Two recent short term dimmings of KIC 8462852 (Boyajian's Star) exhibit clear reddening in the B, r' and i' photometric passbands. We show that the intensity ratios of the three pass bands agree well with cooling of an approximately 6800 K black body by about 30K. This agreement, together with other recent findings on the timing and longer term dimmings of this star, support our previous argument that the star's photometric behavior is caused by internal storage of impeded convective flux… 

The First Post-Kepler Brightness Dips of KIC 8462852

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

An Explanation of the Missing Flux from Boyajian's Mysterious Star

A previously unremarkable star in the constellation Cygnus has, in the past year, become known as the most mysterious object in our Galaxy. Boyajian’s star exhibits puzzling episodes of sporadic,

FAMILIES OF PLAUSIBLE SOLUTIONS TO THE PUZZLE OF BOYAJIAN’S STAR

Good explanations for the unusual light curve of Boyajian's Star have been hard to find. Recent results by Montet & Simon lend strength and plausibility to the conclusion of Schaefer that in addition

Extinction and the Dimming of KIC 8462852

To test alternative hypotheses for the behavior of KIC 8462852, we obtained measurements of the star over a wide wavelength range from the UV to the mid-infrared from 2015 October through 2016

Avalanche Statistics Identify Intrinsic Stellar Processes near Criticality in KIC 8462852.

A statistical analysis of the more numerous smaller dimming events by using methods found useful for avalanches in ferromagnetism and plastic flow, which suggests that this star KIC8462852 (Tabby's star) may be near a nonequilibrium critical point.

KIC 8462852 Faded at an Average Rate of 0.164 ± 0.013 Magnitudes per Century from 1890 to 1989

KIC 8462852 is a completely ordinary F3 main-sequence star, except that the light curve from Kepler shows episodes of unique and inexplicable day-long dips with up to 20% dimming. Here, I provide a

Dynamo Action and Magnetic Cycles in F-type Stars

Magnetic activity and differential rotation are commonly observed features on main-sequence F-type stars. We seek to make contact with such observations and to provide a self-consistent picture of

Magnetic Flux Emergence and Decay Rates for Preceder and Follower Sunspots Observed with HMI

We quantify the emergence and decay rates of preceder (p) and follower (f) sunspots within 10 active regions from 2010 to 2014 using Space-weather Helioseismic Magnetic Imager Active Region Patch

A thermal model of sunspot influence on solar luminosity

Recent measurements of the solar irradiance have confirmed that sunspots block energy flow to the photosphere in rough proportion to their area and photometric contrast. We have constructed a

THE STACKED LYα EMISSION PROFILE FROM THE CIRCUM-GALACTIC MEDIUM OF z ∼ 2 QUASARS

In the context of the FLASHLIGHT survey, we obtained deep narrowband images of 15 z ∼ 2 quasars with the Gemini Multi-object Spectrograph on Gemini South in an effort to measure Lyα emission from
