Abstract
ONLY recently-published observations permit a useful estimate of the total accretion of interstellar matter (ISM) by the Sun since it became a main sequence star. Using measurements from the OAO-2 satellite, Jenkins and Savage1 conclude that “… possibly the most secure estimate of the amount of hydrogen within 1 kpc of the Sun is … an overall density nH (total) = 1.5 atoms cm−3 (in the form of protons, atoms and molecules)”. Using this number we suggest here a possible explanation of the low observed solar neutrino rate.
