Pickup Ions From Various Sources Within the Heliosphere

Session ID#: 157356

Session Description:

This session focuses on current modeling and observations of pickup ion (PUI) populations present within the heliosphere. PUIs are produced by the ionization of neutral atoms from various sources, e.g., interstellar gas, interplanetary dust, planetary exospheres, or satellites. The most prominent ion population within the heliosphere is the solar wind, which originates from the Sun and is composed of protons and multiply-charged ions. However, most PUI populations do not originate from the Sun and, depending on their source, are called interstellar, planetary, or inner source PUIs.

The ions produced in these various locales engage in gyratory motion with the local magnetic field regardless of the source. Because of this associated motion, PUIs provide information about the remote and in situ physical processes affecting their environments and their composition. We encourage abstract submissions that advance our understanding of PUIs in the Solar System.
