| Zusammenfassung |
| Studies on terrestrial oxygen ion (O+) escape into the interplanetary
space have considered a number of different escape paths. Recent observations
however suggest a yet insufficiently investigated additional escape route
for hot O+: along open magnetic field lines in the high altitude cusp and
mantle. Here we present a statistical study on O+ flux in the
high-latitude dayside magnetosheath. The O+ is generally seen relatively
close to the magnetopause, consistent with observations of O+ flowing
primarily tangentially to the magnetopause. We estimate the total escape flux
in this region to be ~ 7 × 1024 s−1, implying this
escape route to significantly contribute to the overall total O+ loss into
interplanetary space. |
