Suprathermal particle addition to solar wind pressure: possible influence on magnetospheric transmissivity of low energy cosmic rays?

open access: yes, 2013
Energetic (suprathermal) solar particles, accelerated in the interplanetary medium, contribute to the solar wind pressure, in particular during high solar activity periods.

Helmet and active streamers from radio observations [PDF]

open access: yes
Large coronal regions disconnected from any calcium plages and identified by their thermal emission at 169 mHz play a basic role in the sector structure of the interplanetary medium.

Microstructure of the Interplanetary Medium [PDF]

open access: yes
High time resolution measurements of the interplanetary magnetic field and plasma reveal a complex microstructure which includes hydromagnetic wave and discontinuities.

Solar-terrestrial response to large extension or long-duration solar gamma ray events [PDF]

open access: yesGeofísica Internacional, 2000
Gamma ray lines (GRL) from the large event of 29 September 1989 were observed from a site about 25 degrees from the flare site. In June 1991, at least three long-duration GRL events were observed by several spacecraft.

Observational signatures of planetary tidal disruption events around solar-mass stars

open access: yesAstronomy & Astrophysics
Context. The tidal disruption of planets by their host stars represents a growing area of interest in transient astronomy, offering insights into the final stages of planetary system evolution and the scattering of planets in gas-poor environments. Aims.

Damping of high frequency waves in the solar wind [PDF]

open access: yes
Cyclotron damping by suprathermal fluxes of protons and electrons in the interplanetary medium will greatly attenuate high frequency Alfven waves and whistler waves within distances 1 AU of the sun.

Anomalous cosmic rays within the inner heliosphere: Observations of helium by the High Energy Telescope on board Solar Orbiter

open access: yesAstronomy & Astrophysics
Context. The radial gradients of cosmic rays are key parameters in studies of the transport of particles in space. Solar Orbiter, launched on 2020 February 10, approaches the Sun approximately every half-a-year, with its closest perihelion distance of 0 ...

Identification and prediction of prolonged intervals of geomagnetic calm [PDF]

open access: yesGeofísica Internacional, 2002
From the daily index Ap of geomagnetic activity, sequences of consecutive occurrence of Ap≤4 for four days and Ap≤7 for 8 days are identified in the period 1963-1998.

Interplanetary stream interfaces [PDF]

open access: yes
At l AU there is a distinct boundary (the stream interface) at the leading edge of a stream in the solar wind, characterized by an abrupt drop in density, a similar increase in temperature and a small increase in speed.

Preconditioning of the Interplanetary Medium Due To Isolated ICMEs

open access: yesJournal of Geophysical Research: Space Physics
AbstractWe perform a systematic study of the preconditioning of the interplanetary (IP) medium due to isolated IP coronal mass ejections (ICMEs). Preconditioning is highly relevant when ICMEs, ejected in close succession and direction, modify the IP medium to allow subsequent ICMEs to propagate more freely, decelerate less, and retain higher kinetic ...
