The All Sky Automated Survey. The Catalog of Variable Stars. V. Declinations 0 deg - 28 deg of the Northern Hemisphere

Abstract

This paper contains the fifth part of the Catalog of Variable Stars created from the V-band photometric data collected by 9x9 deg camera of the All Sky Automated Survey. Preliminary list of variable stars found in the fields located between declination 0 and +28 deg of the northern hemisphere is presented. 11,509 stars brighter than V=15 were found to be variable (2,482 eclipsing, 1,397 regularly pulsating, 318 Mira and 7,310 other stars). Automated algorithm taking into account light curve properties (period, fourier coefficients) and other available data (2MASS colors, IRAS fluxes) was applied to roughly classify objects. Basic photometric properties are presented in the tables and thumbnail light curves are made available for reference. All the photometric data are available over the INTERNET at http://www.astrouw.edu.pl/~gp/asas/asas.html or http://archive.princeton.edu/~asas
