Radar and Optical Observations and Physical Modeling of Binary Near-Earth Asteroid 2018 EB Open
We report radar, photometric, and visible-wavelength spectrophotometry observations of NEA 2018 EB obtained in 2018. The radar campaign started at Goldstone (8560 MHz, 3.5 cm) on April 7, and it was followed by more extensive observations …

Shape model and spin-state analysis of PHA contact binary (85990) 1999 JV6 from combined radar and optical observations Open
Context. The potentially hazardous asteroid (85990) 1999 JV6 has been a target of previously published thermal-infrared observations and optical photometry. It has been identified as a promising candidate for possible Yarkovsky-O’Keefe-Rad…

The X/Ka-band 2018b Celestial Reference Frame Open
Observations at X/Ka-band are motivated by their ability to access more compact source mor- phology and reduced core shift relative to observations at the historically standard S/X-band. In addition, the factor of four increase in interfer…

Goldstone Radar Observations of Horseshoe-orbiting Near-Earth Asteroid 2013 BS45, a Potential Mission Target Open
We report radar observations of near-Earth asteroid 2013 BS45 obtained during the 2013 apparition. This object is in a resonant, Earth-like orbit, and it is a backup target for NASA’s NEA Scout mission. 2013 BS45 belongs to the Arjuna orbi…
