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 three-dimensional numerical simulations on the core collapse of a rotating massive star threaded by strong magnetic fields. The initial magnetic field is nearly uniform in the core and inclined by 60° with respect to the rotation axis. A t...

Subsequent to Paper I, the evolution and fragmentation of a rotating magnetized cloud are studied with use of three-dimensional magnetohydrodynamic nested grid simulations. After the isothermal runaway collapse, an adiabatic gas forms a protostell...

The birth of very massive stars is not well understood(1-3), in contrast to the formation process of low-mass stars like our Sun(4,5). It is not even clear that massive stars can form as single entities; rather, they might form through the mergers...
We reexamine accretion onto a protobinary based on two-dimensional numerical simulations with high spatial resolution. We focus our attention on the ratio of the primary and secondary accretion rates. Fifty-eight models are made for studying the d...
