12CO Rovibrational Spectroscopy of AB Aurigae—A Potential Point Source Is Present

open access: yesThe Astronomical Journal
The Herbig Ae star AB Aurigae hosts a vast, low-inclination protoplanetary disk that exhibits a plethora of substructures, including the protoplanet candidate AB Aur b. We present M -band spectroscopic data taken with the NASA Infrared Telescope Facility

Chondrule Formation in Bow Shocks around Eccentric Planetary Embryos

open access: yes, 2012
Recent isotopic studies of Martian meteorites by Dauphas & Pourmond (2011) have established that large (~ 3000 km radius) planetary embryos existed in the solar nebula at the same time that chondrules - millimeter-sized igneous inclusions found in ...

The Growth & Migration of Jovian Planets in Evolving Protostellar Disks with Dead Zones

open access: yes, 2008
The growth of Jovian mass planets during migration in their protoplanetary disks is one of the most important problems that needs to be solved in light of observations of the exosolar planets.

Evidence for Variable Accretion onto PDS 70 c and Implications for Protoplanet Detections

open access: yesThe Astrophysical Journal Letters
Understanding the processes of planet formation and accretion in young systems is essential to unraveling the initial conditions of planetary systems.

A Protoplanet Candidate in the PDS 66 Disk Indicated by Silicon Sulfide Isotopologues

open access: yesThe Astrophysical Journal Letters
Despite observational progress in planet formation, the stage in which planetesimals grow into planets remains poorly understood. During this phase, protoplanets may develop gaseous envelopes that are warmer than the surrounding disk gas, potentially ...

Detailed structure of the outer disk around HD 169142 with polarized light in H-band

open access: yes, 2015
Coronagraphic imagery of the circumstellar disk around HD 169142 in H-band polarized intensity (PI) with Subaru/HiCIAO is presented. The emission scattered by dust particles at the disk surface in 0.2"

How planetary growth outperforms migration

open access: yes, 2019
Planetary migration is a major challenge for planet formation theories. The speed of Type I migration is proportional to the mass of a protoplanet, while the final decade of growth of a pebble-accreting planetary core takes place at a rate that scales ...
