We present extensive follow-up time-series photometry of WD J0049‑2525, the most massive pulsating white dwarf currently known, with T eff = 13,020 K and log g = 9.34 cm s ‑2. The discovery observations detected only two significant pulsation modes. Here, we report the detection of 13 significant pulsation modes ranging from 170 to 258 s based on

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
