The magnetic and kinematic configuration of sunspot penumbrae is investigated by performing an inversion of the Stokes profiles of three infrared lines at 1565...
Two new free-floating or wide-orbit planets from microlensing
Planet formation theories predict the existence of free-floating planets that have been ejected from their parent systems. Although they emit little or no light...
Two new SB2 binaries with main sequence B-type pulsators in the Kepler field
Context. OB stars are important in the chemistry and evolution of the Universe, but the sample of targets that is well understood from an asteroseismological...
Two spectral states of the transient X-ray burster SAX J1747.0-2853
The neutron star binary SAX J1747.0-2853, located in the Galactic Center region at about 0.5 deg from Sgr A* and at a distance of ˜9 kpc, has been observed in...
Aims: A transiting planet candidate with a sub-Neptune radius orbiting the nearby (d = 51.9 ± 0.07 pc) M1.5 V star TOI-1470 with a period of ~2.5 d was...
Two super-Earths at the edge of the habitable zone of the nearby M dwarf TOI-2095
The main scientific goal of TESS is to find planets smaller than Neptune around stars that are bright enough to allow for further characterization studies...
Context: We report on the first ultracool dwarf discoveries from the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey Early Data Release (LAS EDR), in...
Two temperate Earth-mass planets orbiting the nearby star GJ 1002
We report the discovery and characterisation of two Earth-mass planets orbiting in the habitable zone of the nearby M-dwarf GJ 1002 based on the analysis of the...
Two temperate super-Earths transiting a nearby late-type M dwarf
Context. In the age of JWST, temperate terrestrial exoplanets transiting nearby late-type M dwarfs provide unique opportunities for characterising their...
