Heliospheric and Interstellar Phenomena Deduced from Pickup Ion Observations
Pickup ions, created by ionization of slow moving atoms and molecules well inside the heliosphere, provide us with a new tool to probe remote regions in and beyond the heliosphere and to study injection and acceleration processes in the solar wind. Comprehensive and continuous measurements of H, He, C, N, O, Ne and other pickup ions, especially with the Solar Wind Ion Composition Spectrometer (...
متن کاملDensity of neutral interstellar hydrogen at the termination shock from Ulysses pickup ion observations
Aims. By reevaluating a 13-month stretch of Ulysses SWICS H pickup ion measurements near 5 AU close to the ecliptic right after the previous solar minimum, this paper presents a determination of the neutral interstellar H density at the solar wind termination shock and implications for the density and ionization degree of hydrogen in the LIC. Methods. The density of neutral interstellar hydroge...
متن کاملObservations of interstellar helium pickup ions in the inner heliosphere
[1] During the MESSENGER spacecraft’s interplanetary trajectory to Mercury, the Fast Imaging Plasma Spectrometer (FIPS) measured the first helium pickup ion distributions at a heliocentric distance (R) ranging between 0.3 and 0.7 AU. From several transits of MESSENGER through the interstellar helium gravitational focusing cone, we map the cone structure in the ecliptic at R = 0.3 AU and compare...
متن کاملA Discussion on Interstellar Pickup Ions
Although there is a lot known about the physics that dictates the movement of the planets and starts throughout the night sky, little is known about the medium which encompasses these heavenly bodies. Let us consider our own solar system as an example of this. The reason for the orbit of planets around the Sun has been well known for quite some time. In addition to this, the predictability of t...
متن کاملUsing ARTEMIS pickup ion observations to place constraints on the lunar atmosphere
[1] We present a method for deriving constraints on the structure and composition of the lunar atmosphere by using pickup ion measurements from ARTEMIS, mapping observed fluxes from the spacecraft location to derive production rates at the source region, and fitting to a parameterized neutral atmosphere model. We apply this technique to ~12min of high-resolution burst data collected by ARTEMIS ...
