Remarks

25 Nov 2013: The 0.85 ± 0.15 Earth radius given by van Verkhoven et al. (2013) depends on the trailing dust cloud.
Rappaport et al. 2012 give a maximum mass of 3 Jupiter mass. Schlawin et al. 2016 estimate a 0.02 Earth mass from the mass loss rate.
29 Aug 2012: The planet could be acompanied by a dust tail (Rappaoprt et al. 2012, Budaj 2013, Brogi et al. 2012)
