Abstract:
We present statistical characteristics of 1578 δ Scuti stars
including nearby field stars and cluster member stars within the Milky
Way. We obtained 46% of these stars (718 stars) from work by Rodriguez
and collected the remaining 54% of stars (860 stars) from other
literature. We updated the entries with the latest information of sky
coordinates, color, rotational velocity, spectral type, period,
amplitude, and binarity. The majority of our sample is well
characterized in terms of typical period range (0.02-0.25days),
pulsation amplitudes (<0.5mag), and spectral types (A-F type). Given
this list of δ Scuti stars, we examined relations between their
physical properties (i.e., periods, amplitudes, spectral types, and
rotational velocities) for field stars and cluster members, and
confirmed that the correlations of properties are not significantly
different from those reported in Rodriguez's work. All the δ
Scuti stars are cross-matched with several X-ray and UV catalogs,
resulting in 27 X-ray and 41 UV-only counterparts. These counterparts
are interesting targets for further study because of their uniqueness
in showing δ Scuti-type variability and X-ray/UV emission at the
same time. The compiled catalog can be accessed through the Web
interface http://stardb.yonsei.ac.kr/DeltaScuti.
Description:
We compiled a new catalog of 1578 δ Scuti stars (Table3)
including the catalogs compiled by Rodriguez et al. (2000, cat.
J/A+AS/144/469), Rodriguez & Lopez-Gonzalez (2000, cat.
J/A+A/359/597), Hipparcos (cat I/239), OGLE (Optical Gravitational
Lensing Experiment; 1997, cat. II/213), MACHO (MAssive Compact Halo
Object.; 2000ApJ...536..798A 2000ApJ...536..798A), ROTSE (2003, cat. J/A+A/404/621), ASAS
(All-Sky Automated Survey.; cat. II/264), TAOS (Taiwan-American
Occultation Survey; 2010AJ....139..757K 2010AJ....139..757K), GCVS (General Catalog of
Variable Stars; cat. B/gcvs). Our new catalog is accessible online at
http://stardb.yonsei.ac.kr/DeltaScuti.
