Quadrantids 2021: our best wishes for the start of a new year
This astronomical event will be broadcast live in the early hours of January 3rd from the Canary Observatories, via the sky-live.tv channel, with the...
Regional Photometric Modeling of Asteroid (101955) Bennu
We present a regional photometric analysis of asteroid (101955) Bennu, using image data from the MapCam color imager of the OSIRIS-REx Camera Suite (OCAMS)...
Resurfacing processes constrained by crater distribution on Ryugu
Understanding the geological modification processes on asteroids is fundamental for elucidating their surface evolution. Images of small asteroids from...
Resurfacing processes on asteroid (162173) Ryugu caused by an artificial impact of Hayabusa2's Small Carry-on Impactor
The resurfacing process on Ryugu accompanying the artificial impact crater formation by Hayabusa2's Small Carry-on Impactor (SCI) was studied by comparing pre-...
Rotational fission of trans-Neptunian objects: the case of Haumea
We present several lines of evidence, based on different kinds of observations, and we conclude that it is likely that rotational fission has occurred for a...
Samples returned from the asteroid Ryugu are similar to Ivuna-type carbonaceous meteorites
Carbonaceous meteorites are thought to be fragments of C-type (carbonaceous) asteroids. Samples of the C-type asteroid (162173) Ryugu were retrieved by the...
Scaling slowly rotating asteroids with stellar occultations
Context. As evidenced by recent survey results, the majority of asteroids are slow rotators (spin periods longer than 12 h), but lack spin and shape models...
WD 1145+017 is a unique white dwarf system that has a heavily polluted atmosphere, an infrared excess from a dust disk, numerous broad absorption lines from...
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...
