Strong Bow Shocks: Turbulence and an Exact Self-similar Asymptotic

The Astrophysical Journal
We show that strong bow shocks are turbulent and nonuniversal near the head but asymptote to a universal, steady, self-similar, and analytically solvable flow in the downstream.

Anisotropic Diffusion in Pulsar Halos: Interpreting the Asymmetric Morphology of Geminga and Monogem Halos Measured by HAWC

The Astrophysical Journal
Pulsar halos are produced by electrons and positrons diffusing in the interstellar medium around their parent pulsar wind nebulae. Recent observations by High Altitude Water Cherenkov Observatory and Large High Altitude Air Shower Observatory have ...

Cosmic ray acceleration by stellar wind. Simulation for heliosphere [PDF]

The solar wind deceleration by the interstellar medium may result in the existence of the solar wind terminal shock. In this case a certain fraction of thermal particles after being heated at the shock would obtain enough energy to be injected to the ...

The Role of Pickup Ions in the Interaction of the Solar Wind with the Local Interstellar Medium. II. Effects of Solar Cycle

The Astrophysical Journal
We investigate the role of pickup ions (PUIs) in the interaction of a periodically varying solar wind (SW) with the local interstellar medium (LISM).

12 yr Full Solar Cycle Maps from IBEX-Lo Interstellar Neutral Atom Observations (2009–2020)

The Astrophysical Journal Supplement Series
The Interstellar Boundary Explorer (IBEX) mission investigates the very local interstellar medium (VLISM) and its interaction with our heliosphere, partly by sampling interstellar neutral (ISN) atoms.

Astrospheres and Solar-like Stellar Winds

Living Reviews in Solar Physics, 2004
Stellar analogs for the solar wind have proven to be frustratingly difficult to detect directly. However, these stellar winds can be studied indirectly by observing the interaction regions carved out by the collisions between these winds and the ...

Magnetic Turbulence Intermittency and Compressibility in the Inner Heliosheath and Very Local Interstellar Medium

The Astrophysical Journal Letters
We analyze Voyager 1 magnetic field data through 2024 to study fluctuations from the inner heliosheath into the very local interstellar medium (VLISM).
