The contribution of the color space in LSST-like photometry for the selection of extragalactic globular cluster candidates

Nicholas Schweder-Souza, Ana L. Chies-Santos, Rafael S. de Souza +16

Globular clusters (GCs) are excellent tracers of their host galaxies' evolutionary histories. Traditional methods for identifying GCs in galaxies rely on cuts over photometric cata…

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…

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…

Investigating three Sirius-like systems with SPHERE

R. Gratton, V. D'Orazi, T. A. Pacheco +61

Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…

A comparative analysis of the observed white dwarf cooling sequence from globular clusters

Fabíola Campos, P. Bergeron, A. D. Romero +8

We report our study of features at the observed red end of the white dwarf cooling sequences for three Galactic globular clusters: NGC\,6397, 47\,Tucanae and M\,4. We use deep colo…
