The small bodies of our solar system are the remnants of the early stages of planetary
formation. A considerable amount of information regarding the processes that occurred …

Amateur contributions to professional publications have increased exponentially over the
last decades in the field of planetary astronomy. Here we review the different domains of the …

Using the S-band radar at Arecibo Observatory, we observed 16 Psyche, the largest M-class
asteroid in the main belt. We obtained 18 radar imaging and 6 continuous wave runs in …

In the past decade, the number of known binary near-Earth asteroids has more than
quadrupled and the number of known large main-belt asteroids with satellites has doubled …

Using precise relative astrometry from the Hubble Space Telescope and the WM Keck
Telescope, we have determined the orbits and masses of the two dynamically interacting …

Abstract Knowledge of water in the solar system is important for the understanding of a wide
range of evolutionary processes and the thermal history of the solar system. To explore the …

Context. Disk-integrated photometric data of asteroids do not contain accurate information
on shape details or size scale. Additional data such as disk-resolved images or stellar …

As an application of our recent observational error model, we present the astrometric
masses of 26 main-belt asteroids. We also present an integrated ephemeris of 300 large …

To take full advantage of the September 2008 opposition passage of the M-type Asteroid
(216) Kleopatra, we have used near-infrared adaptive optics (AO) imaging with the WM Keck …

We describe the first determination of thermal properties and size of the M-type Asteroid (16)
Psyche from interferometric observations obtained with the Mid-Infrared Interferometric …
