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 ...

Nearby Supernova and Cloud Crossing Effects on the Orbits of Small Bodies in the Solar System

The Astrophysical Journal Letters
Supernova (SN) blasts envelop many surrounding stellar systems, transferring kinetic energy to small bodies in the systems. Geologic evidence from ^60 Fe points to recent nearby SN activity within the past several Myr.

Molecular cloud structure in the star-forming region W43

, 2013
In the struggle toward an understanding of the process of star formation it is one of the most important tasks to study the initial properties of the cold and dense interstellar medium. Stars are known to form in dense molecular clouds, but it is not yet

Assessment of detectability of neutral interstellar deuterium by IBEX observations [PDF]

, 2013
Context. The abundance of deuterium in the interstellar gas in front of the Sun gives insight into the processes of filtration of neutral interstellar species through the heliospheric interface and potentially into the chemical evolution of the Galactic ...

On the Genetic Relation Between Interstellar Clouds and Dust Clouds [PDF]

Symposium - International Astronomical Union, 1973
We propose that many of the denser dust clouds represent transient stages between the initiation of gravitational collapse of ordinary interstellar clouds by passage through a spiral galactic shock and the appearance of a stellar association. The interstellar gas is not processed at too rapid a rate (1) because the time spent between galactic shocks is

Shock waves in Interstellar Cloud-Cloud and Wind-Cloud Collisions

The interstellar medium (ISM) is a key ingredient of galaxies and their evolution, consisting of multiphase, turbulent dust and gas. Some of the star-forming regions in our Galaxy originate from cloud-cloud and wind-cloud collisions, which generate shock

Implications for the formation of Oort cloud-like structures and interstellar comets in dense environments

Astronomy & Astrophysics
Most stars form in dense stellar environments, where frequent close encounters can strongly perturb and reshape the early architecture of planetary systems.
