Multi-Phase Dynamics of Magnetized Interstellar Medium [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractThe recent progress in our understanding of the dynamics of muliti-phase interstellar medium (ISM) is reviewed. Non-linear perturbations (e.g., shock waves or time-dependent radiation field) lead to the interchange between warm phase and cold phase via thermal instability.

Journal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.New calculations have been applied to the pyrolysis of pyrrole under shock‐tube conditions and to the radical‐radical reaction between allyl and •CN at low temperature and pressure, using the same mechanistic scheme for both. ABSTRACT The pyrolysis of pyrrole has previously been studied in shock‐tube experiments and in jet‐stirred reactors. The results

Nuclear interactions of low-energy cosmic rays with the interstellar medium
, 2011 Cosmic rays of kinetic energies below ~1 GeV per nucleon are thought to play a key role in the chemistry and dynamics of the interstellar medium. They are also thought to be responsible for nucleosynthesis of the light elements Li, Be, and B.

The Dynamics of Reading Genre Fiction: Researching and Teaching Interpretive Practices
Reading Research Quarterly, Volume 61, Issue 2, April/May/June 2026.Conceptual model positioning genre fiction as a site for studying how narrative form organizes reader interpretation, identifying four dynamics—iterability, narrative interest, serialization, and spectacle—to guide empirical research on reading processes.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Xenon (Xe) is a heavy noble gas with intriguing chemical properties, such as having several stable isotopes and the ability to form compounds under extreme conditions. Despite the predictions based on cosmochemical models that suggest xenon should be relatively abundant in planetary reservoirs, empirical data indicate a significant depletion ...

A Catalogue of Interstellar Material Delivery from Nearby Debris Disks
The Planetary Science JournalWe modeled the trajectories of material ejected from 20 nearby debris disk stars, including ϵ Eridani (Ran), Vega, Fomalhaut, and β Pictoris, within a simulated Milky Way potential in order to quantify their contribution to the population of interstellar

Galactic civilizations: Population dynamics and interstellar diffusion [PDF]
The interstellar diffusion of galactic civilizations is reexamined by potential theory; both numerical and analytical solutions are derived for the nonlinear partial differential equations which specify a range of relevant models, drawn from blast wave ...

Charging of Aggregate Grains in Astrophysical Environments
, 2013 The charging of dust grains in astrophysical environments has been investigated with the assumption these grains are homogeneous spheres. However, there is evidence which suggests many grains in astrophysical environments are irregularly-shaped ...
