The pulsating DA white dwarf PG2303+243 revisited
An analysis of about 27 h of fast photometry of the cool ZZ Ceti white dwarf PG2303+243 reveals (1) the presence of many modes (as many as 22), some of them of...

PublicaciónThe search for radial velocity variations in rapidly oscillating AP stars using the Fabry-Perot Interferometric Stellar Oscillation Spectrometer (FP-ISOS)Radial velocity measurements were taken of a group of Ap stars using an improved FP-ISOS. Observations were made using the 1.5m TCS on Tenerife in May 1987 and...

PublicaciónTime-resolved photometry of BN and CU Cancri, two delta Scuti stars in the Praesepe cluster. Fourth photometry campaign of the STEPHI networkThe fourth photometry campaign of the Stellar photometry International (STEPHI) network was carried out in January 1992. On this occasion, the delta Scuti-like...
