Recent observations of the potentially habitable planets TRAPPIST-1 e, f, and g suggest that
they possess large water mass fractions of possibly several tens of weight percent of water …

Following the discovery of a new class of X-ray variability seen in four galaxies, dubbed
quasi-periodic eruptions (QPEs), we reconsider the variability seen in the low-mass active …

Nominally anhydrous minerals in rocky planet mantles can sequester multiple Earth-oceans'
worth of water. Mantle water storage capacities therefore provide an important constraint on …

Context. A major goal in the search for extraterrestrial life is the detection of liquid water on
the surface of exoplanets. On terrestrial planets, volcanic outgassing is a significant source …

We investigate the physical nature of active galactic nuclei (AGNs) using machine learning
(ML) tools. We show that the redshift, $ z $, bolometric luminosity, $ L_ {\rm Bol} $, central …

Gamma-ray bursts and tidal disruption events are some of the most cataclysmic and
energetic events in the universe. Both result in highly luminous and complex emission …

This article deals with the most recent developments in the field of exoplanetary science
connecting the interior of the planets with their habitability. In this issue, I have specified the …
