The Astrophysical JournalThe Voyager spacecraft (V1 and V2) provide unique in situ measurements of perturbations propagating beyond the heliopause through the very local interstellar medium (VLISM), including the shocks and pressure fronts whose origin is debated. In particular,

A numerical simulation of cosmic-ray modulation near the heliopause [PDF]
, 2015 Based on a hybrid galactic cosmic-ray transport model, which incorporated MHD global heliospheric data into Parker’s cosmic-ray transport equation, we studied the behavior of the transport of galactic cosmic rays and the corresponding gradients in ...

Implications of the Voyager 1 and 2 Magnetic Field Directions on the Energetic Neutral Atom Ribbon
The Astrophysical JournalThe interstellar magnetic field direction can be inferred from the position of the energetic neutral atom (ENA) Ribbon observed by Interstellar Boundary EXplorer (IBEX) and Voyager 1 and 2 in situ measurements.

ARE COSMIC RAYS MODULATED BEYOND THE HELIOPAUSE?
The Astrophysical Journal, 2014 We discuss the possible spatial variation of Galactic and anomalous cosmic rays (GCRs and ACRs) at and beyond the heliopause (HP). Remaining within the framework of the Parker transport equation and assuming incompressible plasma in the heliosheath, we consider highly idealized simple-flow models and compare our GCR results with recent publications of ...

Solar sail mission applications and future advancement [PDF]
, 2010 Solar sailing has long been envisaged as an enabling technology. The promise of open-ended missions allows consideration of radically new trajectories and the delivery of spacecraft to previously unreachable or unsustainable observation outposts.

The Magnetic Hump, Heliopause and the VLISM [PDF]
The magnetic hump was observed from 2020.4 to ~2022 by Burlaga et al. who offered the hypothesis that it originated at the Sun during the declining phase of the solar cycle.

New families of non-Keplerian orbits : Solar sail motion over cylinders and spheres [PDF]
, 2014 This paper presents new families of Sun-centered non-Keplerian orbits (NKOs), where the motion of a high-performance solar sail is confined to either a cylindrical or spherical surface.

Simulating a Steady-state Heliosphere
The Astrophysical Journal Supplement SeriesEver since the discovery of the solar wind, it has been understood that our solar system resides within a bubble of solar wind plasma that originates from the Sun.

The Solar Magnetic Hump, Heliopause, and the Very Local Interstellar Medium
The Astrophysical Journal LettersThe magnetic hump was observed from 2020.4 to ∼2022 by Burlaga et al. who offered the hypothesis that it originated at the Sun during the declining phase of the solar cycle.
