Bright Opportunities for Atmospheric Characterization of Small Planets: Masses and Radii of K2-3 b, c, d and GJ3470 b from Radial Velocity Measurements and Spitzer Transits
Molly R. Kosiarek, Ian J. M. Crossfield, Kevin K. Hardegree-Ullman +36
We report improved masses, radii, and densities for four planets in two bright M-dwarf systems, K2-3 and GJ3470, derived from a combination of new radial velocity and transit obser…
Spitzer Observations of Interstellar Object 1I/`Oumuamua
DE Trilling, M Mommert, JL Hora +20
1I/`Oumuamua is the first confirmed interstellar body in our Solar System. Here we report on observations of `Oumuamua made with the Spitzer Space Telescope on 2017 November 21--22…
Revisiting the HIP41378 system with K2 and Spitzer
David Berardo, Ian J. M. Crossfield, Michael Werner +12
We present new observations of the multi-planet system HIP~41378, a bright star ( = 8.9, = 7.7) with five known transiting planets. Observations in Campaign 5 of the K2 mi…
Dynamics and Formation of the Near-Resonant K2-24 System: Insights from Transit-Timing Variations and Radial Velocities
Erik A. Petigura, Björn Benneke, Konstantin Batygin +8
While planets between the size of Uranus and Saturn are absent within the Solar System, the star K2-24 hosts two such planets, K2-24b and c, with radii equal to and $7.5~…
Characterizing K2 Candidate Planetary Systems Orbiting Low-Mass Stars III: A High Mass & Low Envelope Fraction for the Warm Neptune K2-55b
Courtney D. Dressing, Evan Sinukoff, Benjamin J. Fulton +23
K2-55b is a Neptune-sized planet orbiting a K7 dwarf with a radius of , a mass of , and an effective temperature of $4300^{+1…
Temperate super-Earths/mini-Neptunes around M/K dwarfs Consist of 2 Populations Distinguished by Their Atmospheres
Xueying Guo, Sarah Ballard, Diana Dragomir +2
Studies of the atmospheres of hot Jupiters reveal a diversity of atmospheric composition and haze properties. Similar studies on individual smaller, temperate planets are rare due…
An Improved Transit Measurement for a 2.4 R_{Earth} Planet Orbiting A Bright Mid-M Dwarf K228
Ge Chen, Heather A. Knutson, Courtney D. Dressing +13
We present a new {\em Spitzer} transit observation of K228b, a sub-Neptune () orbiting a relatively bright (, $K_{\rm mag…
