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 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 کاملAvalanche Statistics Identify Intrinsic Stellar Processes near Criticality in KIC 8462852.
The star KIC8462852 (Tabby's star) has shown anomalous drops in light flux. We perform a statistical analysis of the more numerous smaller dimming events by using methods found useful for avalanches in ferromagnetism and plastic flow. Scaling exponents for avalanche statistics and temporal profiles of the flux during the dimming events are close to mean field predictions. Scaling collapses sugg...
متن کاملCrowding by a repeating pattern.
Theinability to recognize a peripheral target among flankers is called crowding. For a foveal target, crowding can be distinguished from overlap masking by its sparing of detection, linear scaling with eccentricity, and invariance with target size.Crowding depends on the proximity and similarity of the flankers to the target. Flankers that are far from or dissimilar to the target do not crowd i...
متن کاملVentilator-associated pneumonia with circuit changes every 2 days versus every week.
BACKGROUND Frequent ventilator circuit changes are expensive and sometimes unnecessary. Following the worldwide trend to lengthen the intervals for ventilator circuit change from 2 days to 1 week, this study aims to assure that low rate of ventilator-associated pneumonia (VAP) can be maintained with cost containment. METHODS Ventilator circuits were routinely changed every 7 days in the study...
