Near-Infrared Observations of RR Lyrae Variables in Centauri
M. Del Principe, A. M. Piersimoni, J. Storm +6
We present Near-Infrared (NIR) and -band observations for 181 RR Lyrae stars in the Galactic Globular Cluster Cen. The comparison between predicted and empirical slope…
Antlia: an outskirt Local Group Galaxy
Marco Castellani, Giuseppe Bono, Santi Cassisi +2
Deep (I,V-I) and (I,B-I) color-magnitude diagrams (CMDs) of the Antlia dwarf galaxy, based on Science Verification (SV) data collected with the FORS I camera on the ESO Very Large…
A new investigation on the Antlia Dwarf Galaxy
A. M. Piersimoni, G. Bono, M. Castellani +4
We present deep (I,V-I) and (I,B-I) color-magnitude diagrams (CMDs) of the Antlia dwarf galaxy, based on Science Verification (SV) data collected with the FORS I camera on the ESO…
Multifrequency observations of XTE J0421+560/CI Cam in outburst
F. Frontera, M. Orlandini, L. Amati +9
We report on two X-ray observations of the transient source XTE J0421+560 performed by BeppoSAX, and on a series of observations performed by the 0.7m Teramo-Normale Telescope. Out…
A photometric study of the field RR Lyrae stars AW Dra, AQ Lyr and CN Lyr
V. Castellani, A. Di Paolantonio, A. M. Piersimoni +1
We present CCD lightcurves for the three field RR Lyrae AQ Lyr, CN Lyr and AW Dra observed at the Teramo TNT telescope. Stellar temperatures have been derived from the observed mea…
