PublicaciónObservation of a variable, ZZ Ceti white dwarf: GD154
The ZZ Ceti stars form a class of variable white dwarfs: the hydrogen dominated atmosphere ones, which do pulsate in an instability strip in the effective...

PublicaciónOn the Characterization of GJ 504: A Magnetically Active Planet-host Star Observed by the Transiting Exoplanet Survey Satellite (TESS)
We present the results of the analysis of the photometric data collected in long- and short-cadence mode by the Transiting Exoplanet Survey Satellite for GJ 504...

PublicaciónOn the Metamorphosis of the Bailey Diagram for RR Lyrae Stars
We collected over 6000 high-resolution spectra of four dozen field RR Lyrae (RRL) variables pulsating either in the fundamental (39 RRab) or in the first...

PublicaciónOn the relation of the Duvall phase function to the upper layers on the convection zone
A method to obtain the Duvall phase function from the structure of a stellar model is presented. This can be a good tool for understanding the dependence of p...

PublicaciónPulsation in moderate rotating delta Scuti stars: The case of BN and BU CANCRI
The results reported in this paper concern two delta Scuties in the Praesepe cluster, namely BN Cnc and BU Cnc, observed during the 1992 STEPHI 4 campaign. Five...

PublicaciónRapid photometry of the Delta Scuti variable 63 Herculis and of the F 2V star HD 155543 - Observations and analysis of the time series
In this paper we report the results of simultaneous observations, using rapid continuous differential photometry, of the δ Scuti star 63 Her and of a normal...
