Characterizing the physical properties of dust grains in a protoplanetary disk is critical to comprehending the planet formation process. Our study presents Atacama Large Millimeter/submillimeter Array (ALMA) high-resolution observation...
We investigate the stability of a similarity solution for a gravitationally collapsing isothermal sphere by means of a normal-mode analysis. When the central density increases in proportion to rho(c) proportional to (t(0) - t)(-2), the bar mode gr...
We investigated the dynamical collapse of a molecular cloud core with three-dimensional numerical simulations. Our simulations show that an initially spherical core produces a bar or disk during its dynamical collapse. The disk and bar formation i...
Taking self-gravity into account, we investigated the stability of the interstellar medium in which the circularly polarized Alfven wave travels with large amplitude. The interstellar medium suffers from two types of instabilities: the Jeans insta...
