Star Counts in the Globular Cluster Omega Centauri. I. Bright Stellar Components
V. Castellani, A. Calamida, G. Bono +8
We present an extensive photometry on HB, RGB, and MSTO stars in Omega Cen. The central regions of the cluster were covered with a mosaic of F435W, F625W, and F658N-band data colle…
A pulsational distance to Omega Centauri based on Near-Infrared Period-Luminosity relations of RR Lyrae stars
M. Del Principe, A. M. Piersimoni, J. Storm +15
We present new Near-Infrared (J,K) magnitudes for 114 RR Lyrae stars in the globular cluster Omega Cen (NGC 5139) which we combine with data from the literature to construct a samp…
SN 2005cs in M51 I. The first month of evolution of a subluminous SN II plateau
A. Pastorello, D. Sauer, S. Taubenberger +16
Early time optical observations of supernova (SN) 2005cs in the Whirlpool Galaxy (M51), are reported. Photometric data suggest that SN 2005cs is a moderately under-luminous Type II…
B, V, I photometry of the complete sample of 23 Cepheids in the field of NGC 1866
I. Musella, V. Ripepi, E. Brocato +8
We present the result of BVI photometry, obtained by using FORS@VLT, of the Cepheids present in the field of the Large Magellanic Cloud cluster NGC 1866. We found the 22 known vari…
Weak homology of elliptical galaxies
G. Bertin, L. Ciotti, M. Del Principe
We start by studying a small set of objects characterized by photometric profiles that have been pointed out to deviate significantly from the standard R^{1/4} law. For these objec…
