Laboratory for Extraterrestrial Physics/692A new stream of interstellar gas
• We interpret the LENA data as evidence of a new stream of interstellar gas.
• The presence of such a stream is being tested and confirmed by other data sets, each the subject of one or more papers:• Neutral solar wind flux
(IMAGE) [Collier et al. 2001]
• Cyclotron waves (ISEE, Wind) [Collier et al., 2002]
• He+ pickup ion observations (ACE)
• X-rays from solar wind interactions (ROSAT)
