Asteroseismology of solar-like oscillators provides unique insights into stellar evolution, from the main sequence through to advanced stages of the red giant phase. In this poster, we present a study of the binary fraction among red giants, from combined data from the APOKASC-3 and APO-K2 catalogs with the Gaia Non-Single-Star catalog. This large

We present and analyse the results of the Science Data Challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an epoch of reionization (EoR) foreground-removal exercise organized by the Square Kilometre Array Observatory (SKAO) on SKA simulated data. The challenge ran for 8 months, from 2023 March to October. Participants were provided

Context. We need to understand the spin evolution of massive stars to compute their internal rotation-induced mixing processes, isolate effects of close binary evolution, and predict the rotation rates of white dwarfs, neutron stars, and black holes. Aims. We discuss the spindown of massive main sequence stars imposed by stellar winds. Methods. We

The study presents a confirmation of six quadruples with two sets of eclipses that have the 2+2 architecture. These so-called doubly eclipsing systems still present a quite rare group of stars. We collected all available photometric data and carried out a detailed analysis of them. In addition to the precise TESS photometry used to model the light

Aims. We present analyses of six microlensing events: KMT-2023-BLG-0548, KMT-2023-BLG-0830, KMT-2023-BLG-0949, KMT-2024-BLG-1281, KMT-2024-BLG-2059, and KMT-2024-BLG-2242. These were identified in KMTNet data from the 2023–2024 seasons, selected for exhibiting anomalies shorter than one day – potential signatures of low-mass planetary companions
