Habitability of exoplanets orbiting flaring stars
Rebecca Szabó, Valentin D. Ivanov, M. Švanda
As of late 2025 there are about 70 exoplanets that meet the formal criterion of having equilibrium temperatures allowing the presence of liquid water and about 50 of them orbit M-s…
Archaeological investigation of galaxies' evolutionary history in the cosmic middle ages
Anna R. Gallazzi, Stefano Zibetti, Mark Sargent +14
The cosmic Middle Ages, spanning the last 8-10 Gyr of the Universe, is a critical period in which massive early-formed systems coexist with global star formation quenching in less…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites
C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48
A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
The Future of Evolved Planetary Systems
Roberto Raddi, Anna F. Pala, Alberto Rebassa-Mansergas +19
Understanding the formation, evolution, and chemical diversity of exoplanets are now central areas of astrophysics research. White dwarfs provide a uniquely sensitive laboratory fo…
Chemical complexity in star formation induced by stellar feedback: cores shock-formed by the supernova remnant W44
G. Cosentino, I. Jiménez-Serra, F. Fontani +8
Low-velocity shocks from Supernova Remnants (SNRs) may set the physical and chemical conditions of star formation in molecular clouds. Recent evidence suggests that the Sun might h…
On the Dusty Proximate Damped Lyman-α System toward Q2310-3358 at z = 2.40
S. Han, J. -K. Krogager, C. Ledoux +6
Quasar absorption systems not only affect the way quasars are selected, but also serve as key probes of galaxies, providing insight into their chemical evolution and interstellar m…
