New periodic variables from the Hipparcos epoch photometry
@article{Koen2001NewPV, title={New periodic variables from the Hipparcos epoch photometry}, author={Chris Koen and Laurent Eyer}, journal={Monthly Notices of the Royal Astronomical Society}, year={2001}, volume={331}, pages={45-59} }
Two selection statistics are used to extract new candidate periodic variables from the epoch photometry of the Hipparcos catalogue. The primary selection criterion is a signal-to-noise ratio. The dependence of this statistic on the number of observations is calibrated using about 30 000 randomly permuted Hipparcos data sets. A significance level of 0.1 per cent is used to extract a first batch of candidate variables. The second criterion requires that the optimal frequency be unaffected if the…

Context. Variability is a key factor for understanding the nature of the most massive stars, the OB stars. Such stars lie closest to the unstable upper limit of star formation. Aims. In terms of…
Detectability of micro-variables in the ASAS database: the Scorpius-Centaurus Complex
- Physics
- 2013
Nine years of photometry in the ASAS V-band catalogue is exploited to develop a method to select in an objective way the best quality data and detect low-amplitude variables, and the database contains much more information on photometric variables than retrieved commonly.
