Heating the outer heliosphere by pickup protons [PDF]

open access: yes, 2004
There is a growing body of literature that demonstrates the ability of a turbulent cascade within the solar wind to heat the thermal protons. Several sources of energy are required to accomplish the observed heating.

Interplanetary Dust [PDF]

open access: yes, 2001
This is a handbook on the physics of interplanetary dust, a topic of interest not only to astronomers and space scientists but also to engineers. The following topics are covered in the book: historical perspectives; cometary dust; near-Earth environment;

Predictions of the arrival time of Coronal Mass Ejections at 1AU: an analysis of the causes of errors [PDF]

open access: yesAnnales Geophysicae, 2004
Three existing models of Interplanetary Coronal Mass Ejection (ICME) transit between the Sun and the Earth are compared to coronagraph and in situ observations: all three models are found to perform with a similar level of accuracy (i.e.

Open flux estimates in Saturn's magnetosphere during the January 2004 Cassini-HST campaign, and implications for reconnection rates [PDF]

open access: yes, 2005
peer reviewedDuring 8-30 January 2004, a sequence of 68 UV images of Saturn's southern aurora was obtained by the Hubble Space Telescope (HST), coordinated for the first time with measurements of the upstream interplanetary conditions made by the Cassini

In situ local shock speed and transit shock speed [PDF]

open access: yesAnnales Geophysicae, 1998
A useful index for estimating the transit speeds was derived by analyzing interplanetary shock observations. This index is the ratio of the in situ local shock speed and the transit speed; it is 0.6–0.9 for most observed shocks.

Cassini encounters with hot flow anomaly-like phenomena at Saturn's bow shock [PDF]

open access: yes, 2008
The first observations of the kronian equivalent of hot flow anomalies (HFAs) are presented. Using magnetic field and plasma data we discuss two events that were observed upstream of Saturn's bow shock during the first two orbits of the Cassini ...

What causes the variations of the peak intensity of CIR accelerated energetic ion fluxes? [PDF]

open access: yesAnnales Geophysicae, 1998
The variation of the peak intensity of energetic ions accelerated at CIR related shocks in the interplanetary medium as observed by instruments on board of ULYSSES during its pass towards the south polar region and from the north polar region back to ...

The Physical Nature of Interplanetary Dust as Inferred by Particles Collected at 35 km [PDF]

open access: yesInternational Astronomical Union Colloquium, 1971
Particles were collected at an altitude of 35 km by two flights of a volume-sampling micrometeorite collector. The collection scheme is very sensitive and is capable of collecting a significant number of particles. Many of the particles collected have chemical compositions similar to solar or to iron meteorites.

Signature of Saturn's auroral cusp: Simultaneous Hubble Space Telescope FUV observations and upstream solar wind monitoring [PDF]

open access: yes, 2005
peer reviewedModel simulations by Bunce et al. (2005a) have shown that direct precipitation of electrons in Saturn's dayside cusp regions is not capable of producing significant FUV aurora.

Magnetic topology of coronal mass ejection events out of the ecliptic: Ulysses/HI-SCALE energetic particle observations [PDF]

open access: yesAnnales Geophysicae, 2003
Solar energetic particle fluxes (Ee > 38 keV) observed by the ULYSSES/HI-SCALE experiment are utilized as diagnostic tracers of the large-scale structure and topology of the Interplanetary Magnetic Field (IMF) embedded within two well ...
