Kic 8462852 Faded throughout the Kepler Mission
KIC 8462852 is a superficially ordinary main sequence F star for which Kepler detected an unusual series of brief dimming events. We obtain accurate relative photometry of KIC 8462852 from the Kepler full-frame images, finding that the brightness of KIC 8462852 monotonically decreased over the four years it was observed by Kepler. Over the first ∼1000 days KIC 8462852 faded approximately linear...
متن کاملAsteroseismic modelling of the two F-type hybrid pulsators KIC 10080943A and KIC 10080943B
Context. Pulsating binary stars are ideal targets for testing the theory of stellar structure and evolution. Fundamental parameters can be derived to high precision from binary modelling and provide crucial constraints for seismic modelling. High-order gravity modes are sensitive to the conditions near the convective core and therefore allow for a determination of parameters describing interior...
متن کاملKIC 2856960: the impossible triple star
KIC 2856960 is a star in the Kepler field which was observed by Kepler for 4 years. It shows the primary and secondary eclipses of a close binary of period 0.258 d as well as complex dipping events that last for about 1.5 d at a time and recur on a 204 d period. The dips are thought to result when the close binary passes across the face of a third star. In this paper we present an attempt to mo...
متن کاملOptical Polarimetry of KIC 8462852 in May–August 2017
We present optical polarimetry in the period May–August 2017 of the enigmatic “dipping”star KIC 8462852. During that period three ∼ 1% photometric dips were reported by other observers. We measured the average absolute polarization of the source, and find no excess or unusual polarization compared to a nearby comparison star. We place tight upper limits on any change in the degree of polarizati...
متن کاملThe Relation between the Transit Depths of Kic 12557548b & the Stellar Rotation Period
Kawahara and collaborators analyzed the transits of the candidate disintegrating Mercury-mass planet KIC 12557548b and suggested that the transit depths were correlated with the phase of the stellar rotation. We have carried out a more extensive and comprehensive analysis of the transit depths of KIC 12557548b and confirm that there is indeed a robust, statistically significant signal in the tr...
