On the Spatial Distribution of 13CO Structures within 12CO Molecular Clouds

The Astrophysical Journal, 2023
We look into the 2851 ^12 CO molecular clouds harboring ^13 CO structures to reveal the distribution of the projected angular separations and radial velocity separations between their internal ^13 CO structures.

Atmospheric and Deposition Responses of 10Be to Volcanic Eruptions Inferred From the Aerosol‐Climate Model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract 10Be deposition in ice cores is widely used for solar reconstructions, but its interpretation is complicated by volcanic influences. Using the state‐of‐the‐art aerosol‐climate model ECHAM6.3‐HAM2.3‐SALSA2.0: 10Be, we assess the impacts of three major volcanic eruptions: Agung (1963), El Chichón (1982) and Pinatubo (1991). All eruptions enhance

Turbulent Driving Scales in Molecular Clouds

, 2009
Supersonic turbulence in molecular clouds is a dominant agent that strongly affects the clouds' evolution and star formation activity. Turbulence may be initiated and maintained by a number of processes, acting at a wide range of physical scales.

Cluster Models for Next‐Generation, Machine‐Learning‐Based Energy Functions for Molecular Simulations

Small Structures, Volume 7, Issue 2, February 2026.
This work describes how to conceive validated mixed machine learned/empirical energy functions based on finite‐sized molecular clusters for condensed phase simulations. Energy functions for pure and heterogeneous systems are one of the backbones for molecular simulation of condensed phase systems.

Tracing the Layers of Photodissociated Gas in the Trifid Nebula

The Astrophysical Journal
Photodissociated gas bears the signature of the dynamical evolution of the ambient interstellar medium impacted by the mechanical and radiative feedback from an expanding H ii region.

DESTRUCTION OF THE INTERSTELLAR CLOUDS BY THESHOCK WAVES

Odessa Astronomical Publications, 2008
We study the influence of the interstellar cloud structure irregularity on the dynamics of its destruction by a supernova shock wave. It is shown that irregular clouds are destroyed twice quickly as the spherical ones.

Sampling the volcanic plumes at Io: Impact speeds and shock conditions

Meteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

What Rogue Hydrogen Clouds Tell Us about Galactic Magnetic Fields

The Astrophysical Journal
Observations of the Milky Way and external galaxies support the idea that large-scale magnetic fields are concentrated in galactic disks, with halo magnetic fields at least an order of magnitude weaker.

Clouds, Clumps, Cores & Comets - a Cosmic Chemical Connection?

, 2008
We discuss the connection between the chemistry of dense interstellar clouds and those characteristics of cometary matter that could be remnants of it. The chemical evolution observed to occur in molecular clouds is summarized and a model for dense core ...
