The All Sky Automated Survey. The Catalog of Variable Stars. II.6h-12h Quarter of the Southern Hemisphere

TL;DR

This paper presents a catalog of over 11,000 variable stars from the southern hemisphere based on extensive photometric data from the ASAS survey, including classifications and infrared flux considerations.

Contribution

It provides a large, classified catalog of variable stars with automated classification methods incorporating infrared data, expanding the scope of previous surveys.

Findings

Over 11,000 variable stars identified and classified.

Automated classification algorithm now includes IRAS infrared fluxes.

Photometric data and light curves are publicly available online.

Abstract

This paper describes the second part of the photometric data from the 9x9 deg ASAS camera monitoring the whole southern hemisphere in the V-band. Preliminary list of variable stars based on observations obtained since January 2001 is presented. Over 2,800,000 stars brighter than V=15 mag on 18,000 frames were analyzed and 11357 were found to be variable (2685 eclipsing, 907 regularly pulsating, 521 Mira and 7244 other, mostly SR, IRR and LPV stars). Periodic light curves have been classified using the automated algorithm, which now takes into account IRAS infrared fluxes. Basic photometric properties are presented in the tables and some examples of thumbnail light curves are printed for reference. All photometric data are available over the INTERNET at http://www.astrouw.edu.pl/~gp/asas/asas.html or http://archive.princeton.edu/~asas
