Variable Star Census in CoRoT "Eyes"

Benkö J. M., Csubry Z.

Acta Astronomica

2007

Vol. 57, No. 1

73--85

A complete catalog of variable stars in the possible observing areas ("eyes") of the CoRoT satellite is presented. All known data sources were cross-correlated and compiled confirming the variability of 81 stars formerly known as suspected variables. By means of the TiFrAn program package a comprehensive variability search was carried out on the NSVS (ROTSE-I) database for the first time in these regions. This search has demonstrated the effectiveness of TiFrAn as a tool for finding and analyzing variable stars in big databases. Our catalog contains 4925 variable stars of which 1396 stars are new discoveries. Also appended is a list of 198 suspected variable stars.

Identification and Astrometry of Variable Stars in M3

221--248

The space distribution of orbital poles for 252 visual binaries is analyzed to check a possible tendency towards parallelism. It is confirmed that orbital planes do not show any trend to be parallel to the Galactic plane. No strong evidence is found for a preferential orientation of the orbital planes for subgroups of binaries with similar periods and eccentricities. Asymmetry in the distribution of orbital poles is seen only for a subgroup of 19 binaries lying closer than 10 pc. Small differences in the distribution of orbital poles are also detected for subgroups with different location on HR diagram.
