Variable stars in the Fornax dSph Galaxy. II. Pulsating stars below the horizontal branch
Ennio Poretti, Gisella Clementini, Enrico V. Held +6
We have carried out an intensive survey of the northern region of the Fornax dwarf spheroidal galaxy with the aim of detecting the galaxy's short--period pulsating stars (P<0.25 da…
The evolved stars of Leo II dSph galaxy from near-infrared UKIRT/WFCAM observations
M. Gullieuszik, E. V. Held, L. Rizzi +3
We present a study of the evolved stellar populations in the dwarf spheroidal galaxy LeoII, based on JHKs observations obtained with the near-infrared array WFCAM at the UKIRT tele…
Resolving Stellar Populations outside the Local Group: MAD observations of UKS2323-326
M. Gullieuszik, L. Greggio, E. V. Held +14
We present a study aimed at deriving constraints on star formation at intermediate ages from the evolved stellar populations in the dwarf irregular galaxy UKS2323-326. These observ…
The blue plume population in dwarf spheroidal galaxies: young stellar population or genuine blue stragglers?
Y. Momany, E. V. Held, I. Saviane +3
In the context of dwarf spheroidal galaxies it is hard to firmly disentangle a genuine Blue Stragglers (BSS) population from a normal young main (MS) sequence. This difficulty is p…
Near-Infrared photometry of carbon stars in the Sagittarius dwarf irregular galaxy and DDO 210
M. Gullieuszik, M. Rejkuba, M. R. Cioni +2
We investigate the intermediate-age asymptotic giant branch stellar population of two Local Group dwarf irregular galaxies to characterize their carbon star population in near-infr…
Variable stars in the Fornax dSph Galaxy. I. The Globular Cluster Fornax 4
C. Greco, G. Clementini, M. Catelan +8
Variable stars have been identified for the first time in Fornax 4, the globular cluster located near the center of the Fornax dwarf spheroidal galaxy. By applying the image subtra…
