Abstract:
We have analyzed 1455 fundamental mode RR Lyr stars of the Galactic
field, using the All Sky Automated Survey (ASAS) data. The sample
covers 75% of the sky and contains objects in the close neighborhood
of the Sun, within 4kpc distance. Unlike in the previous analysis of
the close field RRab stars, we see a clear manifestation of the
Oosterhoff groups on the period-amplitude diagram. The relation for
Oosterhoff I type variables becomes strongly flattened at large V
amplitudes, which was not observed for globular cluster RR Lyr.
Description:
The V-band light curves of all 1455 RRab stars in ACVS were extracted
from the catalog and only points with quality flags 'A' and
'B' were retained.
