With some 15, 15 and 30 years of MDI, HMI and GONG observations, respectively, we have reached a new milestone in acquiring almost three decades of nearly continuous helioseismic observations. Moreover, an alternative fitting methodology for global helioseismology to the respective projects' pipeline has produced tables of individual mode

The Sextans dwarf spheroidal galaxy has been challenging to study in a comprehensive way as it is highly extended on the sky, with an uncertain but large tidal radius of between 80–160 arcminutes (or 3–4 kpc), and an extremely low central surface brightness of ∑ V ∼ 26.2 mag/arcsec 2. Here, we present a new homogeneous survey of 41 VLT/FLAMES multi

The infrared excess shown by white dwarfs can be an indicator of a low-mass substellar companion, like a brown dwarf or even an exoplanet. In this work, we describe the methodology followed to identify white dwarfs with infrared excess within 100 pc and we show the preliminary results. Our initial sample is an almost complete volume-limited white

Identifying new white dwarfs (WDs) heavy elements is crucial, as they serve as valuable tools for deducing the chemical characteristics of potential planetary systems accreting material onto their surfaces. To detect metallic WDs, we propose a methodology based on an unsupervised learning technique known as Self-Organizing Maps (SOM). This approach

The WEAVE-Apertif survey combines spatially resolved optical and HI spectroscopic observations to investigate galaxy evolution using a representative sample of 400 gas-rich galaxies. Utilizing the WEAVE large integral-field unit (LIFU) at the William Herschel Telescope (WHT) and the upgraded Apertif system at the Westerbork Synthesis Radio

The MONOS project has obtained WEAVE LIFU observations to study the cores of nine stellar clusters containing O and B stars. Most O stars form in multiple systems, which allows for the determination of stellar masses through their orbits. However, this process is complicated by the wide range of orbital periods and the presence of complex systems
