Local interstellar cloud grains outside the heliopause [PDF]

, 2003
The dynamics of small (~0.01 μm) interstellar grains in the heliospheric transition region is studied using numerical simulations. The velocity distributions of the grains at the boundary of the heliosphere are found to depend sensitively on the global ...

Complementary interstellar detections from the heliotail

Frontiers in Astronomy and Space Sciences
The heliosphere is a protective shield around the solar system created by the Sun’s interaction with the local interstellar medium (LISM) through the solar wind, transients, and interplanetary magnetic field.

Evidence of a Thick Heliopause Boundary Layer Resulting from Active Magnetic Reconnection with the Interstellar Medium

The Astrophysical Journal
Voyager 1 and 2 data from the vicinity of the heliopause and very local interstellar medium are reexamined to better understand the confounding lack of rotation in the magnetic field ( B -field) across the heliopause observed by both Voyagers, despite ...

Simulating observable structures due to a perturbed interstellar medium in front of astrospheric bow shocks in 3D MHD [PDF]

, 2021
Context. While the shapes of many observed bow shocks can be reproduced by simple astrosphere models, more elaborate approaches have recently been used to explain differing observable structures. Aims. By placing perturbations of an otherwise homogeneous

On the Comprehensive 3D Modeling of the Radiation Environment of Proxima Centauri b: A New Constraint on Habitability?

The Astrophysical Journal
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.

Heliophysics: active stars, their astrospheres, and impacts on planetary environments [PDF]

, 2016
Heliophysics is a fast-developing scientific discipline that integrates studies of the Sun's variability, the surrounding heliosphere, and the environment and climate of planets. This volume, the fourth in the Heliophysics collection, explores what makes

Voyager VLISM Electron Density Dataset

The Astrophysical Journal Supplement Series
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.

New Mass-Loss Measurements from Astrospheric Lyα Absorption [PDF]

The Astrophysical Journal, 2005
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 Passage of the Solar System through the Edge of the Local Bubble

The Astrophysical Journal
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.

Magnetic Trapping of Galactic Cosmic Rays in the Outer Heliosheath and Their Preferential Entry into the Heliosphere

The Astrophysical Journal
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).
