From binary systems to the evolution of the most massive stars
Life channels and fate of the most massive stars
My doctoral research focuses on the impact of rapid rotation on the computation of fundamental stellar parameters. In particular, I study how surface gradients in effective temperature — arising from rotational distortion and gravity darkening — introduce systematic biases in spectroscopic analyses. These effects lead to inaccurate parameter estimates when spherical symmetry is assumed. By incorporating 3D geometry and non-spherical configurations, I aim to establish a physically consistent framework for deriving the properties of rapidly rotating massive stars.
Physical Parameters of the Low-Mass Eclipsing Binary ASAS J052919-1617.3
In my MSc thesis I characterized the low-mass eclipsing binary ASAS J052919-1617.3 by combining calibrated and differential photometry with spectroscopy. I produced multi-filter light curves and obtained precise radial velocity measurements, performing a joint analysis with PHOEBE to derive robust fundamental parameters. I standardized the full data reduction pipeline, culminating in an MSc thesis awarded with the Maximum Grade in Spain.
Photometric Observations of Eclipsing Binary Star Systems
My undergraduate thesis established my entry into stellar astrophysics. I developed custom software for the observation and photometric reduction of light curves, including calibration, differential photometry, and basic quality control. Applied these tools to two binary systems, deriving their orbital periods and estimating preliminary physical parameters from the variability patterns. This work provided a reproducible analysis framework and an initial characterization of both systems.
