COSPAR20 – C3.3 – Imaging the Planets in X-rays

As someone we believe may have a scientific interest in the various
topics it covers, we would like to draw your attention to a special
session we are organizing at COSPAR 2020, which will be held in Sydney 
Australia from 15-22 August 2020, covering the broad topic of solar and
stellar winds interacting with obstacles and the soft X-ray emission
that results:

All space science disciplines, heliophysics, planetary, and
astrophysics, have an interest in understanding the complex nature of
solar and stellar winds interacting with obstacles. Within recent
decades, observations, modeling, and theory have shown that these
interactions can be imaged in X-rays. Within our solar system, Earth,
Earth’s moon, comets, Mars, Venus, Jupiter, and Pluto are known to emit
X-rays resulting from their interactions with the solar wind.
Furthermore, the solar wind itself emits soft X-rays when it interacts 
with interstellar neutrals entering the heliosphere to create a
background emission for solar system objects. Similarly, stellar winds 
interacting with exoplanets emit soft X-rays outside our heliosphere.
All these emissions are superimposed upon and must be separated from the
cosmic soft X-ray background, which is itself of great interest to
astrophysicists. We encourage all session submissions addressing or
related to solar and/or stellar winds generating X-ray emissions.
Possible topics include, but are not limited to, observations, modeling,
theory, instrument concepts, and missions in both formulation and
implementation, particularly the ESA/CAS SMILE mission.

If you would like to participate in this session, we encourage you to
submit an abstract. Note that COSPAR does not have a “one-abstract
policy,” so submitting an abstract to this session will not preclude
submitting another abstract on a different topic to another session. In
fact, the web site for COSPAR 2020 abstract submission is open now at:

and there is no better time than right now to submit an abstract – hope
you will. Looking forward to seeing and hearing from you in Sydney next
summer!!
