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 occultation measurements further constrain asteroid shapes and allow size estimates.Aims. We aim to use all the available disk-resolved images of approximately forty asteroids obtained by the Near-InfraRed Camera (Nirc2) mounted on the W.M. Keck II telescope together with the disk-integrated photometry and stellar… Expand
Homogeneous internal structure of CM-like asteroid (41) Daphne
Context. CM-like asteroids (Ch and Cgh classes) are a major population within the broader C-complex, encompassing about 10% of the mass of the main asteroid belt. Their internal structure has beenExpand
The AKARI IRC asteroid flux catalogue: updated diameters and albedos
The AKARI IRC All-sky survey provided more than twenty thousand thermal infrared observations of over five thousand asteroids. Diameters and albedos were obtained by fitting an empirically calibratedExpand
Precise astrometry and diameters of asteroids from occultations – a data set of observations and their interpretation
Occultations of stars by asteroids have been observed since 1961, increasing from a very small number to now over 500 annually. We have created and regularly maintain a growing data-set of more thanExpand
Spin states of asteroids in the Eos collisional family
Abstract Eos family was created during a catastrophic impact about 1.3 Gyr ago. Rotation states of individual family members contain information about the history of the whole population. We aim toExpand
Photometric survey, modelling, and scaling of long-period and low-amplitude asteroids
The available set of spin and shape modelled asteroids is strongly biased against slowly rotating targets and those with low lightcurve amplitudes. As a consequence of these selection effects, theExpand
Multitechnique Characterization of Binary Asteroids
Binary asteroids represent a natural laboratory to gather crucial information on small bodiesof the Solar System, providing an overview of the formation and evolution mechanisms of these objects.Expand
The shape of (7) Iris as evidence of an ancient large impact?
Context. Asteroid (7) Iris is an ideal target for disk-resolved imaging owing to its brightness (V ~ 7–8) and large angular size of 0.33′′ during its apparitions. Iris is believed to belong to theExpand
Physical, spectral, and dynamical properties of asteroid (107) Camilla and its satellites
The population of large 100+ km asteroids is thought to be primordial. As such, they are the most direct witnesses of the early history of our Solar System available. Those among them with satellitesExpand
Shape and spin determination of Barbarian asteroids
Context. The so-called Barbarian asteroids share peculiar, but common polarimetric properties, probably related to both their shape and composition. They are named after (234) Barbara, the first onExpand
The impact crater at the origin of the Julia family detected with VLT/SPHERE?
Context. The vast majority of the geophysical and geological constraints (e.g., internal structure, cratering history) for main-belt asteroids have so far been obtained via dedicated interplanetaryExpand


New and updated convex shape models of asteroids based on optical data from a large collaboration network
Context. Asteroid modeling efforts in the last decade resulted in a comprehensive dataset of almost 400 convex shape models and their rotation states. These efforts already provided deep insight intoExpand
Shape model of asteroid (130) Elektra from optical photometry and disk-resolved images from VLT/SPHERE and Nirc2/Keck
Asteroid (130) Elektra belongs to one of the six known triple asteroids in the main belt, so its mass has been reliably determined. We aim to use all available disk-resolved images of (130) ElektraExpand
Asteroids’ physical models from combined dense and sparse photometry and scaling of the YORP effect by the observed obliquity distribution
The larger number of models of asteroid shapes and their rotational states derived by the lightcurve inversion give us better insight into both the nature of individual objects and the whole asteroidExpand
Asteroid models from combined sparse and dense photometric data
Aims. Shape and spin state are basic physical characteristics of a n asteroid. They can be derived from disc-integrated photometry by the lightcurve inversion method. Increasing the number ofExpand
Sizes of main-belt asteroids by combining shape models and Keck adaptive optics observations
Abstract We select 50 main-belt asteroids with a diameter between 20 and 400 km for which we have (i) shape models derived by the lightcurve inversion method and (ii) resolved observations of goodExpand
ADAM: a general method for using various data types in asteroid reconstruction
We introduce ADAM, the All-Data Asteroid Modelling algorithm. ADAM is simple and universal since it handles all disk-resolved data types (adaptive optics or other images, interferometry, andExpand
Main Belt Asteroids with WISE/NEOWISE. I. Preliminary Albedos and Diameters
We present initial results from the Wide-field Infrared Survey Explorer (WISE), a four-band all-sky thermal infrared survey that produces data well suited for measuring the physical properties ofExpand
DAMIT: a database of asteroid models
Context. Apart from a few targets that were directly imaged by spacecraft, remote sensing techniques are the main source of information about the basic physical properties of asteroids, such as theExpand
Combining asteroid models derived by lightcurve inversion with asteroidal occultation silhouettes
Abstract Asteroid sizes can be directly measured by observing occultations of stars by asteroids. When there are enough observations across the path of the shadow, the asteroid’s projected silhouetteExpand
A study of asteroid pole-latitude distribution based on an extended set of shape models derived by the lightcurve inversion method
Context. In the past decade, more than one hundred asteroid models were derived using the lightcurve inversion method. Measured by the number of derived models, lightcurve inversion has become theExpand
