HST photometry of Sculptor group dwarf galaxies
Listed in IVOA Registry (Virtual Observatory)
We focus on the resolved stellar populations of one early-type and four transition-type dwarf galaxies in the Sculptor group, with the aim to examine the potential presence of population gradients and place constraints on their mean metallicities.
Description
We use deep Hubble Space Telescope images to construct color-magnitude diagrams, from which we select stellar populations that trace different evolutionary phases in order to constrain their range of ages and metallicities, as well as to examine their spatial distribution.
In addition, we use the resolved stars in the red giant branch in order to derive photometric metallicities.
