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…
Hidden Figures of Globular Clusters: Integrated Stellar Populations Impacted by Hot Subdwarfs
Thayse A. Pacheco, Paula R. T. Coelho, Lucimara P. Martins +8
Globular clusters (GCs) are fundamental for understanding the integrated light of old stellar populations and galaxy assembly processes. However, the role of hot, evolved stars, su…
A grid of Non-LTE line-blanketed atmosphere structures and synthetic spectra for subdwarfs
Thayse A. Pacheco, Ronaldo S. Levenhagen, Marcos P. Diaz +1
We present an update of the grid of detailed atmosphere models and homogeneous synthetic spectra for hot, high-gravity subdwarf stars. High-resolution spectra and synthetic photome…
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…
A Grid of Synthetic Spectra for Subdwarfs: Non-LTE line-blanketed atmosphere models
Thayse A. Pacheco, Marcos P. Diaz, Ronaldo S. Levenhagen +1
A new grid of detailed atmosphere model spectra for hot and moderately cool subdwarf stars is presented. High-resolution spectra and synthetic photometry are calculated in the rang…
GALExtin: An alternative online tool to determine the interstellar extinction in the Milky Way
Eduardo B. Amores, Ricardo M. Jesus, Andre Moitinho +6
Estimates of interstellar extinction are essential in a broad range of astronomical research. In the last decades, several maps and models of the large scale interstellar extinctio…
