Eccentric gap induced by a super-Jupiter mass planet
Yuki A. Tanaka, Kazuhiro D. Kanagawa, Hidekazu Tanaka +1
A giant planet embedded in a protoplanetary disk opens a gap by tidal interaction, and properties of the gap strongly depend on the planetary mass and disk parameters. Many numeric…
Grain Growth in Escaping Atmospheres: Implications for the Radius Inflation of Super-Puffs
Kazumasa Ohno, Yuki A. Tanaka
Super-puffs -- low-mass exoplanets with extremely low bulk density -- are attractive targets for exploring their atmospheres and formation processes. Recent studies suggested that…
Investigation of coronal properties of X-ray bright G-dwarf stars based on the solar surface magnetic field -- corona relation
Shinsuke Takasao, Ikuyuki Mitsuishi, Takuma Shimura +4
We investigated the coronal properties of G-dwarf stars including the Sun over a wide range of X-ray luminosity ( to …
Pebble accretion in class 0/I YSOs as a possible pathway for early planet formation
Yuki A. Tanaka, Yusuke Tsukamoto
Recent theoretical works suggest that the pebble accretion process is important for planet formation in protoplanetary disks, because it accelerates the growth of planetary cores.…
Broadening of Cyclotron Resonance Conditions in the Relativistic Interaction of an Intense Laser with Overdense Plasmas
Takayoshi Sano, Yuki Tanaka, Natsumi Iwata +4
The interaction of dense plasmas with an intense laser under a strong external magnetic field has been investigated. When the cyclotron frequency for the ambient magnetic field is…
An evaporating planet in the wind: stellar wind interactions with the radiatively braked exosphere of GJ436 b
Vincent Bourrier, Alain Lecavelier des Etangs, David Ehrenreich +2
The warm Neptune GJ436b was observed with HST/STIS at three different epochs in the stellar Ly-alpha line, showing deep, repeated transits caused by a giant exosphere of neutral hy…
Atmospheric Escape by Magnetically Driven Wind from Gaseous Planets II --Effects of Magnetic Diffusion--
Yuki A. Tanaka, Takeru K. Suzuki, Shu-ichiro Inutsuka
We investigate roles of Alfvenic waves in the weakly-ionized atmosphere of hot Jupiters by carrying out non-ideal magnetohydrodynamic (MHD) simulations with Ohmic diffusion in one-…
Atmospheric escape by magnetically driven wind from gaseous planets
Yuki A. Tanaka, Takeru K. Suzuki, Shu-ichiro Inutsuka
We calculate the mass loss driven by MHD waves from hot Jupiters by using MHD simulations in one-dimensional flux tubes. If a gaseous planet has magnetic field, MHD waves are excit…
