Position and photometry of stars in SDIG
Listed in IVOA Registry (Virtual Observatory)
We study the resolved stellar populations and derive the star formation history of the Sculptor dwarf irregular galaxy (SDIG), a gas-rich dwarf galaxy member of the NGC 7793 subgroup in the Sculptor group of galaxies.
Description
We constructed a colour - magnitude diagram (CMD) using archival observations from the Hubble Space Telescope/Advanced Camera for Surveys in order to examine the stellar content of SDIG, as well as the spatial distribution of stars selected within different stellar evolutionary phases.
We derived the star formation history of SDIG using a maximum-likelihood fit to the CMD.
