VOYAGER 1, VOYAGER 2, AND PIONEER 10 Ly DATA AND THEIR INTERPRETATION
The Voyager 1 (V1), Voyager 2 (V2), and Pioneer 10 (P10) Ly data sets are three of several diagnostic data sets available for the study of the very local interstellar medium (VLISM). Selected V1 data obtained on 1989 day 279 at heliocentric distance of 39.1 AU in the upstream direction relative to the incoming interstellar neutral hydrogen flow and V2 data obtained on 1990 day 143 at heliocentr...
متن کاملTemporal and spectral variations of anomalous oxygen nuclei measured by Voyager 1 and Voyager 2 in the outer heliosphere
[1] We have studied the temporal and spectral variations of anomalous oxygen nuclei at the Voyager 1 (V1) and 2 (V2) spacecraft in the outer heliosphere from 1990 to the present time in 2006 when V1 is now beyond the heliospheric termination shock. During this time period, the intensities increased from their lowest values in 1990–1991 up to a maximum in 1998–1999 and then decreased rapidly in ...
متن کاملVoyager 2 Observations of Plasmas and Flows
Voyager 2 has crossed through 20 AU of the heliosheath; assuming the same heliosheath thickness as at Voyager 1, it is now two-thirds of the way to the heliopause. The plasma data are generally of good quality, although the increasing flow angle of the plasma makes analysis more difficult. The average plasma speed has remained constant but the flow angles have increased to almost 60◦ in the RT ...
متن کاملVoyager Interstellar Mission
The Voyager Interstellar Mission is exploring the interaction of the heliosphere with the local interstellar medium (LISM). Voyager 1 (V1) and Voyager 2 (V2) are both in the heliosheath, making the first in situ observations of the shocked solar wind beyond the termination shock (TS). The heliosheath extends to the heliopause; beyond the heliopause is the interstellar medium. The goal of the Vo...
متن کاملVoyager 2 Observations of Helium Abundance Enhancements from 1 - 60
The Plasma Science experiment on the Voyager 2 spacecraft recently detected helium abundance enhancements (HAEs) near 60 AU in which the alpha percentage is 10%. These large values may result from solar events related to the rising phase of solar cycle 23. Large He/H ratios are probably the best signature for tracking CMEs through the outer heliosphere. We analyze the high resolution spectra fo...
