Physics of Low Mass Stars, Exoplanets and Associated Instrumentation

In this line we deal mainly with the study of variability in stars of low and very low mass (dwarf M stars), including pulsations, as well as the study of exoplanetary systems and the development of suitable instrumentation for the observation of these systems.

During the last stages of its formation, variability in stars of low and very low mass is dominated by the phenomena of accretion of matter from a disk surrounding the star. But as the material begins to agglomerate disc , resulting in larger particles , the predominant cause of variability becomes magnetic type activity. This activity causes cold spots and flares , very similar to what we know in the Sun. Our ​​study of these stars is twofold : determine physical parameters of these stars and learn to characterize its variability, which can reach to mask traces of the planets revolving around them.
