Shock metamorphic effects in Itokawa phosphates: A comparison with megaregolith‐derived meteorites

Meteoritics &Planetary Science, EarlyView.
Abstract Returned regolith samples from the asteroid Itokawa provide a unique opportunity to compare shock metamorphic effects in unconsolidated regolith materials with those preserved in lithified meteorites, that is, megaregolith. We analyzed four Itokawa particles (Ueda—RA‐QD02‐0519, Narahara—RA‐QD02‐0573, Domon—RA‐QD02‐0588, Ishiuchi—RX‐MD03‐0212 ...

The Speed of Interplanetary Shocks Through the Magnetosheath: A Toy Model

Geophysical Research Letters
Before interacting with the magnetosphere, an interplanetary shock travels through the magnetosheath where its speed and shape are modified. Previous studies have reported widely different answers to the question of the speed of an interplanetary shock ...

Turbulence development behind the bow shock during disturbed and undisturbed solar wind

Solar-Terrestrial Physics
Magnetosheath is a transition layer between the solar wind and the magnetosphere and may contribute to the geoeffectiveness of various large-scale interplanetary phenomena.

Irregular Proton Injection to High Energies at Interplanetary Shocks

The Astrophysical Journal Letters, 2023
How thermal particles are accelerated to suprathermal energies is an unsolved issue, crucial for many astrophysical systems. We report novel observations of irregular, dispersive enhancements of the suprathermal particle population upstream of a high ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Acceleration of Solar Wind Ions by Nearby Interplanetary Shocks: Comparison of Monte Carlo Simulations with Ulysses Observations [PDF]

, 1996
The most stringent test of theoretical models of the first-order Fermi mechanism at collisionless astrophysical shocks is a comparison of the theoretical predictions with observational data on particle populations.

Surface‐Driven Protocell Formation in Geologically Relevant Early Earth Environment

ChemSystemsChem, Volume 8, Issue 2, March 2026.
Illustration of a prebiotic early‐Earth environment showing cell‐like protocells (blue spheres) and other complex organic molecules (pink and green spheres) distributed across terrestrial surfaces and within subsurface niches. Volcanic landscapes and mineral‐rich substrates provide diverse geochemical settings for the assembly and evolution of ...

Mercury’s Bow Shock and Magnetopause Variations According to MESSENGER Data

Universe
Using data from the MESSENGER spacecraft magnetometer that describes the magnetopause and the bow shock crossing points of the Mercury’s magnetosphere, we have calculated the parameters of the paraboloids of revolution approximating the obtained points ...

Magnetohydrodynamic Simulation of the Interaction between Interplanetary Strong Shock and Magnetic Cloud and its Consequent Geoeffectiveness 2: Oblique Collision

, 2009
Numerical studies of the interplanetary "shock overtaking magnetic cloud (MC)" event are continued by a 2.5 dimensional magnetohydrodynamic (MHD) model in heliospheric meridional plane.
