Different Modes of Star Formation: Gravitational Collapse of Magnetically Subcritical Cloud
Masahiro N. Machida, Koki Higuchi, Satoshi Okuzumi
Star formation in magnetically subcritical clouds is investigated using a three-dimensional non-ideal magneto-hydrodynamics simulation. Since rapid cloud collapse is suppressed unt…
Electron Heating and Saturation of Self-regulating Magnetorotational Instability in Protoplanetary Disks
Shoji Mori, Takayuki Muranushi, Satoshi Okuzumi +1
Magnetorotational instability (MRI) has a potential to generate the vigorous turbulence in protoplanetary disks, although its turbulence strength and accretion stress remains debat…
Harvesting the decay energy of Al to drive lightning discharge in protoplanetary discs
Anders Johansen, Satoshi Okuzumi
Chondrules in primitive meteorites likely formed by recrystallisation of dust aggregates that were flash-heated to nearly complete melting. Chondrules may represent the building bl…
What pebbles are made of: Interpretation of the V883 Ori disk
Djoeke Schoonenberg, Satoshi Okuzumi, Chris W. Ormel
Recently, an Atacama Large Millimeter/submillimeter Array (ALMA) observation of the water snow line in the protoplanetary disk around the FU Orionis star V883 Ori was reported. The…
Satellitesimal Formation via Collisional Dust Growth in Steady Circumplanetary Disks
Yuhito Shibaike, Satoshi Okuzumi, Takanori Sasaki +1
The icy satellites around Jupiter are considered to have formed in a circumplanetary disk. While previous models focused on the formation of satellites starting from satellitesimal…
Dust Growth and Magnetic Fields: from Cores to Disks (even down to Planets)
Yasuhiro Hasegawa, Jennifer I-Hsiu Li, Satoshi Okuzumi
The recent rapid progress in observations of circumstellar disks and extrasolar planets has reinforced the importance of understanding an intimate coupling between star and planet…
Magnetically Induced Disk Winds and Transport in the HL Tau Disk
Yasuhiro Hasegawa, Satoshi Okuzumi, Mario Flock +1
The mechanism of angular momentum transport in protoplanetary disks is fundamental to understand the distributions of gas and dust in the disks. The unprecedented, high spatial res…
Effect of dust radial drift on viscous evolution of gaseous disk
Kazuhiro D. Kanagawa, Takahiro Ueda, Takayuki Muto +1
The total amount of dust (or "metallicity") and the dust distribution in protoplanetary disks are crucial for planet formation. Dust grains radially drift due to gas--dust friction…
The impact of the Hall effect during cloud core collapse:implications for circumstellar disk evolution
Yusuke Tsukamoto, Satoshi Okuzumi, Kazunari Iwasaki +2
We perform three-dimensional radiation non-ideal magnetohydrodynamics simulations and investigate the impact of the Hall effect on the angular momentum evolution in the collapsing…
Analytic Expressions for the Inner-Rim Structure of Passively Heated Protoplanetary Disks
Takahiro Ueda, Satoshi Okuzumi, Mario Flock
We analytically derive the expressions for the structure of the inner region of protoplanetary disks based on the results from the recent hydrodynamical simulations. The inner part…
A Condensation-Coalescence Cloud Model for Exoplanetary Atmospheres: Formulation and Test Applications to Terrestrial and Jovian Clouds
Kazumasa Ohno, Satoshi Okuzumi
A number of transiting exoplanets have featureless transmission spectra that might suggest the presence of clouds at high altitudes. A realistic cloud model is necessary to underst…
