... We propose a novel method of studying stellar winds through obser vation of charge exchange­induced X-ray emission. Recent X-ray detections of comets suggest that charge transfer between highly charged ions in the solar wind and neutral gases in cometar y atmospheres is responsible for much or all of the obser ved emission, a hypothesis that has been strengthened by Chandra obser vations of comet C/1999 S4 (LINEAR). ... Likewise, the example wind can be seen at distances well beyond 10 pc. ...
