Abstract:
We report results of spectroscopic and photometric observations of ten
delta Sct stars and one eclipsing binary in the open cluster NGC 1817,
and of ten delta Sct stars and two other variables in the open cluster
NGC 7062. For all targets in NGC 1817 and for three targets in NGC 7062
the radial velocity and projected rotational velocity are determined.
For all stars the effective temperature and surface gravity is
measured.
Description:
Stroemgren photometry for NGC 7062 and standard stars were collected
at the 2.5-m Nordic Optical Telescope, La Palma, Spain, on three
nights in August 2004.
Spectroscopic observations were carried out at the Nordic Optical
Telescope by S.F. (13-14 August 2004), and by T.A. and J.M.-Z.
(20-22 November 2004). The Andalucia Faint Object Spectrograph and
Camera, ALFOSC, was used on both observing runs.
