Two-stage disruption of resonant chains
Nick Choksi, Yoram Lithwick, Eugene Chiang +1
TESS is enabling the discovery of transiting planets around young stars. These observations suggest that most close-in planets were born in chains of mean-motion resonances that br…

The Resonant Remains of Broken Chains from Major and Minor Mergers
Rixin Li, Eugene Chiang, Nick Choksi +1
TESS and Kepler have revealed that practically all close-in sub-Neptunes form in mean-motion resonant chains, most of which unravel on timescales of 100 Myr. Using N-body integrati…

Spectral Energy Distributions of Disc-Embedded Accreting Protoplanets
Nick Choksi, Eugene Chiang
Many dozens of circumstellar discs show signatures of sculpting by planets. To help find these protoplanets by direct imaging, we compute their broadband spectral energy distributi…
