New Paper: "The first post-Kepler brightness dips of KIC 8462852"

[Abridged abstract:] We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometric surveillance started in October 2015, and a sequence of dipping began in 2017 May continuing on through the end of 2017, when the star was no longer visible from Earth. We distinguish four main 1–2.5% dips, named “Elsie,” “Celeste,” “Skara Brae,”  and “Angkor” , which persist on timescales from several days to weeks. Our main results so far are: (i) there are no apparent changes of the stellar spectrum or polarization during the dips; (ii) the multiband photometry of the dips shows differential reddening favoring non-grey extinction. Click on link below for press release and additional information.

New Paper: "Non-grey dimming events of KIC 8462852 from GTC spectrophotometry"

[Abridged abstract:] We report ground-based spectrophotometry of KIC 8462852, during its first dimming events since the end of the Kepler mission. The dimmings show a clear colour-signature, and are deeper in visual blue wavelengths than in red ones.. Click on link below for press release and additional information.
