Orbit injection of planet-crossing asteroids
Fathi Namouni
Solar system Centaurs originate in transneptunian space from where planet orbit crossing events inject their orbits inside the giant planets' domain. Here, we examine this injectio…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): HD 34700 A unveils an inner ring
G. Columba, E. Rigliaco, R. Gratton +18
Context. The study of protoplanetary disks is fundamental to understand their evolution and interaction with the surrounding environment, and to constrain planet formation mechanis…
Euclid: Identification of asteroid streaks in simulated images using deep learning
M. Pöntinen, M. Granvik, A. A. Nucita +114
Up to 150000 asteroids will be visible in the images of the ESA Euclid space telescope, and the instruments of Euclid offer multiband visual to near-infrared photometry and slitles…
Close-to-fission dumbbell Jupiter-Trojan (17365) Thymbraeus
B. Carry, P. Descamps, M. Ferrais +11
Every population of small bodies in the Solar system contains a sizable fraction of multiple systems. Among these, the Jupiter Trojans have the lowest number of known binary system…
Gaia view of primitive inner-belt asteroid families: Searching for the origins of asteroids Bennu and Ryugu
Marco Delbo, Chrysa Avdellidou, Kevin J. Walsh
Near-Earth asteroids Ryugu and Bennu, were visited, characterised, and sampled by the Hayabusa2 and OSIRIS-REx missions: remote sensing data and sample return analysis showed that…
Dynamical detection of a companion driving a spiral arm in a protoplanetary disk
Chen Xie, Bin B. Ren, Ruobing Dong +6
Radio and near-infrared observations have observed dozens of protoplanetary disks that host spiral arm features. Numerical simulations have shown that companions may excite spiral…
