Dust ring and gap formation by gas flow induced by low-mass planets embedded in protoplanetary disks . Time-dependent model
Ayumu Kuwahara, Michiel Lambrechts, Hiroyuki Kurokawa +2
The observed dust rings and gaps in protoplanetary disks could be imprints of forming planets. Even low-mass planets in the one-to-ten Earth-mass regime, that do not yet carve deep…
Delivery of gas onto the circumplanetary disk of giant planets: Planetary-mass dependence of the source region of accreting gas and mass accretion rate
Natsuho Maeda, Keiji Ohtsuki, Takayuki Tanigawa +2
Gas accretion onto the circumplanetary disks and the source region of accreting gas are important to reveal dust accretion that leads to satellite formation around giant planets. W…
Dust ring and gap formation by gas flow induced by low-mass planets embedded in protoplanetary disks . Steady-state model
Ayumu Kuwahara, Hiroyuki Kurokawa, Takayuki Tanigawa +1
Recent high-spatial-resolution observations have revealed dust substructures in protoplanetary disks such as rings and gaps, which do not always correlate with gas. Because radial…
Eccentric gap induced by a super-Jupiter mass planet
Yuki A. Tanaka, Kazuhiro D. Kanagawa, Hidekazu Tanaka +1
A giant planet embedded in a protoplanetary disk opens a gap by tidal interaction, and properties of the gap strongly depend on the planetary mass and disk parameters. Many numeric…
Accretion Properties of PDS 70b with MUSE
Jun Hashimoto, Yuhiko Aoyama, Mihoko Konishi +4
We report a new evaluation of the accretion properties of PDS~70b obtained with VLT/MUSE. The main difference from previous studies in Haffert et al. (2019) and Aoyama & Ikoma (201…
Final Masses of Giant Planets III: Effect of Photoevaporation and a New Planetary Migration Model
Hidekazu Tanaka, Kiyoka Murase, Takayuki Tanigawa
We herein develop a new simple model for giant planet formation, which predicts the final mass of a giant planet born in a given disk, by adding the disk mass loss due to photoevap…
Impacts of dust feedback on a dust ring induced by a planet in a protoplanetary disk
Kazuhiro D. Kanagawa, Takayuki Muto, Satoshi Okuzumi +3
When a planet forms a deep gap in a protoplanetary disk, dust grains cannot pass through the gap. As a consequence, the density of the dust grains can increase up to the same level…
Theoretical Model of Hydrogen Line Emission from Accreting Gas Giants
Yuhiko Aoyama, Masahiro Ikoma, Takayuki Tanigawa
Progress in understanding of giant planet formation has been hampered by a lack of observational constraints to growing protoplanets. Recently, detection of an Hα-emission excess v…
Slowing Down Type II Migration of Gas Giants to Match Observational Data
Shigeru Ida, Hidekazu Tanaka, Anders Johansen +2
The mass and semimajor axis distribution of gas giants in exoplanetary systems obtained by radial velocity surveys shows that super-jupiter-mass planets are piled up at > 1 au, whi…
Suppression of atmospheric recycling of planets embedded in a protoplanetary disc by buoyancy barrier
Hiroyuki Kurokawa, Takayuki Tanigawa
The ubiquity of super-Earths poses a problem for planet formation theory to explain how they avoided becoming gas giants. Rapid recycling of the envelope gas of planets embedded in…
Constraining accretion signatures of exoplanets in the TW Hya transitional disk
Taichi Uyama, Takayuki Tanigawa, Jun Hashimoto +4
We present a near-infrared direct imaging search for accretion signatures of possible protoplanets around the young stellar object (YSO) TW Hya, a multi-ring disk exhibiting eviden…
Modeling of deep gaps created by giant planets in protoplanetary discs
K. D. Kanagawa, H. Tanaka, T. Muto +1
A giant planet embedded in a protoplanetary disk creates a gap. This process is important for both theory and observations. Using results of a survey for a wide parameter range wit…
Final Masses of Giant Planets II: Jupiter Formation in a Gas-Depleted Disk
Takayuki Tanigawa, Hidekazu Tanaka
Firstly, we study the final masses of giant planets growing in protoplanetary disks through capture of disk gas, by employing an empirical formula for the gas capture rate and a sh…
