The Astrophysical Journal, 2023 Thanks to “dust-to-planet” simulations (DTPSs), which treat the collisional evolution directly from dust to giant-planet cores in a protoplanetary disk, we showed that giant-planet cores are formed in ≲10 au in several 10 ^5 yr, because porous pebbles ...

The Evolution of Protoplanetary Disk Edges [PDF]
The Astrophysical Journal, 2004 We investigate gap formation in gaseous protostellar disks by a planet in a circular orbit in the limit of low disk viscosity. This regime may be appropriate to an aging disk after the epoch of planet formation. We find that the distance of planet to the gap outer boundary can be between the location of the $m=2$ and $m=1$ outer Lindblad resonances ...

High-resolution Millimeter Imaging of the CI Tau Protoplanetary Disk: A Massive Ensemble of Protoplanets from 0.1 to 100 au [PDF]
Astrophysical Journal, 2018 We present high-resolution millimeter continuum imaging of the disk surrounding the young star CI Tau, a system hosting the first hot Jupiter candidate in a protoplanetary disk system.

Interferometry and the study of protoplanetary disks [PDF]
EPJ Web of Conferences, 2015 Interferometry offers access to scales that are unresolvable using single dish telescopes, which is especially important when investigating objects with small angular sizes, such as protoplanetary disks. This Chapter introduces the concept of interferometry, and describes the basic aspects of interferometric observations when considering long (i.e. sub-

ALMA Observations of Polarization from Dust Scattering in the IM Lup Protoplanetary Disk [PDF]
Astrophysical Journal, 2018 We present 870 μm ALMA observations of polarized dust emission toward the Class II protoplanetary disk IM Lup. We find that the orientation of the polarized emission is along the minor axis of the disk, and that the value of the polarization fraction ...

Kinematic Evidence of an Embedded Protoplanet in HD 142666 Identified by Machine Learning
The Astrophysical Journal, 2023 Observations of protoplanetary disks have shown that forming exoplanets leave characteristic imprints on the gas and dust of the disk. In the gas, these forming exoplanets cause deviations from Keplerian motion, which can be detected through molecular ...

First Detection of the Simplest Organic Acid in a Protoplanetary Disk [PDF]
Astrophysical Journal, 2018 The formation of asteroids, comets, and planets occurs in the interior of protoplanetary disks during the early phase of star formation. Consequently, the chemical composition of the disk might shape the properties of the emerging planetary system.

Odessa Astronomical Publications, 2017 The mechanism of protoplanetary system formation as a result of a merge of binary star consisting of the low mass (0.5-1M⊙) pre-MS stars is considered. During the merging the more massive component is destroyed. The substance of the destroyed component

RINGED SUBSTRUCTURE AND A GAP AT 1 au IN THE NEAREST PROTOPLANETARY DISK [PDF]
, 2016 We present long baseline Atacama Large Millimeter/submillimeter Array (ALMA) observations of the 870 μm continuum emission from the nearest gas-rich protoplanetary disk, around TW Hya, that trace millimeter-sized particles down to spatial scales as small
