VLBI for Gravity Probe B. VI. The Orbit of IM Pegasi and the Location of the Source of Radio Emission
R. R. Ransom, N. Bartel, M. F. Bietenholz +4
We present a physical interpretation for the locations of the sources of radio emission in IM Pegasi (IM Peg, HR 8703), the guide star for the NASA/Stanford relativity mission Grav…
VLBI for Gravity Probe B. IV. A New Astrometric Analysis Technique and a Comparison with Results from Other Techniques
D. E. Lebach, N. Bartel, M. F. Bietenholz +7
When VLBI observations are used to determine the position or motion of a radio source relative to reference sources nearby on the sky, the astrometric information is usually obtain…
VLBI for Gravity Probe B. V. Proper Motion and Parallax of the Guide Star, IM Pegasi
M. I. Ratner, N. Bartel, M. F. Bietenholz +4
We present the principal astrometric results of the very-long-baseline interferometry (VLBI) program undertaken in support of the Gravity Probe B (GP-B) relativity mission. VLBI ob…
VLBI for Gravity Probe B. I. Overview
I. I. Shapiro, N. Bartel, M. F. Bietenholz +4
We describe the NASA/Stanford gyroscope relativity mission, Gravity Probe B (GP-B), and provide an overview of the following series of six astrometric and astrophysical papers that…
