Ejection of material --"Jurads" -- from post main sequence planetary systems
Brad Hansen, Ben Zuckerman
We show that the rate of pollution of white dwarfs by asteroidal material implies a concomitant rate of material ejection that can contribute significantly to the population of int…
Constraining Planetary Migration and Tidal Dissipation with Coeval Hot Jupiters
Christopher E. O'Connor, Bradley M. S. Hansen
We investigate the constraints on the formation of, and tidal dissipation processes in, hot Jupiters (HJs) that can be inferred based on reliable knowledge of the age of a system o…
Three's Company: An additional non-transiting super-Earth in the bright HD 3167 system, and masses for all three planets
Jessie L. Christiansen, Andrew Vanderburg, Jennifer Burt +55
HD 3167 is a bright (V = 8.9), nearby K0 star observed by the NASA K2 mission (EPIC 220383386), hosting two small, short-period transiting planets. Here we present the results of a…
K2-66b and K2-106b: Two extremely hot sub-Neptune-size planets with high densities
Evan Sinukoff, Andrew W. Howard, Erik A. Petigura +20
We report precise mass and density measurements of two extremely hot sub-Neptune-size planets from the K2 mission using radial velocities, K2 photometry, and adaptive optics imagin…
On the Spin States of Habitable Zone Exoplanets Around M Dwarfs: The Effect of a Near-Resonant Companion
Alec M. Vinson, Brad M. S. Hansen
One longstanding problem for the potential habitability of planets within M dwarf systems is their likelihood to be tidally locked in a synchronously rotating spin state. This prob…
