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…
Completing the Census of (Bright) Variable Stars in Galactic Globular Clusters
M. Catelan, H. A. Smith, B. J. Pritzl +15
We present a long-term project aimed at completing the census of (bright) variable stars in Galactic globular clusters. While our main aim is to obtain a reliable assessment of the…
The Carina dSph galaxy: where is the edge?
G. Bono, M. Monelli, A. R. Walker +13
Recent cosmological N-body simulations suggest that current empirical estimates of tidal radii in dSphs might be underestimated by at least one order of magnitude. To constrain the…
White Dwarfs in Omega Centauri: Preliminary Evidence
G. Bono, M. Monelli, P. B. Stetson +7
We present accurate and deep multiband B,R,Halpha data for the globular cluster Omega Cen collected with the Advanced Camera for Surveys on HST. The photometric catalogue includes…
HST Observations of the Main Sequence of M4
H. B. Richer, G. G. Fahlman, J. Brewer +8
This paper presents new results from a photometric study of the main-sequence stars in M4, the closest globular cluster to the sun. Multi-field, multi-epoch observations at approxi…
Type Ia Supernovae and the Value of the Hubble Constant
Brad K. Gibson, Chris B. Brook
The methodology involved in deriving the Hubble Constant via the calibration of the corrected peak luminosities of Type Ia supernovae (SNe) is reviewed. We first present a re-analy…
