Near-Earth asteroid (3200) Phaethon. Characterization of its orbit, spin state, and thermophysical parameters
Context. The near-Earth asteroid (3200) Phaethon is an intriguing object: its perihelion is at only 0.14 au and is associated with the Geminid meteor stream. Aims. We aim to use all availableExpand
The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation
Observations from multiple Earth-based observatories of Haumea passing in front of a distant star (a multi-chord stellar occultation) report the presence of a ring with an opacity of 0.5, which constrains the three-dimensional orientation of Haumesa and its triaxial shape, which is inconsistent with a homogeneous body in hydrostatic equilibrium.

The Dust Environment of Main-Belt Comet P/2010 R2 (La Sagra)
We present a model of the dust environment of Main-Belt Comet P/2010 R2 (La Sagra) from images acquired during the period 2010 October-2011 January. The tails are best simulated by anisotropicExpand
Thermophysical modeling of main-belt asteroids from WISE thermal data
Abstract By means of a varied-shape thermophysical model of Hanus et al. (2015) that takes into account asteroid shape and pole uncertainties, we analyze the thermal infrared data acquired by theExpand
Size and albedo distributions of asteroids in cometary orbits using WISE data
We study the distributions of effective diameter ($D$), beaming parameter ($\eta$), and visible geometric albedo ($p_V$) of asteroids in cometry orbits (ACOs) populations, derived from NASA'sExpand
Images of asteroid (596) Scheila have been acquired at various dates after the discovery of the 2010 outburst. Assuming a short-duration event scenario, as suggested by the quick vanishing of theExpand
Asteroid models reconstructed from the Lowell Photometric Database and WISE data
Information about the spin state of asteroids is important for our understanding of the dynamical processes affecting them. However, spin properties of asteroids are known for only a small fractionExpand
5–14 μm Spitzer spectra of Themis family asteroids
Context. The Themis collisional family is one of the largest and best established families in the main belt. Composed of primitive asteroids, there is evidence that water is likely present in a largeExpand
Differences between the Pallas collisional family and similarly sized B-type asteroids ?
Context. B-type asteroids constitute a peculiar spectral class within the C-complex. Previous work has pointed out the difference between the visible geometric albedos of B-types and those of theExpand
GTC/CanariCam observations of (99942) Apophis
Context. The potentially hazardous asteroid (PHA) (99942) Apophis is one of the most remarkable near-Earth asteroids (NEA) in terms of impact hazard. A good determination of its surface thermalExpand
