Connecting the Sun to the heliosphere [PDF]

Eos, Transactions American Geophysical Union, 2007
To better understand the processes that connect the Earth environment to the Sun, NASA's Living With a Star program must address questions that cut across traditional science disciplines. To meet this challenge, the Targeted Research and Technology component of Living With a Star has developed an innovative strategy to focus research on the most ...

The Sun and heliosphere explorer – the Interhelioprobe mission

Geomagnetism and Aeronomy, 2016
The Interhelioprobe mission aims to investigate the inner heliosphere and the Sun from close distances (up to 0.3 AU) and from out of the ecliptic plane (up to 30°). In this paper we present the relevance of the mission and its main scientific objectives, describe the scientific payload, ballistic scenario and orbits of the spacecraft. Possibilities of

DIVISION II: SUN and HELIOSPHERE [PDF]

Proceedings of the International Astronomical Union, 2011
The solar activity cycle entered a prolonged quiet phase that started in 2008 and ended in 2010. This minimum lasted for a year longer than expected and all activity proxies, as measured from Earth and from Space, reached minimum values never observed before (de Toma, 2012).

Rotational Quasi-Periodicities and the Sun – Heliosphere Connection [PDF]

Solar Physics, 2008
Mutual quasi-periodicities near the solar-rotation period appear in time series based on the Earth's magnetic field, the interplanetary magnetic field, and signed solar-magnetic fields. Dominant among these is one at 27.03 +/- 0.02 days that has been highlighted by Neugebauer, et al. 2000, J. Geophys. Res., 105, 2315.

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

Solar-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 ...

Solar wind stream interaction regions throughout the heliosphere

Living Reviews in Solar Physics, 2018
This paper focuses on the interactions between the fast solar wind from coronal holes and the intervening slower solar wind, leading to the creation of stream interaction regions that corotate with the Sun and may persist for many solar rotations. Stream
