Long-period radio transients (LPTs) are periodic radio sources showing pulsed emission on time-scales from minutes to hours. The underlying sources behind this emission are currently unclear. There are two leading candidates: neutron stars or white dwarfs. Neutron stars could emit at LPT time-scales as magnetars, binaries, or precessing sources

Increasing space activities, especially in low-Earth orbits (LEO), lead to more orbital debris and night-sky pollution. Spectroscopic analysis of light reflected from artificial space objects can aid to identify dominant surface materials and their reflective properties. Satellites interact with sunlight in diffuse and specular reflections, which

Context. The analysis of the composition of primitive C-complex asteroids is essential to understand the distribution of volatiles in the Solar System since its formation. Primitive low-albedo families within the inner main asteroid belt are of particular interest because they are a significant source of carbonaceous near-Earth asteroids, such as

Hot Jupiters and their atmospheres are prime targets for transmission spectroscopy due to their extended atmospheres and the corresponding large signal-to-noise, providing the best possible constraints for the atmospheric carbon-to-oxygen (C/O) ratio and metallicity of exoplanets. Within BOWIE-ALIGN, we aim to compare JWST spectra of a sample of

Ultra-hot gas giants such as WASP-121b provide unique laboratories for exploring atmospheric chemistry and dynamics under extreme irradiation conditions. Uncovering their chemical composition and atmospheric circulation is critical for tracing planet formation pathways. Here, we present a comprehensive atmospheric characterisation of WASP-121b

Planetary radii are derived for 218 exoplanets orbiting 161 M dwarf stars. Stellar radii are based on an analysis of APOGEE high-resolution near-IR spectra for a subsample of the M dwarfs; these results are used to define a stellar radius-M K s calibration that is applied to the sample of M-dwarf planet hosts. The planetary radius distribution
