PublicaciónLight curves of SDSS J100658.40+233724.4 (Southworth+, 2009)
We present the discovery and follow-up observations of eclipses of the cataclysmic variable star SDSS J100658.40+233724.4, fom which we determine the orbital...

PublicaciónLine intensities of SDSS HII regions (Pilyugin+, 2010)
Spectra of high-metallicity [12+log(O/H)>~8.2] HII regions, where oxygen auroral lines are measurable in both the O+ and O++ zones, have been extracted from the...

PublicaciónMapping magnetic activity indicators across the M dwarf domain
Stellar activity poses one of the main obstacles for the detection and characterisation of exoplanets around cool stars, as it can induce radial velocity (RV)...
