Double Lynden-Bell Structure of Low-Energy Quasi-Stationary Distributions in the Hamiltonian Mean-Field Model
Eiji Konishi, Masa-aki Sakagami
In the Hamiltonian mean-field model, we study the core-halo structure of low-energy quasi-stationary states under unsteady water-bag type initial conditions. The core-halo structur…
Electrostatic Barrier against Dust Growth in Protoplanetary Disks. I. Classifying the Evolution of Size Distribution
Satoshi Okuzumi, Hidekazu Tanaka, Taku Takeuchi +1
Collisional growth of submicron-sized dust grains into macroscopic aggregates is the first step of planet formation in protoplanetary disks. These grains are expected to carry nonz…
Electrostatic Barrier against Dust Growth in Protoplanetary Disks. II. Measuring the Size of the "Frozen" Zone
Satoshi Okuzumi, Hidekazu Tanaka, Taku Takeuchi +1
Coagulation of submicron-sized dust grains into porous aggregates is the initial step of dust evolution in protoplanetary disks. Recently, it has been pointed out that negative cha…
Numerical Modeling of the Coagulation and Porosity Evolution of Dust Aggregates
Satoshi Okuzumi, Hidekazu Tanaka, Masa-aki Sakagami
Porosity evolution of dust aggregates is crucial in understanding dust evolution in protoplanetary disks. In this study, we present useful tools to study the coagulation and porosi…
Probing non-tensorial polarizations of stochastic gravitational-wave backgrounds with ground-based laser interferometers
Atsushi Nishizawa, Atsushi Taruya, Kazuhiro Hayama +2
In a general metric theory of gravitation in four dimensions, six polarizations of a gravitational wave are allowed: two scalar and two vector modes, in addition to two tensor mode…
Electric charging of dust aggregates and its effect on dust coagulation in protoplanetary disks
Satoshi Okuzumi
Mutual sticking of dust aggregates is the first step toward planetesimal formation in protoplanetary disks. In spite that the electric charging of dust particles is well recognized…
