Inhomogeneity within Local Interstellar Clouds
Redfield, Seth; Linsky, Jeffrey L.; Ryder, Diana +1 more
Analysis of interstellar absorption lines observed in high-resolution Hubble Space Telescope spectra of nearby stars provides temperatures, turbulent velocities, and kinetic properties of warm interstellar clouds. A new analysis of 97 interstellar-velocity components reveals a wide range of temperatures and turbulent velocities within the Local In…
Determination of Position of Jupiter From Very-Long Baseline Interferometry Observations of ULYSSES
Mannucci, A. J.; Folkner, W. M.; McElrath, T. P.
Very-long baseline interferometry (VLBI) observations of the Ulysses spacecraft near its encounter with Jupiter on 1992 February 8 were made to determine the angular position of Jupiter with respect to well known extragalactic radio sources. Spacecraft range and Doppler data were used to determine the position of the spacecraft with respect to Jup…
