As part of Saudi Arabia's Vision 2030 and under the guidance of the Royal Commission for AlUla (RCU), efforts are underway to establish AlUla Manara as the Kingdom's first major astronomical observatory. We present a preliminary assessment of the site based on European Centre for Medium-Range Weather Forecasts Fifth Generation Reanalysis data to

The morphology of circular polarization profiles from solar spectropolarimetric observations encodes information about the magnetic field strength, inclination, and line-of-sight velocity gradients. Previous studies used manual methods or unsupervised machine learning (ML) to classify the shapes of circular polarization profiles. We trained a

HD 138965 is a young A type star and member of the nearby young Argus association. This star is surrounded by a broad, bright debris disc with two temperature components that was spatially resolved at far-infrared wavelengths by Herschel. Here, we present Atacama Large Millimiter/Submillimeter Array (ALMA) millimetre-wavelength imaging of the cool

ALISIO-1, the first satellite owned and led by the Instituto de Astrofısica de Canarias (IAC), represents a significant milestone in the space exploration of the Canary Islands. This 6U CubeSat, whose platform has been developed by Open Cosmos, carries two novel payloads: DRAGO-2 and CubeLCT. DRAGO-2, a Short-Wavelength Infrared (SWIR) camera, is

Context. The study of resonant oscillation modes in low-mass red giant branch stars enables us to infer their ages with exceptional (∼10%) precision. This unlocks the possibility to reconstruct the temporal evolution of the Milky Way at early cosmic times. Ensuring the accuracy of such a precise age scale is a fundamental but difficult challenge

Planet formation models indicate that the formation of giant planets is substantially harder around low-mass stars due to the scaling of protoplanetary disc masses with stellar mass. The discovery of giant planets orbiting such low-mass stars thus imposes strong constraints on giant planet formation processes. Here we report the discovery of a
