Helmet and active streamers from radio observations [PDF]
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.

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

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