Abundances and charge states of particles in the solar wind
- P. Bochsler
- Physics
- 1 May 2000
The Sun is the only star from which matter can be collected in order to investigate its elemental and isotopic composition. Solar elemental abundances pro- vide the most important benchmark for the… Expand
Global Observations of the Interstellar Interaction from the Interstellar Boundary Explorer (IBEX)
- D. McComas, F. Allegrini, +33 authors G. Zank
- Physics, Medicine
- Science
- 13 November 2009
What's Happening in the Heliosphere The influence of the Sun is felt well beyond the orbits of the planets. The solar wind is a stream of charged particles emanating from the Sun that carves a bubble… Expand
Solar Wind Neon from Genesis: Implications for the Lunar Noble Gas Record
- A. Grimberg, H. Baur, +6 authors R. Wieler
- Chemistry, Medicine
- Science
- 17 November 2006
Lunar soils have been thought to contain two solar noble gas components with distinct isotopic composition. One has been identified as implanted solar wind, the other as higher-energy solar… Expand
Neon-20, oxygen-16, and helium-4 densities, temperatures, and suprathermal tails in the solar wind determined with WIND/MASS
- M. Collier, D. Hamilton, G. Gloeckler, P. Bochsler, R. Sheldon
- Physics
- 15 May 1996
Measurements from the MASS instrument on the WIND spacecraft from late Dec. 94 through Aug. 95 are reported for 20Ne, 16O, and 4He. The average 4He/20Ne density ratio is 566±87 with considerable… Expand
Solar wind measurements with SOHO: The CELIAS/MTOF proton monitor
- F. Ipavich, A. Galvin, +26 authors P. Wurz
- Physics
- 1 August 1998
The proton monitor, a small subsensor in the Charge, Element, and Isotope Analysis System/Mass Time-of-Flight (CELIAS/MTOF) experiment on the SOHO spacecraft, was designed to assist in the… Expand
The helium isotopic ratio in the solar wind and ion fractionation in the corona by inefficient Coulomb drag
- R. Bodmer, P. Bochsler
- Physics
- 1 September 1998
Using data obtained between 1991 and 1996 with the SWICS instrument (Solar Wind Ion Composition Spectrome- ter) aboard the Ulysses spacecraft, a long time average of the ( 4 He= 3 He) isotopic ratio… Expand
Minor ions in the solar wind
- P. Bochsler
- Physics
- 15 January 2007
Ions heavier than 4He are treated as “minors” in the solar wind. This is justified for many applications since minor ions have no significant influence on the dynamics of the interplanetary plasma.… Expand
Solar Parameters for Modeling the Interplanetary Background
- M. Bzowski, J. M. Sokól, +6 authors D. McComas
- Physics
- 13 December 2011
The goal of the working group on cross-calibration of past and present ultraviolet (UV) datasets of the International Space Science Institute (ISSI) in Bern, Switzerland was to establish a… Expand
Solar wind helium isotopic composition from SWICS/ULYSSES
- R. Bodmer, P. Bochsler, J. Geiss, R. V. Steiger, G. Gloeckler
- Physics
- 1 April 1995
This is the first study of the isotopic composition of solar wind helium with the SWICS time-of flight mass spectrometer. Although the design of SWICS is not optimized to measure3He abundances… Expand
MEASUREMENT OF 3 He/ 4 He IN THE LOCAL INTERSTELLAR MEDIUM: THE COLLISA EXPERIMENT ON MIR
- E. Salerno, F. Bühler, +5 authors N. Eismont
- Physics
- 10 March 2003
An accurate measurement of the noble gas isotopic composition in the local interstellar medium (LISM) provides a constraint of primary importance for modeling Galactic evolution and, in some cases,… Expand
