Astro2020 Science White Paper: Synoptic Studies of the Sun as a Key to Understanding Stellar Astrospheres

open access: yes, 2019
Ground-based solar observations provide key contextual data (i.e., the 'big picture') to produce a complete description of the only astrosphere we can study in situ: our Sun's heliosphere.

The density distribution and 58.4 nm radiation intensity of interstellar helium in the heliosphere: a model simulation

open access: yesEarth and Planetary Physics
Research on the interstellar medium and its interaction with the solar system constitutes a significant topic in planetary physics. As the Sun traverses the local interstellar cloud, interstellar neutrals penetrate the heliosphere, forming the ...

Astrospheres and Solar-like Stellar Winds

open access: yesLiving Reviews in Solar Physics, 2004
Stellar analogs for the solar wind have proven to be frustratingly difficult to detect directly. However, these stellar winds can be studied indirectly by observing the interaction regions carved out by the collisions between these winds and the ...

Consequences of Hot Electrons for the Structure of the Outer Heliosphere

open access: yesThe Astrophysical Journal
The temperature of electrons is largely unknown in the outer heliosphere because there is a gap in Voyager measurements from ∼3 eV to 22 keV. Most models assume that the electrons have the same temperature as the bulk cold thermal solar wind (10 ^4 K ...

Production and Loss Processes of Hydrogen Energetic Neutral Atoms in the Heliosphere from 5 eV–500 keV

open access: yesThe Astrophysical Journal Supplement Series
Energetic neutral atom (ENA) observations provide valuable insights into the plasma conditions in the heliosphere and the surrounding interstellar medium.

THE SUN AND THE HELIOSPHERE IN FEBRUARY-MARCH, 1986

open access: yesTHE SUN AND THE HELIOSPHERE IN FEBRUARY-MARCH, 1986
Conditions of the sun and the heliosphere are studied in relation to the intense disturbances of the earth's and cometary magnetospheres in February and March, 1986. In this sunspot minimum phase, the sun had essentially the southward axial dipole which was to produce a weak northward IMF. However, one bipolar magnetic region in the northern hemisphere
