Simultaneous, Multi-Wavelength Variability Characterization of the Free-Floating Planetary Mass Object PSO J318.5-22
Beth Biller, Johanna Vos, Esther Buenzli +15
We present simultaneous HST WFC3 + Spitzer IRAC variability monitoring for the highly-variable young (20 Myr) planetary-mass object PSO J318.5-22. Our simultaneous HST + Spit…
Planet Candidates from K2 Campaigns 5-8 and Follow-Up Optical Spectroscopy
Erik A. Petigura, Ian J. M. Crossfield, Howard Isaacson +10
We present 151 planet candidates orbiting 141 stars from K2 campaigns 5-8 (C5-C8), identified through a systematic search of K2 photometry. In addition, we identify 16 targets as l…
Exoplanet phase curves: observations and theory
Vivien Parmentier, Ian Crossfield
Phase curves are the best technique to probe the three dimensional structure of exoplanets' atmospheres. In this chapter we first review current exoplanets phase curve observations…
Light Curve Modulation of Low Mass Stars in K2. I. Identification of 508 Fast Rotators in the Solar Neighborhood
Dicy Ann Saylor, Sebastien Lépine, Ian Crossfield +1
The K2 mission is targeting large numbers of nearby (d<100 pc) GKM dwarfs selected from the SUPERBLINK proper motion survey (mu>40 mas yr^-1, V<20). Additionally, the mission is ta…
The Science Case for an Extended Spitzer Mission
Jennifer C. Yee, Giovanni G. Fazio, Robert Benjamin +45
Although the final observations of the Spitzer Warm Mission are currently scheduled for March 2019, it can continue operations through the end of the decade with no loss of photome…
Trends in Atmospheric Properties of Neptune-Size Exoplanets
Ian J. M. Crossfield, Laura Kreidberg
Precise atmospheric observations have been made for a growing sample of warm Neptunes. Here we investigate the correlations between these observations and a large number of system…
