Context. One of the primary goals of Galactic Archaeology is to reconstruct the Milky Way's accretion history. To achieve this, significant efforts have been dedicated to identifying signatures of past accretion events. In particular, the study of the integrals of motion (IoM) space has proven to be highly insightful for uncovering these ancient

Highly irradiated giant exoplanets known `ultrahot Jupiters' are anticipated to exhibit large variations of atmospheric temperature and chemistry as a function of longitude, latitude and altitude. Previous observations have hinted at these variations, but the existing data have been fundamentally restricted to probing hemisphere-integrated spectra

Context. While many hot Jupiter systems have an obliquity measurement, the data on warm Jupiter systems are lacking. The longer orbital periods and transit durations of warm Jupiters make it more difficult to measure the obliquities of their host stars. However, the longer periods also mean that any misalignments persist due to the longer tidal

The Nuclear Spectroscopic Telescope Array (NuSTAR) enables detailed high-energy X-ray observations from 3─79 keV, but its performance can be constrained by telemetry saturation when observing bright sources, leading to reduced effective exposure times. In this study, we investigate the use of serendipitous stray light (SL) observations to infer

The measurements of pressure- and mixed-mode oscillation frequencies in subgiant stars offer a unique opportunity to probe their internal structures ─ from the surface to the deep interior ─ and to precisely determine their global properties. We have conducted a detailed asteroseismic analysis of the benchmark subgiant $\mu$ Herculis using eight

The polar mid-infrared (MIR) emission detected within tens to hundreds of parsecs in some active galactic nuclei (AGN) has been associated with dusty winds driven away by radiation pressure. The physical characterization of this extended polar emission remains uncertain. Here, we combine 10─21 μm JWST/Mid-InfRared Instrument (MIRI) imaging
