An Overview of Solar Orbiter Observations of Interplanetary Shocks in Solar Cycle 25
D. Trotta, A. Dimmock, H. Hietala +17
Interplanetary shocks are fundamental constituents of the heliosphere, where they form as a result of solar activity. We use previously unavailable measurements of interplanetary s…
Observation of a Fully-formed Forward--Reverse Shock Pair Due to the Interaction Between Two Coronal Mass Ejections at 0.5 au
D. Trotta, A. Dimmock, X. Blanco-Cano +17
We report direct observations of a fast magnetosonic forward--reverse shock pair observed by Solar Orbiter on March 8, 2022 at the short heliocentric distance of 0.5 au. The struct…
Ion Dynamics Across a Low Mach Number Bow Shock
D. B. Graham, Yu. V. Khotyaintsev, A. P. Dimmock +4
A thorough understanding of collisionless shocks requires knowledge of how different ion species are accelerated across the shock. We investigate a bow shock crossing using the Mag…
Irregular proton injection to high energies at interplanetary shocks
Domenico Trotta, Timothy S. Horbury, David Lario +8
How thermal particles are accelerated to suprathermal energies is an unsolved issue, crucial for many astrophysical systems. We report novel observations of irregular, dispersive e…
