Scattering of Superthermal Ions at Shocks: Dependence on Energy
The Astrophysical Journal, 2023 Diffusive shock acceleration requires the production of backstreaming superthermal ions (injection) as a first step. Such ions can be generated in the process of scattering of ions in the superthermal tail off the shock front. Knowledge of the scattering

First Observations of Irregular Surface of Interplanetary Shocks at Ion Scales by Cluster [PDF]
Astrophysical Journal, 2019 We present the first observational evidence of the irregular surface of interplanetary (IP) shocks by using multispacecraft observations of the Cluster mission.

Interaction of a strong interplanetary shock with the termination shock [PDF]
Journal of Geophysical Research: Space Physics, 1999 The 1991 global merged interaction region (GMIR) shock is a strong forward shock observed from Voyager 2 on day 146 of 1991 at 34.6 AU. As the GMIR shock propagated out‐ward in the distant heliosphere, it eventually encounters the termination shock. We study the interaction of the GMIR shock with the termination shock taking into account the influence ...

Transit of the Interplanetary Shocks Associated with Type II Radio Bursts Within 1AU [PDF]
Journal of Astronomy and Space Sciences, 2007 Among the interplanetary shock (IP shock)s observed by ACE spacecraft at 1AU during 1997 to 2000, we have selected 31 IP shocks which had triggered the interplanetary type II radio bursts detected by the WIND spacecraft while those shocks were leaving ...

Shock Heating of Incident Thermal and Superthermal Populations of Different Ion Species
The Astrophysical Journal, 2023 Using ion tracing in a model shock front we study heating of thermal (Maxwellian) and superthermal (Vasyliunas–Siscoe) populations of protons, singly charged helium, and alpha particles. It is found that heating of thermal and superthermal populations is

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 ...

Storm Sudden Commencements Without Interplanetary Shocks [PDF]
Journal of Astronomy and Space Sciences, 2015 Storm sudden commencements (SSCs) occur due to a rapid compression of the Earth's magnetic field. This is generally believed to be caused by interplanetary (IP) shocks, but with exceptions. In this paper we explore possible causes of SSCs other than IP
