Monthly notices of the Royal Astronomical Society, 2023 The ephemerides of minor planets are computed on the basis of astrometric observations. The asteroid Orbit Determination process requires these observations to be properly weighted to take into account the expected accuracy of the data. If not directly

Nature Communications, 2022 Asteroid interiors play a key role in our understanding of asteroid formation and evolution. As no direct interior probing has been done yet, characterisation of asteroids’ interiors relies on interpretations of external properties.

ASTEROIDS: A Stixel Tracking Extrapolation-Based Relevant Obstacle Impact Detection System
IEEE Transactions on Intelligent Vehicles, 2020 This paper presents a vision-based collision-warning system for ADAS in intelligent vehicles, with a focus on urban scenarios. In most current systems, collision warnings are based on radar, or on monocular vision using pattern recognition.

Uninterrupted optical light curves of main-belt asteroids from the K2 mission [PDF]
, 2016 Context. Because the second reaction wheel failed, a new mission was conceived for the otherwise healthy Kepler space telescope. In the course of the K2 mission, the telescope is staring at the plane of the Ecliptic.

Hydrodynamics of tsunamis generated by asteroid impact in the Black Sea
Open Physics, 2012 Abstract Two-dimensional and one-dimensional models are used to evaluate the seashore effects of the tsunami generated by an asteroid hitting the deep water in the Eastern region of the Black Sea. The shallow water theory has been used to describe tsunami propagation.

A case of atypical nocardia asteroides sclerouveitis resistant to fourth-generation fluoroquinolones [PDF]
Revista Brasileira de Oftalmologia, 2016 ABSTRACT We describe an unusual case of Nocardia spp scleritis in a health girl resistant to topical fourth-generation fluoroquinolones. Clinically, there was only partial response of the scleritis to initial therapy. Treatment was changed to meropenem intravenously and topical amikacin.

Accuracy of view factor calculations for digital terrain models of comets and asteroids
Astronomy & Astrophysics, 2020 Context. Detailed shape and topographic models coupled with sophisticated thermal physics are critical elements to proper characterization of surfaces of small bodies in our solar system.

Sublimation-induced orbital perturbations of extrasolar active asteroids and comets: application to white dwarf systems [PDF]
, 2015 The metal budgets in some white dwarf (WD) atmospheres reveal that volatile-rich circumstellar bodies must both exist in extrasolar systems and survive the giant branch phases of stellar evolution.

An integrated DEM code for tracing the entire regolith mass movement on asteroids
Monthly notices of the Royal Astronomical SocietyThis paper presents a general strategy for tracking the scale-span movement process of asteroid regolith materials. It achieves the tracking of the mass movement on the asteroid at a realistic scale, under conditions of high-resolution asteroid surface

Temporary Capture of Asteroids by an Eccentric Planet [PDF]
, 2017 We have investigated the probability of temporary capture of asteroids in eccentric orbits by a planet in a circular or eccentric orbit through analytical and numerical calculations.
