Dust-evacuated Zones near Massive Stars: Consequences of Dust Dynamics on Star-forming Regions
The Astrophysical JournalStars form within dense cores composed of both gas and dust within molecular clouds. However, despite the crucial role that dust plays in the star formation process, its dynamics is frequently overlooked, with the common assumption being a constant ...

Cloud–Cloud Collision and Cluster Formation in the W5-NW Complex
The Astronomical JournalWe present a detailed structural and gas kinematic study of the star-forming complex W5-NW. A cloud–cloud collision scenario unravels with evidence of collision-induced star and cluster formation.

An S-shaped Filament Formed Due to Cloud–Cloud Collision in Molecular Cloud G178.28-00.61
The Astrophysical Journal Supplement SeriesWe present compelling observational evidence supporting G178.28-00.61 as an early-stage candidate for cloud–cloud collision (CCC), with indications of the formation of an S-shaped filament, evenly separated dense cores, and young star clusters.

Detection of an Explosive Outflow in G34.26+0.15
The Astronomical JournalThis paper reports on the detection of a likely explosive outflow in the high-mass star-forming complex G34.26+0.15, adding to the small number (six) of explosive outflows detected so far.

Dynamical evolution and molecular abundances of interstellar clouds
The Astrophysical Journal, 1991 Dynamical models are presented that start with interstellar gas in an initial diffuse state and consider their gravitational collapse and the formation of dense cores. Frozen-in tangled magnetic fields are included to mimic forces that might oppose gravitational contraction and whose effectiveness may increase with increasing core densities.

An Anisotropic Plasma Model of the Heliospheric Interface
The Astrophysical JournalWe present a pioneering model of the interaction between the solar wind and the surrounding interstellar medium that includes the possibility of different pressures in directions parallel and perpendicular to the magnetic field.
