A Near-Infrared Chemical Inventory of the Atmosphere of 55 Cancri e
Emily K. Deibert, Ernst J. W. de Mooij, Ray Jayawardhana +4
We present high-resolution near-infrared spectra taken during eight transits of 55 Cancri e, a nearby low-density super-Earth with a short orbital period (< 18 hours). While this e…
Decaying Orbit of the Hot Jupiter WASP-12b: Confirmation with TESS Observations
Jake D. Turner, Andrew Ridden-Harper, Ray Jayawardhana
Theory suggests that the orbits of some close-in giant planets should decay due to tidal interactions with their host stars. To date, WASP-12b is the only hot Jupiter reported to h…
TESS Observations of the Hot Jupiter Exoplanet XO-6b: No Evidence of Transit Timing Variations
Andrew R. Ridden-Harper, Jake D. Turner, Ray Jayawardhana
From previous ground-based observations, the hot Jupiter exoplanet XO-6b was reported to exhibit apparently periodic transit timing variations (TTVs), with a semi-amplitude of 14 m…
Search for gas from the disintegrating rocky exoplanet K2-22b
A. R. Ridden-Harper, I. A. G. Snellen, C. U. Keller +1
[Abridged] Aims. We searched for circumplanetary sodium and ionized calcium gas around the disintegrating rocky exoplanet K2-22 b to constrain its gas-loss and sublimation processe…
Spectroscopic Transit Search: a self-calibrating method for detecting planets around bright stars
Lennart van Sluijs, Ernst de Mooij, Matthew Kenworthy +7
We search for transiting exoplanets around the star Pictoris using high resolution spectroscopy and Doppler imaging that removes the need for standard star observations. These…
Chromatic transit light curves of disintegrating rocky planets
A. R. Ridden-Harper, C. U. Keller, M. Min +2
Context. Kepler observations have revealed a class of short period exoplanets, of which Kepler-1520 b is the prototype, which have comet-like dust tails thought to be the result of…
