Abstract:
We present a study of the evolved stellar populations in the dwarf
spheroidal galaxy Leo II, based on JHKs observations obtained with the
near-infrared array WFCAM at the UKIRT telescope. Combining the new
data with optical data, we derived photometric estimates of the
distribution of global metallicity [M/H] of individual red giant stars
from their V-Ks colours. Our results are consistent with the
metallicities of red giant branch (RGB) stars obtained from CaII
triplet spectroscopy, once the age effects are considered.
Description:
Observations of Leo II were carried out in 2005 April 19-20 using
the wide-field NIR camera WFCAM at the UKIRT telescope on Mauna Kea,
Hawaii.
