A dearth of small particles in the transiting material around the white dwarf WD 1145+017 Open
White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves through deep, broad, and evolving transits in the star's light curve. Here, we report…

Multiwavelength Transit Observations of the Candidate Disintegrating Planetesimals Orbiting WD 1145+017 Open
We present multiwavelength, ground-based follow-up photometry of the white dwarf WD 1145+017, which has recently been suggested to be orbited by up to six or more short-period, low-mass, disintegrating planetesimals. We detect nine signifi…

KEPLER TRANSIT DEPTHS CONTAMINATED BY A PHANTOM STAR Open
We present ground-based observations from the Discovery Channel Telescope (DCT) of three transits of Kepler-445c—a supposed super-Earth exoplanet with properties resembling GJ 1214b—and demonstrate that the transit depth is ∼50% shallower …

Long-term, Multiwavelength Light Curves of Ultra-Cool Dwarfs: II. The evolving Light Curves of the T2.5 SIMP 0136 & the Uncorrelated Light Curves of the M9 TVLM 513 Open
We present 17 nights of ground-based, near-infrared photometry of the variable L/T transition brown dwarf SIMP J013656.5+093347 and an additional 3 nights of ground-based photometry of the radio-active late M-dwarf TVLM 513-46546. Our TVLM…

Drifting asteroid fragments around WD 1145+017 Open
We have obtained extensive photometric observations of the polluted white dwarf WD 1145+017 which has been reported to be transited by at least one, and perhaps several, large asteroids with dust emission. Observation sessions on 37 nights…

NEAR-INFRARED THERMAL EMISSION DETECTIONS OF A NUMBER OF HOT JUPITERS AND THE SYSTEMATICS OF GROUND-BASED NEAR-INFRARED PHOTOMETRY Open
We present detections of the near-infrared thermal emission of three hot Jupiters and one brown dwarf using the Wide-field Infrared Camera (WIRCam) on the Canada-France-Hawaii Telescope (CFHT). These include Ks-band secondary eclipse detec…

The relation between the transit depths of KIC 12557548b and the stellar rotation period Open
Kawahara and collaborators analyzed the transits of the candidate\ndisintegrating Mercury-mass planet KIC 12557548b and suggested that the transit\ndepths were correlated with the phase of the stellar rotation. We analyze the\ntransit dept…

Tracking the stellar longitudes of starspots in short-period Kepler binaries Open
We report on a new method for tracking the phases of the orbital modulations\nin very short-period, near-contact, and contact binary systems systems in order\nto follow starspots. We apply this technique to Kepler light curves for 414\nbin…
