We present a unique discovery of three new detected systems showing two different phenomena together. These are 2+2 quadruple stellar systems showing two eclipsing binaries as the inner pairs. And besides that, these systems were also found to exhibit the precession of the inner orbits causing the inclination changes manifesting themselves through

AM CVn systems are a subclass of cataclysmic variables where two DB WDs exchange H-depleted material under short period orbits -in the range approx. 5 - 65 minutes. The prototype, AM CVn (=HZ9) itself, was first discovered in 1957 as a "peculiar" DB WD by Greenstein & Matthews and in 1967 Smak found its characteristic 17-18 min photometric

In this work we made use of the lists of candidate members obtained by Gutiérrez Albarrán et al. (2024) for a target sample of 42 open clusters, ranging from 1 Myr to 5 Gyr and observed within the Gaia-ESO survey (GES), with the aim of studying Li as an age indicator and deriving an empirical Li-age relation for FGK late-type stars. We conducted a

Many detected planets experience hydrodynamic atmospheric escape during some stage of their life. Most of those exoplanets are hot Jupiters and sub-Neptunes orbiting close to their stars. Traditionally, the escape in these evaporating planets has been studied by Lyman-α line absorption measurements taken by instruments from space. Very recently, a

Context. The Spitzer Survey of Stellar Structure in Galaxies (S 4G), together with its Early Type Galaxy (ETG) extension, stands as the most extensive dataset of deep uniform mid-infrared (mid-IR; 3.6 and 4.5 μm) imaging for a sample of 2817 nearby (d < 40 Mpc) galaxies. However, the velocity criterion used to select the original sample results in

The Atacama Large Aperture Submillimetre Telescope (AtLAST) is a mature concept for the next generation 50-meter class single-dish astronomical observatory operating at submillimetre wavelengths, powered by renewable energy and run as a facility telescope by an international partnership. AtLAST will open a new discovery space in numerous fields of
