A dearth of small particles in the transiting material around the white dwarf WD 1145+017
S. Xu, S. Rappaport, R. van Lieshout +35
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 e…
Periodic optical variability and debris accretion in white dwarfs: a test for a causal connection
Na'ama Hallakoun, Dan Maoz, Eric Agol +9
Recent Kepler photometry has revealed that about half of white dwarfs (WDs) have periodic, low-level (~ 1e-4 - 1e-3), optical variations. Hubble Space Telescope (HST) ultraviolet s…
MOA-2016-BLG-227Lb: A Massive Planet Characterized by Combining Lightcurve Analysis and Keck AO Imaging
Naoki Koshimoto, Yossi Shvartzvald, David Bennett +55
We report the discovery of a microlensing planet --- MOA-2016-BLG-227Lb --- with a large planet/host mass ratio of . This event was located near the …
Once in a blue moon: detection of 'bluing' during debris transits in the white dwarf WD1145+017
N. Hallakoun, S. Xu, D. Maoz +16
The first transiting planetesimal orbiting a white dwarf was recently detected in K2 data of WD1145+017 and has been followed up intensively. The multiple, long, and variable trans…
