Dusty tails of evaporating exoplanets. II. Physical modelling of the KIC 12557548b light curve

Context. Evaporating rocky exoplanets, such as KIC 12557548b, eject large amounts of dust, which can trail the planet in a comet- like tail. When such objects occult their host star, the resulting transit signal contains information about the dust in …

Analysis and interpretation of 15 quarters of Kepler data of the disintegrating planet KIC 12557548 b

Context. The Kepler object KIC 12557548 shows irregular eclipsing behaviour with a constant 15.685 h period, but strongly varying transit depth. The object responsible for this is believed to be a disintegrating planet forming a trailing dust cloud …

Evidence for the disintegration of KIC 12557548 b

Context. The Kepler object KIC 12557548 b is peculiar. It exhibits transit-like features every 15.7 h that vary in depth between 0.2% and 1.2%. Rappaport et al. (2012, ApJ, 752, 1) explain the observations in terms of a disintegrating, rocky planet …
