Abstract:
Using data from the Hungarian-made Automated Telescope Network
(HATNet) survey for transiting exoplanets, we measure photometric
rotation periods for 368 Pleiades stars with 0.4~<M~<1.3M☉. We
detect periodic variability for 74 per cent of the cluster members in
this mass range that are within our field-of-view, and 93 per cent of
the members with 0.7~<M~<1.0M☉. This increases, by a factor of
5, the number of Pleiades members with measured periods. We compare
these data to the rich sample of spectroscopically determined
projected equatorial rotation velocities (vsini) available in the
literature for this cluster. Included in our sample are 14 newly
identified probable cluster members which have proper motions,
photometry and rotation periods consistent with membership.
Description:
Photometric time-series observations of the Pleiades cluster were
obtained between 2008 September 15 and 2009 March 16 using the
identical HAT-9 and HAT-10 11-cm aperture robotic telescopes located
at Mauna Kea Observatory (MKO) in Hawaii and at Fred L. Whipple
Observatory (FLWO) in Arizona, respectively.
This catalogue contains photometric rotation periods for stars in the
Pleiades open cluster. Most of the periods were measured from light
curves obtained with the Hungarian-made Automated Telescope Network
(HATNet) of small aperture robotic telescopes located in Arizona and
Hawaii. A handful of stars with periods from the literature that were
not recovered with the HATNet data are also included in the catalogue.

Note on OtherID:
These designations are taken from Stauffer et al., 2007, Cat. J/ApJS/172/663.
Rows without an entry for this column are new candidate cluster members.
Note on Per:
The given period is derived from the HATNet light curves except for
cases where e_Per, fwidth, or rAmp are NULL. In those cases no HATNet
period is available, and the given period is taken from the first
reference listed.
Note on Mass and Radius:
This is derived from the K magnitude and the YY2 isochrones, except for
the 9 stars with periods taken from Scholz & Eisloeffel
(2004A&A...421..259S 2004A&A...421..259S) for which the Baraffe 1998 (Cat. J/A+A/337/403)
isochrones are used.
Note on Bin:
If this is not null the star is a known binary. The entry consists of
two strings separated by a comma. The first string is either VB for a
visual binary, or SB2 for a double-lined spectroscopic binary. The
second string gives the reference for this determination.
