Abstract:
A search for RR Lyrae stars has been conducted in the publicly
available data of the Northern Sky Variability Survey. Candidates have
been selected by the statistical properties of their variation; the
standard deviation, skewness and kurtosis with appropriate limits
determined from a sample 314 known RRab and RRc stars listed in the
General Catalogue of Variable Stars. From the period analysis and
light-curve shape of over 3000 candidates 785 RR Lyrae have been
identified of which 188 are previously unknown. The light curves were
examined for the Blazhko effect and several new stars showing this
were found. Six double-mode RR Lyrae stars were also found of which
two are new discoveries. Some previously known variables have been
reclassified as RR Lyrae stars and similarly some RR Lyrae stars have
been found to be other types of variable, or not variable at all.
Description:
Position, type and period for RR Lyrae variables found in the Northern
Sky Variability Survey (Wozniak+, 2004AJ....127.2436W 2004AJ....127.2436W).
