +2

Be stars are found to rotate close to their critical rotation and therefore they are considered as an important laboratory of study for stellar rotation. In this context, we obtain…

New hydrodynamic solutions for line-driven winds of hot massive stars using Lambert -function

Alex C. Gormaz-Matamala, Michel Curé, D. John Hillier +3

Hot massive stars present strong stellar winds that are driven by absorption, scattering and re\-emission of photons by the ions of the atmosphere (\textit{line-driven winds}). A b…

Resolving the kinematics of the disks around Galactic B[e] supergiants

Grigoris Maravelias, Michaela Kraus, Lydia S. Cidale +4

B[e] Supergiants are luminous evolved massive stars. The mass-loss during this phase creates a complex circumstellar environment with atomic, molecular, and dusty regions usually f…

Limb-Darkened Radiation-Driven Winds from Massive Stars

Michel Curé, Lydia Cidale, Diego F. Rial

We calculated the influence of the limb-darkened finite disk correction factor in the theory of radiation-driven winds from massive stars. We solved the 1-D m-CAK hydrodynamical eq…
