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…
