A Search for Analogs of KIC 8462852 (Boyajian's Star): A Second List of Candidates

Edward G. Schmidt

Abstract

In data from the Kepler mission, the normal F3V star KIC 8462852 (Boyajian's star) was observed to exhibit infrequent dips in brightness that have not been satisfactorily explained. A previous paper reported the first results of a search for other similar stars in a limited region of the sky around the Kepler field. This paper expands on that search to cover the entire sky between declinations of +22 degrees and +68 degrees. Fifteen new candidates with low rates of dipping, referred to as "slow dippers" in Paper I, have been identified. The dippers occupy a limited region of the HR diagram and an apparent clustering in space is found. This latter feature suggests that these stars are attractive targets for SETI searches.
