The obliquity between the stellar spin axis and the planetary orbit, detected via the Rossiter-McLaughlin (RM) effect, is a tracer of the formation history of planetary systems. While obliquity measurements have been extensively applied to hot Jupiters and short-period planets, they remain rare for cold and long-period planets due to observational

Introduction:Small bodies in the trans-Neptunian region are key to understanding Solar System formation and evolution. Trans-Neptunian objects (TNOs) are relics of planetary formation in the outer protoplanetary disk, but most of them were later affected by the giant planet instability and the dynamical evolution of the Solar System, with the

The (617) Patroclus is a binary asteroid system located in the trailing Trojan group (L5) ofJupiter. The two components, Patroclus and Menoetius (the satellite), orbit a common center ofmass and are nearly equal in size. Studies suggest that Jupiter's Trojan asteroids, includingPatroclus and Menoetius, may have originated from the outer solar

We present the first optical-UV spectral systematic analysis of 30 Type 1 active galactic nuclei selected in the far-infrared and X-ray in the Lockman-SpReSO Survey. The sample of faint objects (m B = 19.6–21.8) covers a large redshift range of 0.33 >z > 4.97 with a high signal-to-noise ratio (∼21 on average). A detailed spectral analysis based on

The ExoLife Finder (ELF) is a groundbreaking ground-based facility that will transform exoplanet research through direct imaging and characterisation of terrestrial exoplanets. Our mission is to identify biomarkers within their atmospheres, and we are poised to achieve unparalleled performance levels by leveraging cutting-edge technologies. A

Chemical properties of stellar populations are a key observable that can be used to shed light on the assembly history of galaxies across cosmic time. In this study, we investigate the distribution and origin of chemical elements in different stellar components of simulated Milky Way-like galaxies in relation to their mass assembly history, stellar
