On the magnetic nature of quiet-Sun chromospheric grains
CaII Kgrains, i.e., intermittent, short-lived (about 1 minute), periodic (2-4 minutes), pointlike chromospheric brightenings, are considered to be the...
Origin of stellar prolate rotation in a cosmologically simulated faint dwarf
In the current cosmological model, galaxies are formed in a hierarchical way, by merging with each other. These mergers can lead to kinematic anomalies that can...
P-CORONA: A New Tool for Calculating the Intensity and Polarization of Coronal Lines in 3D Models of the Solar Corona
The solar corona—the outermost layer of the Sun’s atmosphere—is extremely hot and very low in density. One of the main challenges in solar physics is...
Photonic integrated circuits for astronomy: A formal description of an integrated photonics-based wavefront sensor (IP-WFS)
Solar wavefront sensing has been a challenge for astrophysical instrumentalists, due to the low contrast between the Sun and the sky background compared to...
Post-common envelope binaries as the precursors of extremely red old stars
Modelling dust formation in single stars evolving through the carbon-star stage of the asymptotic giant branch (AGB) (i.e., the late evolutionary stages of Sun...
Powerful winds driven by a supermassive black hole
The supermassive black holes in the centres of galaxies have a basic influence on their evolution. This happens during a phase in which the black hole is...
Proton acceleration in thermonuclear nova explosions revealed by gamma rays
Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf. Accumulation of hydrogen in a layer...
