Abstract:
V-band time-series CCD photometric observations of the
intermediate-age open cluster M11 were performed to search for
variable stars.
Description:
We carried out time-series observations of M11 on 18 nights in 2004
June using a CCD camera attached to the LOAO 1.0m telescope in
Arizona.
A total of 1001 time-series images, i.e., 406 images with a long
exposure of 600s and 595 images with a short exposure of 60s, were
obtained with a V-band filter to secure faint objects, as well as
bright ones. For the purpose of constructing a BV color-magnitude
diagram of M11, additional B-band observations were made on one night
of 2004 October: two frames with exposure times of 1000 and 100s.
