A continuous population of variable stars up to about 1.5 mag above the horizontal branch?
L. Baldacci, G. Clementini, E. V. Held +2
Increasing samples of pulsating variable stars populating the classical instability strip from the horizontal branch to a few magnitudes brighter are being found in several Local G…
The near-IR luminosity-metallicity relationship for dwarf irregular galaxies
Ivo Saviane, R. Riegerbauer, E. V. Held +6
We briefly describe our on-going investigation of the near-IR luminosity-metallicity relationship for dwarf irregular galaxies in nearby groups of galaxies. The motivations of the…
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…
Clues on the evolution of the Carina dwarf spheroidal galaxy from the color distribution of its red giant stars
L. Rizzi, E. V. Held, G. Bertelli +1
The thin red giant branch (RGB) of the Carina dwarf spheroidal galaxy appears at first sight quite puzzling and seemingly in contrast with the presence of several distinct bursts o…
RR Lyrae and short-period variable stars in the dwarf irregular galaxy NGC 6822
G. Clementini, E. V. Held, L. Baldacci +1
We report the discovery of a large number of short-period variable stars in the dwarf irregular galaxy NGC6822, based on deep time-series imaging carried out with the ESO Very Larg…
