Shock-Generating Planetesimals Perturbed by a Giant Planet in a Gas Disk
M. Nagasawa, K. K. Tanaka, H. Tanaka +3
We examined the excitations of planetesimals caused by the resonances of a giant planet in a protoplanetary gas disk. The highly excited planetesimals generate bow shocks, the mech…
Water ice at the surface of HD 100546 disk
M. Honda, T. Kudo, S. Takatsuki +6
We made near infrared multicolor imaging observations of a disk around Herbig Be star HD100546 using Gemini/NICI. K (2.2\,m), HO ice (3.06\,m), and L'(3.8\,m) disk ima…
Revisiting Jovian-Resonance Induced Chondrule Formation
M. Nagasawa, K. K. Tanaka, H. Tanaka +3
It is proposed that planetesimals perturbed by Jovian mean-motion resonances are the source of shock waves that form chondrules. It is considered that this shock-induced chondrule…
Mass-Loss Evolution of Close-In Exoplanets: Evaporation of Hot Jupiters and the Effect on Population
Hiroyuki Kurokawa, Taishi Nakamoto
During their evolution, short-period exoplanets may lose envelope mass through atmospheric escape owing to intense XUV (X-ray and extreme ultraviolet) radiation from their host sta…
Formation of Cosmic Crystals in Highly-Supersaturated Silicate Vapor Produced by Planetesimal Bow Shocks
H. Miura, K. K. Tanaka, T. Yamamoto +4
Several lines of evidence suggest that fine silicate crystals observed in primitive meteorite and interplanetary dust particles (IDPs) nucleated in a supersaturated silicate vapor…
