We present the discovery of a new satellite of asteroid (130) Elektra—S/2014 (130) 1—in differential imaging and in integral field spectroscopy data over multiple epochs obtained with Spectro-Polarimetric High-contrast Exoplanet Research/Very Large Telescope. This new (second) moonlet of Elektra is about 2 km across, on an eccentric orbit, and about 500 km away from the primary. For a comparative study, we also observed another triple asteroid system, (93) Minerva. For both systems, component… 
Detection of a Satellite of the Trojan Asteroid (3548) Eurybates—A Lucy Mission Target
The discovery of a satellite of the Trojan asteroid Eurybates is described in images obtained with the Hubble Space Telescope and provides an opportunity for a significant expansion of the scientific return from this encounter.
Physical, spectral, and dynamical properties of asteroid (107) Camilla and its satellites
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) Elektra
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.
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 been
(16) Psyche: A mesosiderite-like asteroid?
Context. Asteroid (16) Psyche is the target of the NASA Psyche mission. It is considered one of the few main-belt bodies that could be an exposed proto-planetary metallic core and that would thus be
Connecting asteroids and meteorites with visible and near-infrared spectroscopy
precision: a fast python pipeline for high-contrast imaging – application to SPHERE observations of the red supergiant VX Sagitariae
The search for extrasolar planets has driven rapid advances in instrumentation, resulting in cameras such as SPHERE at the VLT, GPI at Gemini South and SCExAO at Subaru, capable of achieving very

Determination of binary asteroid orbits with a genetic-based algorithm
Aims: Over the past decade, discoveries of multiple and binary asteroid systems have played a significant role in our general understanding of small solar system bodies. Direct observations of
The infra-red dual imaging and spectrograph for SPHERE: design and performance
The SPHERE (Spectro-Polarimetric High-contrast Exoplanet Research) planet finder instrument for ESO's VLT telescope, scheduled for first light in 2011, aims to detect giant extra-solar planets in the
High-contrast imaging of Sirius A with VLT/SPHERE: looking for giant planets down to one astronomical unit
Sirius has always attracted a lot of scientific interest, especially after the discovery of a companion white dwarf at the end of the 19th century. Very early on, the existence of a potential third
SPHERE: a planet finder instrument for the VLT
Direct detection and spectral characterization of extra-solar planets is one of the most exciting but also one of the most challenging areas in modern astronomy. The challenge consists in the very
