My current research with prof. Michel Curé, is about the study of stellar rotations in massive stars applying deconvolution methods for non-spherical distributions in the unit sphere of observation. Our analysis is made by using apparent rotational velocities values taken from the literature, e.g., vizier.

I’m currently working with prof. Catalina Arcos on the detections of changes in the spectra of Be stars observed at different disk phases. During the last years, I learned to carry out echelle spectroscopic observations and the corresponding data reduction, use stellar model atmospheres and contrast it with photometric and spectroscopic data and determine equivalent widths and radial velocities using Gaussian/Voigt distributions.

My work (leaded by prof. Michel Curé) is focuses in obtain mass-loss rates of massive stars by varying theoretical densities at the stellar surface using the Hydwind and AKD27 hydrodynamical codes. These solutions will be used as input in the Fastwind code in order to obtain synthetic spectra and to compare them with observations. As final result we expect to generate a grid of theoretical models describing the upper part of the HR Diagram.

I’m participating in one part of prof. Michel’s project which is about to create a grid of Hydwind+Fastwind models for different stellar (Teff, Logg,R/Rsun) and wind (mass-loss rate and terminal velocity) parameters. I’m learning (deep) neural networks to create a program which will be able to identify/select the most appropriate model (from our grid) from a set of spectral lines obtained via observations. Once the model is determined, we will know the stellar and wind parameters.

I just started to work with prof. Catalina Arcos. Currently, I’m using an automated program to obtain measurements on observed lines in optical spectra of a sample of Be stars.
