Distribution of Chemically-Processed Dust in a Viscously Evolving Protoplanetary Disk: Application to Crystalline Silicates in Comets
Lily Ishizaki, Shogo Tachibana, Shigeru Ida
Dust particles undergo chemical reactions in protoplanetary disks according to their environments, producing compositional diversity in planetary materials. Extraterrestrial record…
Large planets may not form fractionally large moons
Miki Nakajima, Hidenori Genda, Erik Asphaug +1
One of the unique aspects of Earth is that it has a fractionally large Moon, which is thought to have formed from a Moon-forming disk generated by a giant impact. The Moon stabiliz…
Effective reaction temperatures of irreversible dust chemical reactions in a protoplanetary disk
Lily Ishizaki, Shogo Tachibana, Tamami Okamoto +2
Dust particles in protoplanetary disks experience various chemical reactions under different physicochemical conditions through their accretion and diffusion, which results in the…
Revisiting Planetary Systems in Okayama Planet Search Program: A new long-period planet, RV astrometry joint analysis, and multiplicity-metallicity trend around evolved stars
Huan-Yu Teng, Bun'ei Sato, Masayuki Kuzuhara +15
In this study, we revisit 32 planetary systems around evolved stars observed within the framework of the Okayama Planet Search Program and its collaborative framework of the EAPS-N…
Planetesimals drifting through dusty and gaseous white dwarf debris discs: Types I, II and III-like migration
Dimitri Veras, Shigeru Ida, Evgeni Grishin +2
The suite of over 60 known planetary debris discs which orbit white dwarfs, along with detections of multiple minor planets in these systems, motivate investigations about the migr…
Spin of protoplanets generated by pebble accretion: Influences of protoplanet-induced gas flow
Kohsuke Takaoka, Ayumu Kuwahara, Shigeru Ida +1
We investigate the spin state of a protoplanet during the pebble accretion influenced by the gas flow in the gravitational potential of the protoplanet and how it depends on the pl…
