The ACS LCID Project: RR Lyrae stars as tracers of old population gradients in the isolated dwarf spheroidal galaxy Tucana
Edouard J. Bernard, Carme Gallart, Matteo Monelli +9
We present a study of the radial distribution of RR Lyrae variables, which present a range of photometric and pulsational properties, in the dwarf spheroidal galaxy Tucana. We find…
Stellar Content and Recent Star Formation History of the Local Group Dwarf Irregular Galaxy IC1613
Edouard J. Bernard, Antonio Aparicio, Carme Gallart +2
We present resolved-star VI photometry of the Local Group dwarf irregular galaxy IC1613 reaching I~23.5, obtained with the wide-field camera at the 2.5m Isaac Newton Telescope. A f…
The ACS LCID Project: Variable Stars in Tucana and LGS3
Edouard J. Bernard
We present preliminary results concerning the search for short-period variable stars in Tucana and LGS3 based on very deep HST/ACS imaging. In the one chip per galaxy we studied so…
The Stellar Structures around Disk Galaxies
I. Drozdovsky, N. Tikhonov, A. Aparicio +6
We present a brief summary of our current results on the stellar distribution and population gradients of the resolved stars in the surroundings of ~50 nearby disk galaxies, observ…
