Age Determination of Six Intermediate-age SMC Star Clusters with HST/ACS
Katharina Glatt, Eva K. Grebel, Elena Sabbi +9
We present a photometric analysis of the star clusters Lindsay 1, Kron 3, NGC339, NGC416, Lindsay 38, and NGC419 in the Small Magellanic Cloud (SMC), observed with the Hubble Space…
Detection of new variable stars in the SMC cluster NGC 121
G. Fiorentino, R. Contreras, G. Clementini +5
New candidate variable stars have been identified in the Small Magellanic Cloud cluster NGC121, by applying both the image subtraction technique (ISIS, Alard 2000) and the Welch &…
An Accurate Age Determination for the SMC Star Cluster NGC121 with HST/ACS
K. Glatt, J. S. Gallagher, E. K. Grebel +8
As first Paper of a series devoted to study the old stellar population in clusters and fields in the Small Magellanic Cloud, we present deep observations of NGC121 in the F555W and…
Virgo cluster early-type dwarf galaxies with the Sloan Digital Sky Survey. III. Subpopulations: distributions, shapes, origins
Thorsten Lisker, Eva K. Grebel, Bruno Binggeli +1
From a quantitative analysis of 413 Virgo cluster early-type dwarf galaxies (dEs) with Sloan Digital Sky Survey imaging data, we find that the dE class can be divided into multiple…
Virgo cluster early-type dwarf galaxies with the Sloan Digital Sky Survey. II. Early-type dwarfs with central star formation
Thorsten Lisker, Katharina Glatt, Pieter Westera +1
Despite the common picture of an early-type dwarf (dE) as a quiescent galaxy with no star formation and little gas, we identify 23 dEs that have blue central colors caused by recen…
