Recent estimates of the bulk density of the largest M-type asteroid 16 Psyche (1.4 and 1.8 g/cm3) seem to be too low for asteroids of this type. The interpretation of such low densities for the asteroid 16 Psyche with its increased metal content led to estimates of its macroporosity of 70%. In the present paper, it has been shown that the extremely low density estimates are caused primarily by the usage of a very high value of the IRAS diameter of the asteroid (D = 264 km, which corresponds to… Expand
Evidence of a metal-rich surface for the asteroid (16) Psyche from interferometric observations in the thermal infrared
Abstract 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 InterferometricExpand
Understanding Asteroid 16 Psyche’s composition through 3D impact crater modeling
Abstract Asteroid 16 Psyche is the largest M-type (metallic) Main Belt Asteroid (MBA). Radar albedo data indicate Psyche’s surface is rich in metallic content, but estimates for Psyche’s bulkExpand
A radar survey of M- and X-class asteroids
Abstract We observed ten M- and X-class main-belt asteroids with the Arecibo Observatory's S-band (12.6 cm) radar. The X-class asteroids were targeted based on their albedos or other properties whichExpand
The triaxial ellipsoid size, density, and rotational pole of asteroid (16) Psyche from Keck and Gemini AO observations 2004-2015
Abstract We analyze a comprehensive set of our adaptive optics (AO) images taken at the 10 m W. M. Keck telescope and the 8 m Gemini telescope to derive values for the size, shape, and rotationalExpand
Origin of volatiles in the main belt
We propose a scenario for the formation of the main belt in which asteroids incorporated icy particles formed in the outer solar nebula. We calculate the composition of icy planetesimals formedExpand

A radar survey of M- and X-class asteroids II. Summary and synthesis
Abstract Using the S-band radar at Arecibo Observatory, we observed six new M-class main-belt asteroids (MBAs), and re-observed one, bringing the total number of Tholen M-class asteroids observedExpand
Pre-flyby estimates of the precision of the mass determination of asteroid (21) Lutetia from Rosetta radio tracking
The Rosetta spacecraft will fly by its second target asteroid (21) Lutetia on 10 July 2010. Simulations based on the currently known size of Lutetia and assumptions on the bulk density show thatExpand
Structure and Evolution of Kuiper Belt Objects and Dwarf Planets
Kuiper belt objects (KBOs) accreted from a melange of volatile ices, carbonaceous matter, and rock of mixed interstellar and solar nebular provenance. The transneptunian region, where this accretionExpand
Cometary masses derived from non‐gravitational forces
We compute masses and densities for ten periodic comets with known sizes: 1P/Halley, 2P/Encke, 6P/d’Arrest, 9P/Tempel 1, 10P/Tempel 2, 19P/Borrelly, 22P/Kopff, 46P/Wirtanen, 67P/Churyumov-GerasimenkoExpand


Mass and density of asteroids (16) Psyche and (121) Hermione
The first determination of the mass of asteroids (16) Psyche and (121) Hermione is reported. From an encounter with asteroid (94) Aurora, the value (8.7 ± 2.6) 10−12 M (solar mass) was derived forExpand
On the surface composition of the M-type asteroids
Abstract A wide program of photometric and polarimetric observations for the largest M-type asteroids was carried out at the Astronomical Observatory of Kharkov University in 1978–1986. In order toExpand
Physical properties of M class asteroids
Abstract The available data on M class asteroids have been collected and analysed. The possible number of M-asteroids in the main asteroid belt larger than 30 km was estimated to be about 90 objects.Expand
Spectral Features of M-Asteroids: 75 Eurydike and 201 Penelope
Abstract Spectrophotometric data for the 0.338- to 0.762-μm region on the main-belt M-asteroids 75 Eurydike and 201 Penelope at small phase angles have been obtained. The spectral observations of 201Expand
The nature of the M-type asteroids from optical polarimetry
Abstract The curves of polarization of the M-type asteroids are not reproduced by silicate rocks in any surface textures; nor do they correspond to metallic fractures. They fit with powders of 20 toExpand
3-μm Spectrophotometric Survey of M- and E-Class Asteroids
Many asteroids show absorption features diagnostic of hydrated minerals in the 3-μm region of the spectrum. Reflectance studies in this region can determine the hydration state of surface mineralsExpand
Physical studies of asteroids: XVII. JHK photometry of selected main-belt and near-Earth asteroids☆
Abstract JHK photometry of 74 main-belt and 3 near-Earth asteroids has been performed. We interpret our data together with previously published JHK measurements, in all a sample of 151 asteroids, andExpand
A New Calibration of the Polarimetric Albedo Scale of Asteroids
Abstract The constants of the empirical dependences, used for defining asteroid albedos from polarimetric observations, were determined almost 20 years ago. Since then, asteroid albedos have beenExpand
