Advancing Astrophysics with the SKA II
Anna Bonaldi, Tyler L. Bourke, Philippa Hartley +45
Advancing Astrophysics with the SKA II (AASKAII), written by our science community, outlines the transformative scientific advances that will be enabled by the SKA telescopes. In t…
Exploring Activity Across the Stellar Main Sequence with the Sun as a Benchmark
Atul Mohan, Stephen M. White, Sven Wedemeyer +1
The active atmospheres of cool main-sequence stars (F-M type) often release a fraction of their stored magnetic energy, producing enhanced emissions (flares) across radio to X-ray…
The unique capabilities of HST for stellar physics: Probing Atmospheric Structure, Chromospheres, and Mass Loss of Evolved Stars
Maryam Saberi, Graham Harper, Jacco Th. van Loon +10
Evolved stars are among the primary sources of chemical enrichment and dust production in galaxies. During the giant phases, stars return a substantial fraction of their mass to th…
Stellar flare-driven evolution of primordial early exo-Earth atmospheres: Insights from a Young M Dwarf Flare model
E. Mamonova, K. Herbst, V. Kofman +4
Context. M dwarfs are key targets for terrestrial exoplanet studies, with prospects for atmospheric spectroscopy. However, strong stellar magnetic activity and frequent flaring req…
Young M dwarfs flare activity model: Towards better exoplanetary atmospheric characterisation
E. Mamonova, A. F. Kowalski, K. Herbst +2
Context. Stellar flares can significantly influence the atmospheres and habitability of orbiting exoplanets, especially around young and active M dwarfs. Understanding the temporal…
Fine details in solar flare ribbons: Statistical insights from observations with the Swedish 1-m Solar Telescope
Jonas Thoen Faber, Reetika Joshi, Luc Rouppe van der Voort +4
Flare ribbons serve as chromospheric footprints of energy deposition resulting from particle acceleration during magnetic reconnection. Their fine-scale structure provides a valuab…
