Sobre mi investigación: Mi investigación se centra en el estudio de variabilidad de las estrellas Be, los parámetros de disco y estelares, su tasa de pérdida de masa y la conexión con la formación del disco. Para hacer esto, creamos el sitio web de BeSOS: https://besos.ifa.uv.cl que contiene espectros HR reducidos de las estrellas del sur de Be observadas con el espectrógrafo PUCHEROS. Restringimos los parámetros estelares de 71 estrellas Be usando atmósferas de modelado estelar. Las velocidades de rotación proyectadas se obtuvieron para todos los espectros, así como EW, DPS, V / R en la línea Halpha.

About my research: My work is focused on the simulation of close compact binary stars, and the comparison of these with observational data. The aim is to achieve a better understanding of the common envelope phase, a phase that most of these stars undergo, which is a clue for understanding the evolution of some of the most interesting objects in the universe, such as type Ia supernovae, cataclysmic variables, or close double white dwarfs, to name a few. In addition, the recently suggested possibility of planets around evolved close compact binaries has raised the interest in knowing how they might have formed.

About my research: My main research interests deal with accretion onto supermassive black holes and the study of the entire central engine of Active Galactic Nuclei (AGN). I use X-ray data, mainly from XMM-Newton, Chandra and NuSTAR space observatories, as well as optical and IR data taken with telescopes in northern Chile to map the structure of the accretion disc, X_ray corona and the molecular dusty obscurer. I also study accretion behind thick layers of gas, to better understand the spectrum of this important phase of black hole growth and better interpret the cosmic X-ray background

About my research: My research focuses on understanding the origin and evolution of extreme horizontal branch stars, by probing the internal structure of pulsating hot subdwarf stars through the interpretation of their frequency spectra. In order to analyse their pulsation spectra I am using the high-resolution time series photometric and spectroscopic data from ground based and space telescopes, like Kepler. By confronting the observed frequency spectrum with the theoretical models I am able to constrain crucial parameters in order to backtrace the evolution of hot subdwarf stars. In addition to asteroseismology I also study close binary stellar evolution, as well as extrasolar planets around evolved stars.
