A new search for variable stars in the globular cluster NGC 6366
A. Arellano Ferro, Sunetra Giridhar, V. Rojas Lopez +3
New CCD photometry of NGC 6366 has lead to the discovery of some variable stars. Two possible Anomalous Cepheids (or Pop II Cepheids), three long period variables, one SX Phe and o…
CCD Photometry of the globular cluster NGC 5466. RR Lyrae light curve decomposition and the distance scale
A. Arellano Ferro, V. Rojas Lopez, Sunetra Giridhar +1
We report the results of CCD V and r photometry of the globular cluster NGC 5466. The difference image analysis technique adopted in this work has resulted in accurate time series…
Variable stars in the open cluster NGC 6791 and its surrounding field
F. De Marchi, E. Poretti, M. Montalto +7
Aims: This work presents a high--precision variability survey in the field of the old, super metal-rich open cluster NGC 6791. Methods: The data sample consists of more than 75,000…
A new search for planet transits in NGC 6791
M. Montalto, G. Piotto, S. Desidera +12
Context. Searching for planets in open clusters allows us to study the effects of dynamical environment on planet formation and evolution. Aims. Considering the strong dependence o…
CCD Photometry of the globular cluster M2. RR Lyrae physical parameters and new variables
C. Lazaro, A. Arellano Ferro, M. J. Arevalo +3
We report the results of CCD V and R photometry of the RR Lyrae stars in M2. The periodicities of most variables are revised and new ephemerides are calculated. Light curve decompo…
A multisite photometric campaign on the Pre-Main-Sequence delta Scuti pulsator IP Per
V. Ripepi, S. Bernabei, M. Marconi +18
We present the results of a photometric multisite campaign on the Scuti Pre-Main-Sequence star IP Per. Nine telescopes have been involved in the observations, with a total of a…
