Sobre mi investigación: Está centrada en el estudio de acreción en discos protoplanetarios, incluyendo compañeros subestelares. Y además estudio protoenanas marrones a partir de datos de ALMA.

About my research:My thesis research focuses on the observations of Post Common Envelope Binaries that consist in a White Dwarf + a massive main sequence FGK star. Those are the progenitors systems of the two main channels in which the Supernova Ia can be produced (single and double - degenerated channels). Our aim is try to do a general consensus on the pathways leading to the SN Ia explosion.

About my research: My research is focused on circumstellar disks, and using observations to constrain the methods of planet formation within them, either around young stars or evolved binaries, and I use some of the newest instruments and techniques available to achieve this.

About my research: I'm a M.Sc. Astrophysics student, working within the Compact Binary Group in the Institute. I'm currently doing my thesis on "Testing the third body explanation for eclipse timing variations in PCEBs" with the aim of explaining the origin of the variations observed in this system. The specific goal of my thesis is to obtain the orbital parameters of possible planetary orbits around the binary star system RR Cae, via statistical methods (specifically MCMC), and determining the stability of the orbit of this possible planet.

About my research: My thesis project focus on the gravitational lens effect at different scales in the Universe. At small scale, I study microlensing light curves to detect exoplanets. At large scale, I search for microlensing effect in lensed quasar systems to study the inner structure of the quasar and also the lensing galaxy. At a larger scale I perform dynamical analysis of lensing galaxy groups.

Ph.D. (c) in Astrophysics, Universidad de Valparaíso, Chile. (MSc. Astrophysics 2013-2014)
Research Area: Mass-loss rate, Be stars, Stellar Winds.
email: katalina.arcos at uv.cl

About my research: My thesis research project is focused on the study of the variability of Be stars, their mass-loss rate, and the connection with the disk formation. In order to do this, we are creating the BeSOS catalogue, and we are working on reproducing line profile models in agreement with the observations of these stars

Ph.D. (c) in Astrophysics, Universidad de Valparaíso, Chile.
Research Area: Massive Stars, Stellar Winds, Hydrodynamics, Radiative Transport
email:  ignacio.araya at uv.cl

About my research: My research is focused on massive stars, mainly in their stellar winds. We use both hydrodynamic and radiative transfer codes to model the available observational data of these stars.
