Abstract:
Variability-induced motion (VIM) is an observable effect in
simultaneous astrometric and photometric measurements caused by
brightness variation in one of the components of a double source or
blended image, which manifests itself as a strongly correlated shift
of the optical photocenter. We have processed the entire collection of
Kepler long-cadence light curve data, looking for correlated signals
in astrometry and photometry on the time basis of a quarter-year.
Limiting the VIM correlation coefficient to 0.3, VIM events are
detected for 129525 Kepler stars in at least one quarter. Of 7305
Kepler objects of interest, 4440 are detected as VIM at least once.
Known variable stars and resolved double stars have elevated rates of
VIM detection. Confident VIM occurrences are found for stars with
suggested superflare events, indicating possible signal contamination.
We present a complete catalog of all quarterly VIM detections. This
catalog should be checked for such astrophysically significant events
as transits of exoplanets, new eclipsing stars, and superflares of
solar-type stars.
Description:
The algorithm described in section 4 was applied to the entire
collection of "long-cadence" files archived in the MAST for the
principal Kepler mission. A single variability-induced motion (VIM)
detection corresponds to a complete data set for a given target
collected during one quarter. Therefore, a single target can generate
up to 17 VIM detections in the catalog.
