太阳轨道器原位探测C/2019 Y4 ATLAS彗星的展望

Prospects for the In Situ detection of Comet C/2019 Y4 ATLAS by Solar Orbiter

Geraint H. Jones, Qasim Afghan, Oliver Price

摘要:

欧洲航天局的太阳轨道器航天器将于2020年5月底和6月初在彗星C/2019 Y 4(ATLAS)的位置下游附近通过。我们预测,宇宙飞船可能会在2020年5月31日至6月1日之间遇到彗星的离子尾,而彗星的尘埃尾可能会在2020年6月6日穿过。我们概述了太阳风的特点和尘埃颗粒碰撞,航天器的仪器可能会发现时,穿越彗星的两个尾巴。太阳轨道器也将在2020年5月22日通过C/2020 F8(SWAN)的轨道路径,但我们认为它不太可能探测到与该彗星相关的任何物质。

英文摘要:

The European Space Agency's Solar Orbiter spacecraft will pass approximately downstream of the position of comet C/2019 Y4 (ATLAS) in late May and early June 2020. We predict that the spacecraft may encounter the comet's ion tail around 2020 May 31-June 1, and that the comet's dust tail may be crossed on 2020 June 6. We outline the solar wind features and dust grain collisions that the spacecraft's instruments may detect when crossing the comet's two tails. Solar Orbiter will also pass close to the orbital path of C/2020 F8 (SWAN) on 2020 May 22, but we believe that it is unlikely to detect any material associated with that comet.
