, 2010 Most phases of the interstellar medium contain neutral atoms in addition to ions and electrons. This introduces differences in plasma physics processes in those media relative to the solar corona and the solar wind at a heliocentric distance of 1 ...

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.

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.

Properties of interstellar wind leading to shape morphology of the dust surrounding HD 61005
, 2017 A structure formed by dust particles ejected from the debris ring around HD 61005 is observed in the scattered light. The main aim here is to constrain interstellar wind parameters that lead to shape morphology in the vicinity of HD 61005 using currently

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.

High-drag Interstellar Objects and Galactic Dynamical Streams
The Astrophysical Journal Letters, 2019 Abstract The nature of 1I/’Oumuamua (henceforth, 1I), the first interstellar object (ISO) known to pass through the solar system, remains mysterious. Feng & Jones noted that the incoming 1I velocity vector “at infinity” ( ) is close to the motion of the Pleiades ...

Superaromatics: The key to a unified cosmic dust theory [PDF]
The theory of Superaromatics, the key to a unified cosmic dust theory, was constructed by analyzing several thousand astronomical features covering every major aspect of astrophysics and astrochemistry relating to dust.

Examining Turbulence in Galactic Molecular Clouds. I. A Statistical Analysis of Velocity Structures
The Astrophysical JournalWe present a systematic analysis of the velocity structure functions (VSFs) of 167 molecular clouds with angular sizes greater than ~176 arcmin ^2 in three sectors of the Galactic midplane.

The consequence of dynamics in the interstellar medium
The interstellar medium (ISM) of the Milky Way is in a constant state of motion. Between the large scale motions of galactic dynamics and the turbulence within giant molecular clouds (GMCs), the evolution of the ISM is guided by its underlying motions. The large scale dynamics perturb the diffuse warm neutral medium (WNM) of the Milky Way, starting the
