Interstellar Dust in the Solar System: Model versus In-Situ Spacecraft Data
, 2019 In the early 1990s, contemporary interstellar dust penetrating deep into the heliosphere was identified with the in-situ dust detector on board the Ulysses spacecraft.

Where Does the Energy Go during the Interstellar NH3 Formation on Water Ice? A Computational Study
The Astrophysical Journal, 2023 In the coldest (10–20 K) regions of the interstellar medium, the icy surfaces of interstellar grains serve as solid-state supports for chemical reactions.

Structure of dynamical condensation fronts in the interstellar medium [PDF]
Monthly Notices of the Royal Astronomical Society, 2012 In this paper, we investigate the structure of condensation fronts from warm diffuse gas to cold neutral medium (CNM) under the plane parallel geometry. The solutions have two parameters, the pressure of the CNM and the mass flux across the transition front, and their ranges are much wider than previously thought.

Physical and Dynamical Conditions in Interstellar Clouds [PDF]
Symposium - International Astronomical Union, 1980 The most far-reaching result to come from the study of interstellar molecules has been the recognition of a new class of galactic structures - molecular clouds. These clouds appear to contain most of the mass of the interstellar medium and are the objects from which new stars are formed.

On the formation of density filaments in the turbulent interstellar medium [PDF]
, 2019 This study is motivated by recent observations on ubiquitous interstellar density filaments and guided by modern theories of compressible magnetohydrodynamic (MHD) turbulence. The interstellar turbulence shapes the observed density structures.

Interrelations Between Astrochemistry and Galactic Dynamics
Frontiers in Astronomy and Space Sciences, 2021 This paper presents a review of ideas that interconnect astrochemistry and galactic dynamics. Since these two areas are vast and not recent, each one has already been covered separately by several reviews.

Dynamical evolution of a supernova driven turbulent interstellar medium [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractIt is shown that a number of key observations of the Galactic ISM can be understood, if it is treated as a highly compressible and turbulent medium, energized predominantly by supernova explosions (and stellar winds). We have performed extensive numerical high resolution 3D hydrodynamical and magnetohydrodynamical simulations with adaptive mesh
