Approaches for Retrieving Sulfur Species Abundances from Dual X/Ka Band Radio Occultations of Venus with EnVision and VERITAS
Alex B. Akins, Tatiana M. Bocanegra-Bahamón, Kuo-Nung Wang +4
The EnVision and VERITAS missions to Venus will fly with X and Ka band telecommunications channels which can be used to conduct radio occultation studies of Venus' atmosphere. Whil…
Accurate Ground-based Near-Earth-Asteroid Astrometry using Synthetic Tracking
Chengxing Zhai, Michael Shao, Navtej S. Saini +13
Accurate astrometry is crucial for determining orbits of near-Earth-asteroids (NEAs) and therefore better tracking them. This paper reports on a demonstration of 10 milliarcsecond-…
Dynamical masses of the low-mass stellar binary ABDoradusB
R. Azulay, J. C. Guirado, J. M. Marcaide +8
Context. ABDoradus is the main system of the ABDoradus moving group. It is a quadruple system formed by two widely separated binaries of pre-main-sequence (PMS) stars: ABDor A/C an…
A Decade of SN1993J: Discovery of Wavelength Effects in the Expansion Rate
J. M. Marcaide, I. Marti-Vidal, A. Alberdi +15
We have studied the growth of the shell-like radio structure of supernova SN1993J in M81 from September 1993 through October 2003 with very-long-baseline interferometry (VLBI) obse…
Ten milliparsec-scale structure of the nucleus region in Centaurus A
Shinji Horiuchi, David L. Meier, Robert A. Preston +1
We present the results of a VLBI Space Observatory Programme (VSOP) observation of the subparsec structure in Centaurus A at 4.9 GHz. Owing to its proximity, our Centaurus A space-…
CHANDRA Observations of X-ray Jet Structure on kpc to Mpc Scales
D. A. Schwartz, H. L. Marshall, B. P. Miller +7
With its exquisite spatial resolution of better than 0.5 arcsecond, the Chandra observatory is uniquely capable of resolving and studying the spatial structure of extragalactic X-r…
