The Sun and the Heliosphere

2000
The advent of space age with its new capabilities of satellites and space probes to fly sophisticated instruments in space for a long period of time for studying the Sun and the solar system, opened up many new windows of knowledge on solar physics and space astrophysics.

Solar orbiter, a high-resolution mission to the sun and inner heliosphere

Advances in Space Research, 2002
Abstract The scientific rationale of the Solar Orbiter is to provide, at high spatial (35 km pixel size) and temporal resolution, observations of the solar atmosphere and unexplored inner heliosphere. Novel observations will be made in the almost heliosynchronous segments of the orbits at heliocentric distances near 45 R⊙ and out of the ecliptic ...

Sun and heliosphere in ESA's scientific programme

Physics and Chemistry of the Earth, 1997
Abstract Two of the five missions in ESA's Scientific Programme that are currently operated in orbit are devoted to solar and heliospheric science: ULYSSES and SOHO. ULYSSES explores the heliosphere in a heliocentric out-of-ecliptic orbit - predominantly through in-situ sensing of its local plasma environment and by solar-wind and cosmic-ray ...

Heliospheric Physics: Linking the Sun to the Magnetosphere

Space Science Reviews, 2006
Research into the heliospheric structure and its relation to the solar boundary is at an impasse. After successful predictions by Parker about the zeroth-order behavior of the heliospheric magnetic field and the solar wind, the heliospheric community struggles to make substantive progress toward a predictive model describing the connections between the

A New View of the Coupling of the Sun and the Heliosphere

Annual Review of Astronomy and Astrophysics, 2007
The structure of the global heliospheric field reflects the physical properties of the low corona. The implied connections between solar and heliospheric evolution have been analyzed by a powerful multisatellite solar and heliospheric observatory that includes the Ulysses and the Solar and Heliospheric Observatory (SOHO) spacecraft.

Reconnection Process in the Sun and Heliosphere

2010
Solar flare, coronal mass ejection and many other interesting plasma and magnetic field structures in the heliosphere are believed to be generated by a powerful plasma process widely known as reconnection of magnetic field lines. The basic understanding of this reconnection process is described by considering a simple model suggested by Dungey that ...

Solar Orbiter: Linking the Sun and Inner Heliosphere

2010
Solar Orbiter, a candidate mission in ESA’s Cosmic Vision programme, is designed to study the Sun and inner heliosphere in greater detail than ever before. At the closest point on its heliocentric orbit, the Solar Orbiter spacecraft will be about 0.23 AU from the Sun, closer than any other satellite to date.

Sun and Solar Wind: Plasmas in the Heliosphere

1998
Plasmas in interplanetary space originate from the Sun, as do most of the disturbances and waves embedded in them. The solar atmosphere, the corona, extends as solar wind far beyond the orbit of the outermost planet, Pluto, filling a cavity in the interstellar medium called the heliosphere.

Acceleration of energetic particles on the Sun, in the Heliosphere, and in the Galaxy

AIP Conference Proceedings, 2000
This review describes the energetic particle populations observed in the heliosphere including gradual and impulsive solar energetic particle (SEP) events, interplanetary energetic particle enhancements, the anomalous cosmic ray (ACR) component, and galactic cosmic rays (GCRs).
