Assessing the Impact of High-Resolution Imaging on Statistical Validation of TESS Planet Candidates
Michael Collier, Steven Giacalone, Brian Derfer +38
High-resolution imaging is widely used to constrain false-positive scenarios in exoplanet validation, but it is a finite follow-up resource that reaches only a subset of candidates…

Direct Detection of SDSS J0926+3624 Orbital Expansion with ARCONS
P. Szypryt, G. E. Duggan, B. A. Mazin +10
AM Canum Venaticorum (AM CVn) stars belong to a class of ultra-compact, short period binaries with spectra dominated largely by helium. SDSS J0926+3624 is of particular interest as…
Excess Optical Enhancement Observed with ARCONS for Early Crab Giant Pulses
M. J. Strader, M. D. Johnson, B. A. Mazin +11
We observe an extraordinary link in the Crab pulsar between the enhancement of an optical pulse and the timing of the corresponding giant radio pulse. At optical through infrared w…
Measurement of Spin-Orbit Misalignment and Nodal Precession for the Planet around Pre-Main-Sequence Star PTFO 8-8695 From Gravity Darkening
Jason W. Barnes, Julian C. van Eyken, Brian K. Jackson +2
PTFO 8-8695b represents the first transiting exoplanet candidate orbiting a pre-main-sequence star. We find that the unusual lightcurve shapes of PTFO 8-8695 can be explained by tr…
