Where the stellar wind impinges the interstellar medium

Conference: Physics of Extreme Massive Stars
Massive stars have strong radiation-driven winds, losing part of their mass. Where these winds encounter the interstellar medium, a separatrix surface can form, called astropause. The astropause separates the stellar wind region, the astrosphere, from the outer streaming interstellar medium. At the apex of the astropause the stagnation point is located,

Spectroscopic Investigation of Thioacrolein by Variational and Perturbational Approaches

Journal of Computational Chemistry, Volume 47, Issue 10, 15 April 2026.
The vibrational and rotational spectra of trans and cis‐thioacrolein were studied by high levels of electronic and vibrational structure theory. Comparisons with experimental results are provided for several molecular quantities. ABSTRACT The vibrational spectra of trans and cis‐thioacrolein have been studied by 2nd order vibrational perturbation ...

Spherical Harmonic Representation of Energetic Neutral Atom Flux Components Observed by IBEX

The Astrophysical Journal Supplement Series, 2023
The Interstellar Boundary Explorer (IBEX) images the heliosphere by observing energetic neutral atoms (ENAs). The IBEX-Hi instrument on board IBEX provides full-sky maps of ENA fluxes produced in the heliosphere and very local interstellar medium through

Prebiotic Organic Chemistry of Diketopiperazines

Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.
Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in

Composite Single‐Reference and Explicitly Correlated Multireference Calculations on the Mechanism of Pyrrole Pyrolysis

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

Eyes in the sky: Interactions between AGB winds and the interstellar magnetic field [PDF]

, 2014
We aim to examine the role of the interstellar magnetic field in shaping the extended morphologies of slow dusty winds of Asymptotic Giant-branch (AGB) stars in an effort to pin-point the origin of so-called eye shaped CSE of three carbon-rich AGB stars.

Gasdynamic models of the solar wind/interstellar medium interaction

Geophysical Research Letters, 1994
The interaction between the solar wind and the interstellar medium is modeled self‐consistently using numerical solutions of the time‐dependent gasdynamic equations in spherical and cylindrical coordinates. For the results presented here it is assumed that the solar system moves through the surrounding medium with a supersonic velocity.

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.

Dynamical Effects of Stellar Winds and Associated HII Regions on the Interstellar Medium [PDF]

Symposium - International Astronomical Union, 1987
A dynamical model has been developed, describing the joint evolution of a stellar wind and an associated HII region during the main sequence life time of an OB-star. It is proposed that in case of spherical symmetry all dynamical features are obtained by dividing the flow into spatially homogenous regions separated by discontinuities (shock fronts ...

Deciphering the “Missing Xenon Paradox” in Celestial Bodies: A Multifaceted Perspective Toward Demystifying This Enigma

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 ...
