The overall pulsation amplitude of γ Doradus (GDOR) stars is not very actively studied. Paunzen et al. (2020) identified 15 high-amplitude GDOR (HAGDOR) stars, i.e., whose peak-to-peak light variation in the Johnson V band exceeds 0.1 mag. Based on this set and on a similarly small control sample, Paunzen et al. concluded that HAGDOR pulsators...

From current statistics, based on magnitude-limited samples, ~35% of sdO/B hot subdwarfs are in close binaries with M-dwarf/WD companions, ~30% are in wide binaries with FGK MS stars, and ~35% are apparently single. However, without a companion it is hard to explain the huge mass loss near the RGB tip needed to form an sdB star. The presence of...

Massive stars exhibit a perplexing mismatch between their inferred masses from different observational techniques, posing a significant challenge to our understanding of stellar evolution and structure. This discrepancy is believed to be caused by the underestimation of the convective core masses. The efficiency of such measurement is usually...

Getting confidential computing right is a tough challenge. Other architectures already tried in the past to introduce mechanisms for providing confidentiality guarantees, and in many cases failed. On RISC-V the Confidential Computing SIG, under the Security HC, is working on two specifications for providing confidentiality guarantees for...

ESA's PLATO space project stands for PLAnetary Transits and Oscillations of stars. The nominal mission has a 4-year duration, with an extension option of up to 8 years of operations. PLATO's launch is scheduled for December 2026 and after its cruise to L2 and the commissioning, its 26 telescopes will stare for a minimum of 2 years at its...

The RISER project aims to build accelerator and microserver systems based on RISC-V SoCs from ongoing European projects funded by the EuroHPC JU. Working with experimental hardware platforms requires substantial effort on verification and bring-up, including bare-metal tests aimed at the core, memory, and platform levels. Booting a full-blown...

This year's theme at ISC is "Reinventing HPC", with particular emphasis onintegrating AI-driven applications and quantum computing. Among otherchallenges, this broader scope of high-performance computing points to theneed to evolve the systems software infrastructure. This talk provides a systems software architect's perspective on engineering...

Products of stellar mergers are likely common in stellar populations and can potentially explain stars with peculiar properties. Massive post-main-sequence (post-MS) stellar merger products may remain on the blue side of the Hertzsprung gap (HG) for millions of years and, hence, provide a natural explanation for the overabundance of observed...
