Are the sungrazing comets the inner source of pickup ions and energetic neutral atoms?
We show arguments that at least part of the inner source of pickup ions and energetic neutral atoms (∼ 1 keV) might be the material released by sungrazing comets. Based on the monthly apparition statistics we postulate that the actual number of sungrazing comets may be even higher than observed. We point out that an overwhelming majority of the observed sungrazers belong to the Kreutz group of ...
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 کاملThe outer source of pickup ions and anomalous cosmic rays
[1] The traditionally accepted source of Anomalous Cosmic Rays (ACRs) is neutral atoms penetrating the heliosphere from the local interstellar cloud (LIC). The ACR composition should be depleted in easily ionized atoms such as C, Si, and Fe. However, significant fluxes of these ions are observed in ACRs and their source has not been previously identified. We show that there is an ‘‘outer source...
متن کاملInterstellar and Inner Source Pickup Ions Observed with Swics on Ulysses
Many species of pickup ions, both of interstellar origin and from an inner, distributed source have been discovered using data from the Solar Wind Ion Composition Spectrometer (SWICS) on Ulysses. Velocity distribution functions of these ions were measured for the first time over heliocentric distances between 1.35 and 5.4 AU, both at high and low latitudes, and in the disturbed slow solar wind ...
