The Heliosphere Is Not Round

open access: yesThe Astrophysical Journal, 2018
Abstract Observations from the Ion and Neutral Camera (INCA) on the Cassini mission of energetic neutral atoms (ENAs) at ∼10 keV and ∼45 keV showed significant correlated time variations over relatively fast 2–3 yr timescales. These observed ENA variations have been interpreted as indicating limited scale lengths of ∼80–120 au along the ...

A predicted small and round heliosphere [PDF]

open access: yes, 2018
The shape of the solar wind bubble within the interstellar medium, the so-called heliosphere, has been explored over six decades(1-7). As the Sun moves through the surrounding partially-ionized medium, neutral hydrogen atoms penetrate the heliosphere ...

Solar influences in the heliosphere: understanding coronal mass ejections and their associated magnetic clouds

open access: yes, 2011
Coronal mass ejections (CMEs) are large-scale explosions on the Sun that expel plasma and magnetic field into the heliosphere. The interplanetary counterparts of CMEs, termed interplanetary CMEs (ICMEs), are often directly observed by spacecraft ...

Long-term solar activity and its implications to the heliosphere, geomagnetic activity, and the Earth’s climate

open access: yesJournal of Space Weather and Space Climate, 2013
The Sun’s long-term magnetic variability is the primary driver of space climate. This variability is manifested not only in the long-observed and dramatic change of magnetic fields on the solar surface, but also in the changing solar radiative output ...

Cosmic rays in the heliosphere

open access: yes, 1987
The different types of cosmic ray particles and their role in the heliosphere are briefly described. The rates of various energetic particles were examined as a function of time and used to derive various differential energy gradients.

Fifty years of studying the GCR intensity during inversion of the heliospheric magnetic fields. II. HMF inversion on the inner heliospheric boundary

open access: yesSolar-Terrestrial Physics
Phenomena in the outer layer of the solar atmosphere, the heliosphere, including the supersonic solar wind, the heliospheric magnetic field (HMF) carried by it, and cosmic rays propagating in the heliosphere are important for many processes occurring in ...

Asymmetry of the heliosphere

open access: yesGeophysical Research Letters, 1987
The outflowing solar wind interacts with the local interstellar medium to form the heliospheric cavity within which the solar wind is supersonic. Because the interstellar medium is moving with respect to the Sun, and because the solar wind has a latitude dependence, the heliosphere is asymmetric. The flow of the interstellar medium past the heliosphere

The Heliosphere Through the Solar Activity Cycle

open access: yes, 2006
Understanding how the Sun changes though its 11-year sunspot cycle and how these changes affect the vast space around the Sun the heliosphere has been one of the principal objectives of space research since the advent of the space age. This book presents

Globally distributed energetic neutral atom maps for the "croissant" heliosphere [PDF]

open access: yes, 2018
A recent study by Opher et al. suggested the heliosphere has a "croissant" shape, where the heliosheath plasma is confined by the toroidal solar magnetic field.

Simulations of Coronal Mass Ejection Injection into the Inner Heliosphere with Displacement of the Heliospheric Magnetic Field

open access: yesThe Astrophysical Journal
Magnetohydrodynamic (MHD) simulations are a useful tool for understanding the propagation of coronal mass ejections (CMEs) in the inner heliosphere and their interaction with the background solar wind.
