A search for new symbiotic stars in the Milky Way: Using machine learning techniques applied to photometric databases
V. Contreras Rojas, M. Jaque Arancibia, C. E. Ferreira Lopes +8
Symbiotic stars (SySts) are interacting binaries composed of a red giant transferring material to a hot compact star, typically a white dwarf. Although only about 300 systems are c…
Skykatana: a scalable framework to construct sky masks for the Vera Rubin Observatory and large astronomical surveys
Claudio Lopez, Emilio Donoso, Mariano Javier de L. Dominguez Romero
Modern wide-field surveys require robust spatial masks to excise bright-star halos, bleed trails, poor-quality regions, and user-defined geometry at scale. We present Skykatana, an…
Searching for lambda Boo stars in binary systems
J. Alacoria, C. Saffe, A. Collado +7
Our goal is to find new candidate lambda Boo stars that belong to binary systems. A detailed abundance determination of some candidates could confirm their true lambda Boo nature,…
Strong signature of right-handed circularly polarized photoionization close to the cyclotron line in the atmosphere of magnetic white dwarfs
René D. Rohrmann
Magnetic fields break the symmetry of the interaction of atoms with photons with different polarizations, yielding chirality and anisotropy properties. The dependence of the absorp…
The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy
R. K. Saito, M. Hempel, J. Alonso-García +143
The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…
A numerical code for the analysis of magnetic white dwarf spectra that includes field effects on the chemical equilibrium
Matías Vera-Rueda, René D. Rohrmann
We present a new magnetic-atmosphere model code for obtaining synthetic spectral fluxes of hydrogen-rich magnetic white dwarfs. To date, observed spectra have been analyzed with mo…
