The Globular Cluster NGC 5286. I. A New CCD BV Color-Magnitude Diagram
M. Zorotovic, M. Catelan, M. Zoccali +5
We present BV photometry of the Galactic globular cluster NGC 5286, based on 128 V frames and 133 B frames, and covering the entire face of the cluster. Our photometry reaches almo…
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 &…
I Zw 18 revisited with HST/ACS and Cepheids: New Distance and Age
A. Aloisi, G. Clementini, M. Tosi +9
We present new V and I-band HST/ACS photometry of I Zw 18, the most metal-poor blue compact dwarf (BCD) galaxy in the nearby universe. It has been argued in the past that I Zw 18 i…
Very metal poor Classical Cepheids: variables in IZw18
G. Fiorentino, M. Marconi, G. Clementini +5
In the framework of an ongoing ACS@HST project (HST program #10586, PI: Aloisi) we have obtained deep multi-color imaging of the very metal-poor Blue Compact Dwarf galaxy IZw18. Th…
A New Deep HST/ACS CMD of I Zw 18: Evidence for Red Giant Branch Stars
A. Aloisi, F. Annibali, J. Mack +8
We present results from new deep HST/ACS photometry of I Zw 18, the most metal-poor blue compact dwarf galaxy in the nearby universe. It has been previously argued that this is a v…
