Solar Sailing: applications and technology advancement [PDF]

, 2011
Harnessing the power of the Sun to propel a spacecraft may appear somewhat ambitious and the observation that light exerts a force contradicts everyday experiences.

Numerical investigation of hydrodynamic instabilities of the heliopause [PDF]

Journal of Geophysical Research: Space Physics, 1998
The heliopause is the interface between the solar wind plasma and the very local interstellar medium (VLISM) and manifests itself as a tangential discontinuity across which the flow velocity and the plasma density jump (except at the nose). Hydrodynamic instabilities of either the Rayleigh‐Taylor type or the Kelvin‐Helmholtz type will likely develop at

Hybrid Kinetic Modeling of the Magnetosheath Impulsive Plasma Cloud Penetration Through the Magnetopause and Comparison With MMS and Other Spacecraft Observations

Journal of Geophysical Research: Space Physics, Volume 129, Issue 7, July 2024.
Abstract This research examines the plasma processes under penetration of the plasma clouds (plasmoids) across the magnetopause which is modeled as a tangential discontinuity (TD). Cases with the parallel magnetic field in both sides out of the TD are under investigation.

Evidence for an interstellar dust filament in the outer heliosheath

, 2015
A recently discovered filament of polarized starlight that traces a coherent magnetic field is shown to have several properties that are consistent with an origin in the outer heliosheath of the heliosphere: (1) The magnetic field that provides the best ...

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 ...

A Heliopause Spectrum for Electrons

, 2013
We present a heliopause spectrum for galactic electrons over an energy range from 1 MeV to 50 GeV at 122 AU from the Sun. This spectrum can be considered the lowest possible local interstellar spectrum (LIS). This is obtained by using a comprehensive numerical model for solar modulation in comparison with Voyager 1 observations during 2010 and PAMELA ...

The Shape of the Heliosphere Derived from the IBEX Ribbon

The Astrophysical Journal Letters
The shape of the heliosphere remains largely uncertain due to the lack of in situ measurements. However, the energetic neutral atom (ENA) ribbon structure discovered by the Interstellar Boundary EXplorer (IBEX) satellite provides a new perspective.

Time-Dependent Modulation of Cosmic Rays in the Heliosphere

, 2013
The time-dependent modulation of galactic cosmic rays in the heliosphere is studied by computing intensities using a time-dependent modulation model.

A Numerical Model for the Dynamics of Pickup Ions Outside the Heliopause and IBEX “Ribbon” Observation

The Astrophysical Journal
The leading mechanism for the origin of the Interstellar Boundary Explorer (IBEX) “ribbon” of enhanced energetic neutral atoms (ENAs) from the outer heliosphere is the so-called secondary ENA process.

Cosmic ray transport near the heliopause [PDF]

Journal of Physics: Conference Series, 2015
In this paper we summarize our modelling efforts for cosmic rays near the heliopause, and discuss whether galactic cosmic ray modulation beyond the heliopause is possible and present an explanation for the anisotropic nature of the observed cosmic ray intensities in the very local interstellar medium.
