A Uniform Analysis of Debris Disks with the Gemini Planet Imager I: An Empirical Search for Perturbations from Planetary Companions in Polarized Light Images

Katie A. Crotts, Brenda C. Matthews, Gaspard Duchêne +37

The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-infrared. The GPI Exoplanet Survey (GPIES) imaged twenty-four debris disks in polarized -band lig…

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…

WASP-107b's density is even lower: a case study for the physics of planetary gas envelope accretion and orbital migration

Caroline Piaulet, Björn Benneke, Ryan A. Rubenzahl +21

With a mass in the Neptune regime and a radius of Jupiter, WASP-107b presents a challenge to planet formation theories. Meanwhile, the planet's low surface gravity and the star's b…

Can Large-Scale Migration Explain the Giant Planet Occurrence Rate?

Tim Hallatt, Eve J Lee

The giant planet occurrence rate rises with orbital period out to at least 300 days. Large-scale planetary migration through the disk has long been suspected to be the physic…

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…

Primordial Radius Gap and Potentially Broad Core Mass Distributions of Super-Earths and Sub-Neptunes

Eve J. Lee, Nicholas J. Connors

The observed radii distribution of {\it Kepler} exoplanets reveals two distinct populations: those that are more likely to be terrestrials () and those that ar…
