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…
New constraints on quantum foam models from X-ray and gamma-ray observations of distant quasars
Eric S. Perlman, Saul A. Rappaport, Y. Jack Ng +3
Astronomical observations of distant quasars may be important to test models for quantum gravity, which posit Planck-scale spatial uncertainties ('spacetime foam') that would produ…
On the Detection of Non-Transiting Exoplanets with Dusty Tails
John DeVore, Saul Rappaport, Roberto Sanchis-Ojeda +2
We present a way of searching for non-transiting exoplanets with dusty tails. In the transiting case, the extinction by dust during the transit removes more light from the beam tha…
New Constraints on Quantum Gravity from X-ray and Gamma-Ray Observations
Eric S. Perlman, Saul A. Rappaport, Wayne A. Christensen +3
One aspect of the quantum nature of spacetime is its "foaminess" at very small scales. Many models for spacetime foam are defined by the accumulation power , which parameterizes…
Multiwavelength Observations of the Candidate Disintegrating sub-Mercury KIC 12557548b
Bryce Croll, Saul Rappaport, John DeVore +11
We present multiwavelength photometry, high angular resolution imaging, and radial velocities, of the unique and confounding disintegrating low-mass planet candidate KIC 12557548b.…
