On the newly discovered Canes Venatici II dSph galaxy
C. Greco, M. Dall'Ora, G. Clementini +11
We report on the detection of variable stars in the Canes Venatici II (CVn II) dwarf spheroidal galaxy, a new satellite of the Milky Way recently discovered by the Sloan Digital Sk…
NGC 2419: an "intergalactic wanderer" or a simple Galactic Globular Cluster?
M. Di Criscienzo, C. Greco, M. Dall'Ora +8
We have carried out a new photometric study of the remote Galactic globular cluster NGC 2419, using proprietary and archive B,V,I time-series CCD photometry of the cluster, that al…
Pulsational models of BL Her stars
M. Di Criscienzo, M. Marconi, F. Caputo +1
We present an updated and homogeneous pulsational scenario for a wide range of stellar parameters typical of BL Her stars i.e., Population II Cepheids with periods shorter than 8 d…
Theoretical fits of the δCephei light, radius and radial velocity curves
Giovanni Natale, Marcella Marconi, Giuseppe Bono
We present a theoretical investigation of the light, radius and radial velocity variations of the prototype Cephei. We find that the best fit model accounts for luminosity and…
Variable Stars in the Newly Discovered Milky Way Dwarf Spheroidal Satellite Canes Venatici I
Charles Kuehn, Karen Kinemuchi, Vincenzo Ripepi +11
We have identified 23 RR Lyrae stars and 3 possible Anomalous Cepheids among 84 candidate variables in the recently discovered Canes Venatici I dwarf spheroidal galaxy. The mean pe…
Synthetic properties of bright metal-poor variables. II. BL Her stars
M. Di Criscienzo, F. Caputo, M. Marconi +1
We investigate the properties of the so-called BL Her stars, i.e., Population II Cepheids with periods shorter than 8 days, using updated pulsation models and evolutionary tracks c…
