Context. The origin of the chemical diversity observed around low-mass protostars probably resides in the earliest history of these systems.
Aims. We aim to investigate the impact of protostellar feedback on the chemistry and grain growth in the ...

Abstract
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 show a fast algorithm for solving the Poisson equation on a nested grid. The nested grid consists of uniform grids having potentials us to compute the gravitational potential of compact bodies embedded in a less dense cloud. The computation loa...
We investigate the stability of a gravitationally collapsing iron core against nonspherical perturbation. The gravitationally collapsing iron core is approximated by a similarity solution for a dynamically collapsing polytropic gas sphere. We find...
We show three-dimensional numerical simulations in which stars form sequentially in a filamentary molecular cloud. The star formation is triggered by expansion of an H II region. The H II region is distant from the filamentary cloud at the initial...

We discuss the stability of dynamically collapsing gas spheres. We use a similarity solution for a dynamically collapsing sphere as the unperturbed state. In the similarity solution the gas pressure is approximated by a polytrope of P = K rho(gamm...
We show two-dimensional numerical simulations of the gravitational collapse of rotating gas clouds. We assume the polytropic equation of state, P = K rho(gamma), to take account of the temperature change during the collapse. Our numerical simulati...
