Title:

 

Solar Wind Charge Exchange Soft Xray Imaging in the Solar System

 

Abstract

 

X-ray emission from Solar Wind Charge Exchange (SWCX) recombination is ubiquitous. It occurs in planetary atmospheres, comets, interplanetary space, and in the Earth’s exosphere,  while evidence for extrasolar charge exchange emission has been observed in supernova remnants, galaxies and galaxy clusters. Consequently, the heliophysics, planetary science, and astrophysics communities all have an interest in SWCX.  The cross-disciplinary nature of the subject requires an unusually high degree of cooperation and coordination across these disciplines. An ISSI workshop provides a unique and ideal forum for bringing together experts from across Europe, the United States, and Japan from the fields of heliophysics, astrophysics, and planetary science to (1) assess the current state of SWCX soft X-ray research including relevant laboratory and theoretical atomic collision processes, (2) tackle outstanding problems in theory, observation, and modeling, and (3) define the direction of future research.

 

Our purpose is to advance understanding of the basic processes through which the charge exchange interaction with neutral gas produces soft X-ray photons within the solar system by bringing together at ISSI European, American, and Japanese experts from the heliophysics, planetary science, and astrophysics disciplines. We will synthesize models and observations, identify fundamental science questions in heliophysics, planetary science, and astrophysics that can be addressed with SWCX soft X-ray imaging, and determine the current and required capability of SWCX soft X-ray instrumentation to solve these problems.
