Multi-Wavelength Observations of Supernova 2011ei: Time-Dependent Classification of Type IIb and Ib Supernovae and Implications for their Progenitors
D. Milisavljevic, R. Margutti, A. M. Soderberg +39
We present X-ray, UV/optical, and radio observations of the stripped-envelope, core-collapse supernova (SN) 2011ei, one of the least luminous SNe IIb or Ib observed to date. Our ob…
VLBI for Gravity Probe B. VII. The Evolution of the Radio Structure of IM Pegasi
M. F. Bietenholz, N. Bartel, D. E. Lebach +3
We present measurements of the total radio flux density as well as very-long-baseline interferometry (VLBI) images of the star, IM Pegasi, which was used as the guide star for the…
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. II. Monitoring of the Structure of the Reference Sources 3C 454.3, B2250+194, and B2252+172
R. R. Ransom, N. Bartel, M. F. Bietenholz +5
We used 8.4 GHz VLBI images obtained at up to 35 epochs between 1997 and 2005 to examine the radio structures of the main reference source, 3C 454.3, and two secondary reference so…
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…
