Gas Giant Formation with Small Cores Triggered by Envelope Pollution by Icy Planetesimals
Yasunori Hori, Masahiro Ikoma
We have investigated how envelope pollution by icy planetesimals affects the critical core mass for gas giant formation and the gas accretion time-scales. In the core-accretion mod…
Planet Engulfment by ~1.5-3 Solar-Mass Red Giants
M. Kunitomo, M. Ikoma, B. Sato +2
Recent radial-velocity surveys for GK clump giants have revealed that planets also exist around ~1.5-3 Msun stars. However, no planets have been found inside 0.6 AU around clump gi…
Orbital Evolution of Planets around Intermediate-Mass Giants
M. Kunitomo, M. Ikoma, B. Sato +2
Around low- and intermediate-mass (1.5-3 M_sun) red giants, no planets have been found inside 0.6 AU. Such a paucity is not seen in the case of 1 M_sun main sequence stars. In this…
Laser-Shock Compression and Hugoniot Measurements of Liquid Hydrogen to 55 GPa
T. Sano, N. Ozaki, T. Sakaiya +19
The principal Hugoniot for liquid hydrogen was obtained up to 55 GPa under laser-driven shock loading. Pressure and density of compressed hydrogen were determined by impedance-matc…
Self-Consistent Model Atmospheres and the Cooling of the Solar System's Giant Planets
J. J. Fortney, M. Ikoma, N. Nettelmann +2
We compute grids of radiative-convective model atmospheres for Jupiter, Saturn, Uranus, and Neptune over a range of intrinsic fluxes and surface gravities. The atmosphere grids ser…
