Variability and star formation in Leo T, the lowest luminosity star-forming galaxy known today
Gisella Clementini, Michele Cignoni, Rodrigo Contreras Ramos +5
We present results from the first combined study of variable stars and star formation history (SFH) of the Milky Way (MW) "ultra-faint" dwarf (UFD) galaxy Leo T, based on F606W and…
Variable stars in the globular cluster M28 (NGC 6626)
G. Prieto, M. Catelan, R. Contreras Ramos +3
We present a new search for variable stars in the Galactic globular cluster M28 (NGC 6626). The search is based on a series of BVI images obtained with the SMARTS Consortium's 1.3m…
Chemical and kinematical properties of BSSs and HB stars in NGC 6397
L. Lovisi, A. Mucciarelli, B. Lanzoni +4
We used three sets of high-resolution spectra acquired with the multifiber facility FLAMES at the Very Large Telescope of the European Southern Observatory to investigate the chemi…
The ancient stellar population of M32: RR Lyr Variable stars confirmed
G. Fiorentino, R. Contreras Ramos, E. Tolstoy +2
Using archival multi--epoch ACS/WFC images in the F606W and F814W filters of a resolved stellar field in Local Group dwarf elliptical galaxy M32 we have made an accurate Colour-Mag…
