The combined influence of stellar energetic particles and galactic cosmic rays (GCRs) on the radiation environment, and hence potential habitability, of Earth-like exoplanets is relatively unknown.

Comparative collisionless shocks beyond Earth
Collisionless shock waves are an ubiquitous phenomena occurring upstream of planetary magnetospheres, cometary bodies, coronal mass ejections (CMEs), and astrospheres.

Voyager VLISM Electron Density Dataset
This paper is a companion to an electron density dataset submitted to both the Planetary Data System and the Space Physics Data Facility for measurements by the Voyager Plasma Wave Science (PWS) instrument in the very local interstellar medium.

Several studies of Galactic cosmic-ray (GCR) modulation within the astrospheres of stars deemed to be proxies for the young Sun have concluded that the intensities of these particles would, at early stages of the Sun’s evolution, be negligible at 1 au ...

The Passage of the Solar System through the Edge of the Local Bubble
The Sun moves through the interstellar medium (ISM) at a velocity of ∼19 pc Myr ^−1 , making the conditions outside the solar system vary with time over millions of years.

New Mass-Loss Measurements from Astrospheric Lyα Absorption [PDF]
Measurements of stellar mass-loss rates are used to assess how wind strength varies with coronal activity and age for solar-like stars. Mass loss generally increases with activity, but we find evidence that winds suddenly weaken at a certain activity threshold.

The Global Structure of the Heliosphere
As the Sun moves through the local interstellar medium (LISM), it emits charged particles, creating the heliosphere occupied by the plasma of solar origin.

This paper examines the geometry of interstellar magnetic field lines close to the boundary of the heliosphere in the direction of the unperturbed local interstellar magnetic field, where the field lines are spread apart by the heliopause (HP).

A Search for Lyα Emission from the Astrosphere of 40 Eridani A
We report the results of Hubble Space Telescope (HST) observations of the nearby (d = 5.0 pc) K1 V star 40 Eri A, which we use to search for scattered Lyα emission surrounding the star indicative of the interaction between the stellar wind and the interstellar medium (ISM).

Signatures of Reconnection and a Split Heliospheric Tail in High-energy Energetic Neutral Atoms
The shape of the heliosphere, regarded as comet-like since the 1960s, has recently been the subject of intense debate in the last decade. There is disagreement as to whether the heliospheric tail extends to ∼10,000 au in a comet-like shape or if it is ...
