PLASMA NEAR THE HELIOSHEATH: OBSERVATIONS AND INTERPRETATIONS [PDF]

open access: yesThe Astrophysical Journal, 2010
Voyager 2 (V2) has observed heliosheath plasma since 2007 August. The plasma flux decreases by 25% before the termination shock (TS), then, as V2 moved into the heliosheath, the plasma density, temperature, and flux all decreased by an additional factor of 2. We suggest three effects combine to cause these decreases.

A Predicted Small and Round Heliosphere [PDF]

open access: yes, 2018
The shape of the solar wind bubble within the interstellar medium, the so-called heliosphere, has been explored over six decades. As the Sun moves through the surrounding partially-ionized medium, neutral hydrogen atoms penetrate the heliosphere, and ...

Scatter-free pickup ions beyond the heliopause as a model for the Interstellar Boundary Explorer (IBEX) ribbon

open access: yes, 2010
We present new kinetic-gasdynamic model of the solar wind interaction with the local interstellar medium. The model incorporates several processes suggested by McComas et al.

The Intensities of Cosmic Ray H and He Nuclei at ~250 MeV/nuc Measured by Voyagers 1 and 2 - Using these Intensities to Determine the Solar Modulation Parameter in the Inner Heliosphere and the Heliosheath Over a 40 Year Time Period [PDF]

open access: yes, 2017
We have determined the solar modulation potential, phi, vs. time that is observed at Voyager 1 and 2 from measurements of the H and He nuclei intensities at a common energy of 250 MeVnuc. The H nuclei have a rigidity 0.7 GV, the He nuclei 1.4 GV.

Tentative Identification of Interstellar Dust in the Nose of the Heliosphere

open access: yes, 2005
Observations of the weak polarization of light from nearby stars, reported by Tinbergen (1982), are consistent with polarization by small, radius

Lyα Absorption from Heliosheath Neutrals [PDF]

open access: yesThe Astrophysical Journal, 2007
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 heliospheric ...

Warm Breeze from the starboard bow: a new population of neutral helium in the heliosphere

open access: yes, 2014
We investigate the signals from neutral He atoms observed from Earth orbit in 2010 by IBEX. The full He signal observed during the 2010 observation season can be explained as a superposition of pristine neutral interstellar He gas and an additional ...

The Magnetic Field Structure in the Heliosheath

open access: yesThe Astrophysical Journal, 2005
The magnetic field observed in a fluctuating, dynamical heliosheath will differ considerably from that in a static heliosheath. In particular, the time between current-sheet crossings (sectors) is quite sensitive to the radial speed of the solar wind termination shock.
