Distance Scale, Variable Stars and Stellar Populations in Local Group Galaxies
G. Clementini
We present an overview of our study of the short period variable stars in the Large Magellanic Cloud, and in the dwarf galaxies Fornax, Leo I, and NGC 6822. Light curves are presen…
NGC6822: short period variable stars, stellar population and distance scale
L. Baldacci, L. Rizzi, G. Clementini +2
Results are presented on a study of the short period variable stars in the dwarf irregular galaxy NGC6822. We observed an almost uniformely populated classical instability strip fr…
Variable stars as tracers of stellar populations in Local Group galaxies: Leo I and NGC 6822
L. Baldacci, F. Matonti, L. Rizzi +5
Results are presented of a study of the variable star populations in the dwarf spheroidal galaxy Leo I and in the dwarf irregular galaxy NGC 6822, based on time series photometry o…
Distance scale and variable stars in Local Group Galaxies: LMC and Fornax
M. Maio, L. Baldacci, G. Clementini +10
We briefly review our photometric and spectroscopic study of RR Lyrae variable stars in the bar of the Large Magellanic Cloud (LMC), that allowed us to reconcile the so-called "sho…
Variable Stars in the LMC: the Photometric Catalogue
M. Maio, G. Clementini, A. Bragaglia +3
New B, V, I photometry was obtained for a sample of 152 variables (125 RR Lyrae's, 4 anomalous Cepheids, 11 classical Cepheids, 11 eclipsing binaries and a delta Scuti star) in two…
NGC6822: detection of variable stars with ISIS2.1
L. Baldacci, G. Clementini, E. V. Held +1
Preliminary results on the detection of a conspicuous number of variable stars in the dwarf irregular galaxy NGC 6822 are presented. We stress the need for packages specifically de…
