Planetesimal Formation at the Boundary Between Steady Super/Sub-Keplerian Flow Created by Inhomogeneous Growth of Magnetorotational Instability
Mariko T. Kato, Masaki Fujimoto, Shigeru Ida
We have studied formation of planetesimals at a radial pressure bump in a protoplanetary disk created by radially inhomogeneous magnetorotational instability (MRI), through three-d…

`Island Surfing' Mechanism of Electron Acceleration During Magnetic Reconnection
M. Oka, M. Fujimoto, I. Shinohara +1
One of the key unresolved problems in the study of space plasmas is to explain the production of energetic electrons as magnetic field lines `reconnect' and release energy in a exp…

Non-thermal Electrons at the Earth's Bow Shock: A `Gradual' Event
M. Oka, T. Terasawa, M. Fujimoto +6
Earth's bow shock is known to produce non-thermal electrons which are generally observed as a `spike' in their flux profile. Here, in this paper, we present an analysis of electron…
