The Position/Structure Stability of Four ICRF2 Sources
Ed Fomalont, Kenneth Johnston, Alan Fey +3
Four close radio sources in the International Celestial Reference Frame (ICRF) catalog were observed using phase referencing with the VLBA at 43, 23 and 8.6 GHz, and with VERA at 2…
The Solar Neighborhood XXIII CCD Photometric Distance Estimates of SCR Targets -- 77 M Dwarf Systems within 25 Parsecs
Jennifer G. Winters, Todd J. Henry, Wei-Chun Jao +3
We present CCD photometric distance estimates of 100 SCR (SuperCOSMOS RECONS) systems with 0$\farcs$18/yr, 28 of which are new discoveries previously unpublished in this…
Radio Observations of HD 80606 Near Planetary Periastron
T. J. W. Lazio, P. D. Shankland, W. M. Farrell +1
This paper reports Very Large Array observations at 325 and 1425 MHz (90cm and 20cm) during and near the periastron passage of HD 80606b on 2007 November 20. We obtain flux density…
The PHASES Differential Astrometry Data Archive. V. Candidate Substellar Companions to Binary Systems
Matthew W. Muterspaugh, Benjamin F. Lane, S. R. Kulkarni +7
The Palomar High-precision Astrometric Search for Exoplanet Systems monitored 51 subarcsecond binary systems to evaluate whether tertiary companions as small as Jovian planets orbi…
The PHASES Differential Astrometry Data Archive IV: The Triple Star Systems 63 Gem A and HR 2896
Matthew W. Muterspaugh, Francis C. Fekel, Benjamin F. Lane +7
(Abridged) Differential astrometry measurements from the Palomar High-precision Astrometric Search for Exoplanet Systems (PHASES) are used to constrain the astrometric orbit of the…
The PHASES Differential Astrometry Data Archive. II. Updated Binary Star Orbits and a Long Period Eclipsing Binary
Matthew W. Muterspaugh, William I. Hartkopf, Benjamin F. Lane +8
Differential astrometry measurements from the Palomar High-precision Astrometric Search for Exoplanet Systems have been combined with lower precision single-aperture measurements c…
