Lyα Absorption from Heliosheath Neutrals

Wood, Brian E.; Linsky, Jeffrey L.; Izmodenov, Vladislav V. +1 more

We assess the information that HST observations of stellar Lyα lines can provide on the heliosheath, the region of the heliosphere between the termination shock and heliopause. To search for evidence of heliosheath absorption, we conduct a systematic inspection of stellar Lyα lines reconstructed after correcting for ISM absorption (and heliospheri…
