Descripción
We present deep and accurate photometry (F435W, F625W, F658N) of the
Galactic Globular Cluster omega Cen collected with the Advanced Camera
for Surveys (ACS) on board the Hubble Space Telescope (HST). We
identified ≈ 6,500 white dwarf (WD) candidates and compared their
radial distribution with that of Main Sequence (MS) stars. We found a
mild evidence that young WDs ( 0.1 ≲ t ≲ 0.6 Gyr) are less
centrally concentrated when compared to MS stars in the magnitude range
25 < F435W < 26.5.
