NGC 602 Environment, Kinematics and Origins
L. Nigra, J. S. Gallagher, L. J. Smith +3
The young star cluster NGC 602 and its associated HII region, N90, formed in a relatively isolated and diffuse environment in the Wing of the Small Magellanic Cloud. Its isolation…
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…
Holmberg Ix: The Nearest Young Galaxy
E. Sabbi, J. S. Gallagher, L. J. Smith +2
Deep images taken with the Wide Field Channel of the Advanced Camera for Surveys on board the Hubble Space Telescope provide the basis for study the resolved stellar population of…
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…
