Impacting Atmospheres: How Late-Stage Pollution Alters Exoplanet Composition
Emilia Vlahos, Yayaati Chachan, Vincent Savignac +1
Atmospheric composition of exoplanets is often considered as a probe of the planet's formation condition. How exactly the initial chemical memory may be altered from the birth to t…
A Fourth Planet in the Kepler-51 System Revealed by Transit Timing Variations
Kento Masuda, Jessica E. Libby-Roberts, John H. Livingston +49
Kepler-51 is a -old Sun-like star hosting three transiting planets with radii - and orbital periods -$130\,\mathrm{day…
Metastable Helium Reveals an Extended Atmosphere for the Gas Giant HAT-P-18b
Kimberly Paragas, Shreyas Vissapragada, Heather A. Knutson +6
The metastable helium line at 1083 nm can be used to probe the extended upper atmospheres of close-in exoplanets and thus provide insight into their atmospheric mass loss, which is…
Radial Gradients in Dust-to-Gas Ratio Lead to Preferred Region for Giant Planet Formation
Yayaati Chachan, Eve J. Lee, Heather A. Knutson
The Rosseland mean opacity of dust in protoplanetary disks is often calculated assuming the interstellar medium (ISM) size distribution and a constant dust-to-gas ratio. However, t…
A Featureless Infrared Transmission Spectrum for the Super-Puff Planet Kepler-79d
Yayaati Chachan, Daniel Jontof-Hutter, Heather A. Knutson +12
Extremely low density planets ('super-puffs') are a small but intriguing subset of the transiting planet population. With masses in the super-Earth range ( M) and…
PLATON II: New Capabilities And A Comprehensive Retrieval on HD 189733b Transit and Eclipse Data
Michael Zhang, Yayaati Chachan, Eliza M. -R. Kempton +3
Recently, we introduced PLanetary Atmospheric Tool for Observer Noobs (PLATON), a Python package that calculates model transmission spectra for exoplanets and retrieves atmospheric…
