Abstract
High resolution spectra of a magnified bulge star
were obtained at the 8 m Kueyen VLT-UT2 telescope with
the UVES spectrograph.
The source is a bulge giant of baseline magnitude
,
magnified to
. These data allow us to derive the
stellar parameters
of effective temperature
K,
gravity log
, reddening
,
metallicity and and [O/Fe]
0.0
for EROS-BLG-2000-5.
The giant appears to be located in the
far side of the bulge.
Key words: Galaxy: bulge -- abundances -- gravitational lensing
