7.6 Short time scale variables

Author(s): Maroussia Rolens, Laurent Eyer

The Gaia DR2 provides a first list of suspected periodic short-timescale candidates with periods below 0.5–1 day from about 22 months of Gaia photometry. This section describes the methods and algorithms used for obtaining this list, as well as the verification and validation performed on the obtained sample. All the details on the short timescale analysis methods and results are extensively described in Roelens et al. (2018).
