Asteroid Photometry from the Transiting Exoplanet Survey Satellite: A Pilot Study

A. McNeill, M. Mommert, D. E. Trilling +2

The {\it Transiting Exoplanet Survey Satellite} (TESS) searches for planets transiting bright and nearby stars using high-cadence, large-scale photometric observations. Full Frame…

Magnetic field strengths of hot Jupiters from signals of star-planet interactions

P. Wilson Cauley, Evgenya L. Shkolnik, Joe Llama +1

Evidence of star-planet interactions in the form of planet-modulated chromospheric emission has been noted for a number of hot Jupiters. Magnetic star-planet interactions involve t…

CO Detected in CI Tau b: Hot Start Implied by Planet Mass and M

Laura Flagg, Christopher M. Johns-Krull, Larissa Nofi +5

We acquired high resolution IR spectra of CI Tau, the host star of one of the few young planet candidates amenable to direct spectroscopic detection. We confirm the planet's existe…

A New Two-Molecule Combination Band as Diagnostic of Carbon Monoxide Diluted in Nitrogen Ice On Triton

S. C. Tegler, T. D. Stufflebeam, W. M. Grundy +11

A combination band due to a mechanism whereby a photon excites two or more vibrational modes ({\it e.g.} a bend and a stretch) of an individual molecule is commonly seen in laborat…

Constraining Stellar Photospheres as an Essential Step for Transmission Spectroscopy of Small Exoplanets

Benjamin V. Rackham, Arazi Pinhas, Dániel Apai +29

Transmission spectra probe the atmospheres of transiting exoplanets, but these observations are also subject to signals introduced by magnetic active regions on host stars. Here we…

MOVES II. Tuning in to the radio environment of HD189733b

R. D. Kavanagh, A. A. Vidotto, D. Ó Fionnagáin +7

We present stellar wind modelling of the hot Jupiter host HD189733, and predict radio emission from the stellar wind and the planet, the latter arising from the interaction of the…
