MUSE reveals different gas components in planetary nebulae
We present a detailed study of the gas chemical abundances in planetary nebulae (PNe), the final fate of solar-like stars, through high spatial resolution...
Neural networks to distinguish real and simulated galaxies
Can neural networks distinguish computer simulated galaxy images from observed galaxies? This is the question that has been addressed in this work. For years...
New insights into the puzzle of strong CO absorptions in massive early-type galaxies
Puzzling properties of massive early-type galaxies (ETGs) emerge when studying their spectra at near-infrared (NIR) wavelengths. Massive ETGs show strong CO...
Nightside condensation of iron in an ultrahot giant exoplanet
Ultrahot giant exoplanets receive thousands of times Earth’s insolation. Their high-temperature atmospheres (greater than 2,000 kelvin) are ideal laboratories...
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...
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...
