Ring formation by coagulation of dust aggregates in early phase of disk evolution around a protostar
Satoshi Ohashi, Hiroshi Kobayashi, Riouhei Nakatani +6
Ring structures are observed by (sub-)millimeter dust continuum emission in various circumstellar disks from early stages of Class 0 and I to late stage of Class II young stellar o…
Radiation hydrodynamics simulations of protoplanetary disks: Stellar mass dependence of the disk photoevaporation rate
Ayano Komaki, Riouhei Nakatani, Naoki Yoshida
Recent multi-wavelength observations suggest that inner parts of protoplanetary disks (PPDs) have shorter lifetimes for heavier host stars. Since PPDs around high-mass stars are ir…
Hydrodynamical simulations of protoplanetary disks including irradiation of stellar photons. I. Resolution study for Vertical Shear Instability (VSI)
Lizxandra Flores-Rivera, Mario Flock, Ryohei Nakatani
In recent years hydrodynamical (HD) models have become important to describe the gas kinematics in protoplanetary disks, especially in combination with models of photoevaporation a…
Photoevaporation of Grain-Depleted Protoplanetary Disks around Intermediate-Mass Stars: Investigating Possibility of Gas-Rich Debris Disks as Protoplanetary Remnants
Riouhei Nakatani, Hiroshi Kobayashi, Rolf Kuiper +2
Debris disks are classically considered to be gas-less systems, but recent (sub)millimeter observations have detected tens of those with rich gas content. The origin of the gas com…
Photoevaporation of Minihalos during Cosmic Reionization: Primordial and Metal-Enriched Halos
Riouhei Nakatani, Anastasia Fialkov, Naoki Yoshida
The density distribution of the inter-galactic medium is an uncertain but highly important issue in the study of cosmic reionization. It is expected that there are abundant gas clo…
Atmospheric Escape of Close-in Giants around Hot Stars: Far-Ultraviolet Radiation and Photoelectric Heating Effect
Hiroto Mitani, Riouhei Nakatani, Naoki Yoshida
Atmospheric escape is an important process that controls the long-term evolution of close-in planets. We perform radiation hydrodynamics simulations of photo-evaporation of exoplan…
Substructure Formation in a Protostellar Disk of L1527 IRS
Riouhei Nakatani, Hauyu Baobab Liu, Satoshi Ohashi +5
We analyze multi-frequency, high-resolution continuum data obtained by ALMA and JVLA to study detailed structure of the dust distribution in the infant disk of a Class~0/I source,…
