Abundance, Sizes, and Major Element Compositions of Components in CR and LL Chondrites: Formation from Single Reservoirs

Denton S. Ebel, Marina E. Gemma, Samuel P. Alpert +3

Abundances, apparent sizes, and individual chemical compositions of chondrules, refractory inclusions, other objects and surrounding matrix have been determined for Semarkona (LL3.…

Patchy Forsterite Clouds in the Atmospheres of Two Highly Variable Exoplanet Analogs

Johanna M. Vos, Ben Burningham, Jacqueline K. Faherty +12

We present an atmospheric retrieval analysis of a pair of highly variable, Myr old, early-T type planetary-mass exoplanet analogs SIMP J01365662+0933473 and 2MASS J213926…

Let the Great World Spin: Revealing the Stormy, Turbulent Nature of Young Giant Exoplanet Analogs with the Spitzer Space Telescope

Johanna M. Vos, Jacqueline K. Faherty, Jonathan Gagné +5

We present a survey for photometric variability in young, low-mass brown dwarfs with the Spitzer Space Telescope. The 23 objects in our sample show robust signatures of youth and s…

Precise Masses and Orbits for Nine Radial Velocity Exoplanets

Yiting Li, Timothy D. Brandt, G. Mirek Brandt +6

Radial velocity (RV) surveys have discovered hundreds of exoplanetary systems but suffer from a fundamental degeneracy between planet mass and orbital inclination . In thi…

Longitudinally Resolved Spectral Retrieval (ReSpect) of WASP-43b

Patricio E. Cubillos, Dylan Keating, Nicolas B. Cowan +6

Thermal phase variations of short period planets indicate that they are not spherical cows: day-to-night temperature contrasts range from hundreds to thousands of degrees, rivaling…

The Influence of Age on the Relative Frequency of Super-Earths and Sub-Neptunes

Angeli Sandoval, Gabriella Contardo, Trevor J. David

There is growing evidence that the population of close-in planets discovered by the Kepler mission was sculpted by atmospheric loss, though the typical timescale for this evolution…

Evolution of the Exoplanet Size Distribution: Forming Large Super-Earths Over Billions of Years

Trevor J. David, Gabriella Contardo, Angeli Sandoval +9

The radius valley, a bifurcation in the size distribution of small, close-in exoplanets, is hypothesized to be a signature of planetary atmospheric loss. Such an evolutionary pheno…

An ALMA Disk Mass for the Candidate Protoplanetary Companion to FW Tau

Adam L. Kraus, Sean M. Andrews, Brendan P. Bowler +5

We present ALMA observations of the FW Tau system, a close binary pair of M5 stars with a wide-orbit (300 AU projected separation) substellar companion. The companion is extremely…
