Observations of protoplanetary disk structures

SM Andrews - Annual Review of Astronomy and Astrophysics, 2020 - annualreviews.org
The disks that orbit young stars are the essential conduits and reservoirs of material for star
and planet formation. Their structures, meaning the spatial variations of the disk physical …

A kinematical detection of two embedded Jupiter-mass planets in HD 163296

R Teague, J Bae, EA Bergin, T Birnstiel… - The Astrophysical …, 2018 - iopscience.iop.org
We present the first kinematical detection of embedded protoplanets within a protoplanetary
disk. Using archival Atacama Large Millimetre Array (ALMA) observations of HD 163296, we …

Molecules with ALMA at Planet-forming Scales (MAPS). XVIII. Kinematic Substructures in the Disks of HD 163296 and MWC 480

R Teague, J Bae, Y Aikawa, SM Andrews… - The Astrophysical …, 2021 - iopscience.iop.org
We explore the dynamical structure of the protoplanetary disks surrounding HD 163296 and
MWC 480 as part of the Molecules with ALMA at Planet-forming Scales (MAPS) large …

Radial migration of gap-opening planets in protoplanetary disks. I. The case of a single planet

KD Kanagawa, H Tanaka… - The Astrophysical …, 2018 - iopscience.iop.org
A large planet orbiting a star in a protoplanetary disk opens a density gap along its orbit due
to the strong disk–planet interaction and migrates with the gap in the disk. It is expected that …

Planet formation: key mechanisms and global models

SN Raymond, A Morbidelli - … of Exoplanetary Systems: Lecture Notes of …, 2022 - Springer
Abstract Models of planet formation are built on underlying physical processes. In order to
make sense of the origin of the planets we must first understand the origin of their building …

A remnant planetary core in the hot-Neptune desert

DJ Armstrong, TA Lopez, V Adibekyan, RA Booth… - Nature, 2020 - nature.com
The interiors of giant planets remain poorly understood. Even for the planets in the Solar
System, difficulties in observation lead to large uncertainties in the properties of planetary …

Formation of planetary systems by pebble accretion and migration: growth of gas giants

B Bitsch, A Izidoro, A Johansen, SN Raymond… - Astronomy & …, 2019 - aanda.org
Giant planets migrate though the protoplanetary disc as they grow their solid core and attract
their gaseous envelope. Previously, we have studied the growth and migration of an isolated …

The Disc Miner-II. Revealing gas substructures and kinematic signatures from planet-disc interaction through line profile analysis

AF Izquierdo, L Testi, S Facchini, GP Rosotti… - Astronomy & …, 2023 - aanda.org
Detecting planets in the early stages of formation is key to reconstructing the history and
diversity of fully developed planetary systems. The aim of this work is to identify potential …

Predicted diversity in water content of terrestrial exoplanets orbiting M dwarfs

T Kimura, M Ikoma - Nature Astronomy, 2022 - nature.com
Exoplanet surveys around M dwarfs have detected a growing number of exoplanets with
Earth-like insolation. It is expected that some of those planets are rocky planets with the …

Highly structured disk around the planet host PDS 70 revealed by high-angular resolution observations with ALMA

M Keppler, R Teague, J Bae, M Benisty… - Astronomy & …, 2019 - aanda.org
Context. Imaged in the gap of a transition disk and found at a separation of about 195 mas (~
22 au) from its host star at a position angle of about 155°, PDS 70 b is the most robustly …
