Planet formation on solar system scales
Francesco Zagaria, Andrés F. Izquierdo, Jaehan Bae +32
Giant planets are often regarded as primordial protoplanetary "architects". Their formation and interactions with planetesimals and other planets during and after the protoplanetar…
Interpreting ALMA Multiwavelength Continuum Observations of PDS 70 c: An Optically Thick Dust Ring in the Circumplanetary Disk
Yuhito Shibaike, Satoshi Okuzumi, Takahiro Ueda +2
Giant planets form small gas disks, called circumplanetary disks (CPDs), during gas accretion. The CPD of PDS 70 c has been detected by the Atacama Large Millimeter/submillimeter A…
Active moons in our Solar System and beyond -- Io, Europa, Enceladus, Triton, and exomoons
Caroline Haslebacher, Emeline Bolmont, Marco Cilibrasi +19
The outgassing signatures of Io, Europa, Enceladus, Triton, and Io-like exomoons are the focus of this review chapter. The rocky volcanic world of Io is unique in our Solar System,…
A Protoplanet Candidate in the PDS 66 Disk Indicated by Silicon Sulfide Isotopologues
Tomohiro C. Yoshida, Felipe Alarcón, Jaehan Bae +11
Despite observational progress in planet formation, the stage in which planetesimals grow into planets remains poorly understood. During this phase, protoplanets may develop gaseou…
Origin of Ganymede and the Galilean Moons
Yuhito Shibaike, Yann Alibert
Ganymede and the Galilean moons formed in a small gas disc around the gas-accreting proto-Jupiter, known as the circum-Jovian disc (CJD). The formation process of the satellites oc…
Predictions of dust continuum observations of circumplanetary disks with ngVLA: A case study of PDS 70 c
Yuhito Shibaike, Takahiro Ueda, Misato Fukagawa
A gas giant forms a small gas disk called a "circumplanetary disk (CPD)" around the planet during its gas accretion process. The small gas disk contains dust particles like those i…
Partial Differentiation of Callisto as Possible Evidence for Pebble Accretion
Yuhito Shibaike
"Planetesimal or pebble" is one of the most fundamental open questions in planet formation theory. Similarly, "satellitesimal or pebble" remains unsettled regarding the formation o…
Understanding the formation of Saturn's regular moons in the context of giant planet moons formation scenarios
Michel Blanc, Aurélien Crida, Yuhito Shibaike +7
This article explores the different formation scenarios of the Kronian moons system in the context of a highly dissipative Saturn, with the objective of identifying the most likely…
Predictions of Dust Continuum Emission from a Potential Circumplanetary Disk: A Case Study of the Planet Candidate AB Aurigae b
Yuhito Shibaike, Jun Hashimoto, Ruobing Dong +3
Gas accreting planets embedded in protoplanetary disks are expected to show dust thermal emission from their circumplanetary disks (CPDs). However, a recently reported gas accretin…
Outflow Driven by a Protoplanet Embedded in the TW Hya Disk
Tomohiro C. Yoshida, Hideko Nomura, Charles J. Law +4
Gas giant planets are formed by gas accretion onto planetary cores in protoplanetary disks. However, direct evidence of this process is still lacking, limiting our understanding of…
Constraints on PDS 70 b and c from the dust continuum emission of the circumplanetary discs considering in situ dust evolution
Yuhito Shibaike, Christoph Mordasini
The young T Tauri star PDS 70 has two gas accreting planets sharing one large gap in a pre-transitional disc. Dust continuum emission from PDS 70 c has been detected by Atacama Lar…
Delivery of Dust Particles from Protoplanetary Disks onto Circumplanetary Disks of Giant Planets
Natsuho Maeda, Keiji Ohtsuki, Ryo Suetsugu +3
Principal regular satellites of gas giants are thought to be formed by the accumulation of solid materials in circumplanetary disks (CPDs). While there has been significant progres…
Planetesimal formation at the gas pressure bump following a migrating planet II. Effects of dust growth
Yuhito Shibaike, Yann Alibert
Planetesimal formation is still mysterious. One of the ways to form planetesimals is to invoke a gas pressure bump in a protoplanetary disc. In our previous paper, we propose a new…
Effective dust growth in laminar circumplanetary discs with magnetic wind-driven accretion
Yuhito Shibaike, Shoji Mori
It has been considered that large satellites around gas planets form in-situ circumplanetary discs (CPDs). However, dust particles supplied into CPDs drift toward the central plane…
Planetesimal formation at the gas pressure bump following a migrating planet I. Basic characteristics of the new formation model
Yuhito Shibaike, Yann Alibert
To avoid known difficulties in planetesimal formation such as the drift or fragmentation barriers, many scenarios have been proposed. However, in these scenarios, planetesimals for…
The Galilean Satellites Formed Slowly from Pebbles
Yuhito Shibaike, Chris W. Ormel, Shigeru Ida +2
It is generally accepted that the four major (Galilean) satellites formed out of the gas disk that accompanied Jupiter's formation. However, understanding the specifics of the form…
Photophoresis in the circumjovian disk and its impact on the orbital configuration of the Galilean satellites
Sota Arakawa, Yuhito Shibaike
Jupiter has four large regular satellites called the Galilean satellites: Io, Europa, Ganymede, and Callisto. The inner three of the Galilean satellites orbit in a 4:2:1 mean motio…
Possibility of Concentration of Non-volatile Species near the Surface of Comet 67P/Churyumov-Gerasimenko
Taiki Suzuki, Yoshiharu Shinnaka, Liton Majumdar +4
The cometary materials are thought to be the reservoir of primitive materials in the Solar System. The recent detection of glycine and CHNH by the ROSINA mass spectrometer…
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…
Satellitesimal Formation via Collisional Dust Growth in Steady Circumplanetary Disks
Yuhito Shibaike, Satoshi Okuzumi, Takanori Sasaki +1
The icy satellites around Jupiter are considered to have formed in a circumplanetary disk. While previous models focused on the formation of satellites starting from satellitesimal…
Excavation and Melting of the Hadean Continental Crust by Late Heavy Bombardment
Yuhito Shibaike, Takanori Sasaki, Shigeru Ida
No Hadean rocks have ever been found on Earth's surface except for zircons---evidence of continental crust, suggesting that Hadean continental crust existed but later disappeared.…
