High-latitude Observations of Dissipation-range Turbulence by the Ulysses Spacecraft during the Solar Minimum of 1993–96: The Spectral Break and Anisotropy

Autor: Abigale S. Watson, Charles W. Smith, Anastasia V. Marchuk, Matthew R. Argall, Colin J. Joyce, Philip A. Isenberg, Bernard J. Vasquez, Nathan A. Schwadron, Neil Murphy

Publikováno v: The Astrophysical Journal, Vol 974, Iss 1, p 94 (2024)

We examine Ulysses magnetic field observations from 1993 to 1996 as the spacecraft made its first fast-latitude scan from the southern to the northern hemisphere. Most of the observations we use are representative of high-latitude solar minimum condi

Turbulence Driving by Interstellar Pickup Ions in the Outer Solar Wind

Autor: Philip A. Isenberg, Bernard J. Vasquez, Charles W. Smith

Publikováno v: The Astrophysical Journal, Vol 944, Iss 1, p 84 (2023)

We revisit the question of how the unstable scattering of interstellar pickup ions (PUIs) may drive turbulence in the outer solar wind and why the energy released into fluctuations by this scattering appears to be significantly less than the standard

Low-frequency Waves Due to Newborn Interstellar Pickup Ions Observed from 43 to 47 au by the Voyager 1 Spacecraft

Autor: Lily A. Ercoline, Charles W. Smith, Matthew R. Argall, Colin J. Joyce, Philip A. Isenberg, Bernard J. Vasquez, Nathan A. Schwadron, Justyna M. Sokół, Leonard F. Burlaga

Publikováno v: The Astrophysical Journal, Vol 945, Iss 2, p 168 (2023)

Interstellar neutral atoms enter the heliosphere at a relatively slow speed corresponding to the motion of the Sun through the local interstellar medium, which is approximately 25 km s ^−1 . Neutral hydrogen atoms enter from the approximate locatio

High-latitude Observations of Inertial-range Turbulence by the Ulysses Spacecraft During the Solar Minimum of 1993–96

Autor: Abigale S. Watson, Charles W. Smith, Anastasia V. Marchuk, Matthew R. Argall, Colin J. Joyce, Philip A. Isenberg, Bernard J. Vasquez, Nathan A. Schwadron, Maciej Bzowski, Marzena A. Kubiak, Neil Murphy

Publikováno v: The Astrophysical Journal. 927:43

We have examined Ulysses magnetic field measurements for the years 1993 through 1996 as the spacecraft moved sunward from 5 au at high southern latitudes, passing through perihelion during the first fast-latitude scan to achieve high northern latitud

Low-frequency Waves due to Newborn Interstellar Pickup He+ Observed by the Ulysses Spacecraft

Autor: Anastasia V. Marchuk, Charles W. Smith, Abigale S. Watson, Matthew R. Argall, Colin J. Joyce, Philip A. Isenberg, Bernard J. Vasquez, Nathan A. Schwadron, Maciej Bzowski, Marzena A. Kubiak, Neil Murphy

Publikováno v: The Astrophysical Journal. 923:185

We have surveyed magnetic field data from the Ulysses spacecraft and found examples of magnetic waves with the expected characteristics that point to excitation by newborn pickup He+. With interstellar neutrals as the likely source for the pickup ion

Perpendicular Ion Heating by Cyclotron Resonant Dissipation of Turbulently Generated Kinetic Alfv\'en Waves in the Solar Wind

Autor: Bernard J. Vasquez, Philip A. Isenberg

Solar wind ions are observed to be heated in the directions perpendicular to the large-scale magnetic field, with preferential heating given to heavy ions. In the solar corona, this heating may be responsible for the generation of the wind itself. It
