The High Angular Resolution Multiplicity of Massive Stars
Brian D. Mason, William I. Hartkopf, Douglas R. Gies +2
We present the results of a speckle interferometric survey of Galactic massive stars that complements and expands upon a similar survey made over a decade ago. The speckle observat…
Morphological evidence for azimuthal variations of the cosmic ray ion acceleration at the blast wave of SN 1006
Gamil Cassam-Chenai, John P. Hughes, Estela M. Reynoso +2
Using radio, X-ray and optical observations, we present evidence for morphological changes due to efficient cosmic ray ion acceleration in the structure of the southeastern region…
Correlation between X-ray Lightcurve Shape and Radio Arrival Time in the Vela Pulsar
A. Lommen, J. Donovan, C. Gwinn +6
We report the results of simultaneous observations of the Vela pulsar in X-rays and radio from the RXTE satellite and the Mount Pleasant Radio Observatory in Tasmania. We sought co…
The B-Supergiant Components of the Double-Lined Binary HD1383
T. S. Boyajian, D. R. Gies, M. E. Helsel +4
We present new results from a study of high quality, red spectra of the massive binary star system HD 1383 (B0.5 Ib + B0.5 Ib). We determined radial velocities and revised orbital…
Cosmic Ray Acceleration at the Forward Shock in Tycho's Supernova Remnant: Evidence from Chandra X-ray Observations
J. S. Warren, J. P. Hughes, C. Badenes +7
We present evidence for cosmic ray acceleration at the forward shock in Tycho's supernova remnant (SNR) from three X-ray observables: (1) the proximity of the contact discontinuity…
The VSOP 5 GHz AGN Survey II. Data Calibration and Imaging
J. E. J. Lovell, G. A. Moellenbrock, S. Horiuchi +18
The VSOP mission is a Japanese-led project to study radio sources with sub-milliarcsecond angular resolution using an orbiting 8-m telescope, HALCA and global arrays of Earth-based…
