PublicaciónA novel framework for semi-Bayesian radial velocities through template matching
Context. The ability to detect and characterise an increasing variety of exoplanets has been made possible by the continuous development of stable, high...

PublicaciónA pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 characterized with CHEOPS
We report the discovery and characterization of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in the...

PublicaciónA PCA approach to stellar effective temperatures
Context. The derivation of the effective temperature of a star is a critical first step in a detailed spectroscopic analysis. Spectroscopic methods suffer from...

PublicaciónA Photometric Diagnostic to Aid in the Identification of Transiting Extrasolar Planets
One of the obstacles in the search for exoplanets via transits is the large number of candidates that must be followed up, few of which ultimately prove to be...

PublicaciónA photometric study of the hot exoplanet WASP-19b
Context. The sample of hot Jupiters that have been studied in great detail is still growing. In particular, when the planet transits its host star, it is...

PublicaciónA planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776
We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54 ± 0.03 M ☉)...

PublicaciónA Possible Third Component in the L Dwarf Binary System DENIS-P J020529.0-115925 Discovered with the Hubble Space Telescope
We present results showing that the multiple system DENIS-P J020529.0-115925 is likely to be a triple system of very low mass stars and brown dwarfs. The...
