José Rodrigues

PhD student at Instituto de Astrofisica e Ciências do Espaço

My research focuses on discovering and characterizing exoplanets.

I completed my Master thesis, called “Searching for Neptunes and super-Earths with SOPHIE”, under the supervision of Pr. François Bouchy and Dr. Nathan Hara, at the Geneva Observatory.  I had to understand and correct the instrumental systematics of the SOPHIE spectrograph. Such correction allowed for the detection of new signals previously drowned in the instrumental noise.

My PhD subject is “Mitigate stellar activity to characterise Earth-size planets”, under the supervision of Dr. Susana Barros and Dr. Nuno Santos, at Instituto de Astrofisica e Ciências do Espaço, in Porto. With the new state-of-the-art instruments (such as ESPRESSO and CHEOPS), the limiting factor is not the instrumental noise anymore but the stellar activity. This challenge needs to be faced in order to take the detectability limits further.
