Astrophotonics, a specialized branch of integrated optics, is transforming observational astronomy by providing compact and efficient photonic solutions to replace traditional bulky optical systems. Originally stemming from the telecommunication industry, astrophotonics has matured into a distinct field tailored to the demanding requirements of

This paper examines the reliability of the Tremaine-Weinberg (TW) method in measuring the pattern speed of barred galaxies at high redshifts. Measuring pattern speeds at high redshift may help to shed light on the time evolution of interactions between galactic bars and dark matter halos. The TW method has been extensively employed for nearby

We present the discovery of 30 transiting giant planets that were initially detected using data from NASA's Transiting Exoplanet Survey Satellite mission. These new planets orbit relatively bright (G ≤ 12.5) FGK host stars with orbital periods between 1.6 and 8.2 days, and have radii between 0.9 and 1.7 Jupiter radii. We performed follow-up ground

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
