Description
We present spectropolarimetric observations in the He I 1083.0 nm multiplet of a quiescent, hedgerow solar prominence. The data were taken with the Tenerife Infrared Polarimeter attached to the German Vacuum Tower Telescope at the Observatorio del Teide (Tenerife; Canary Islands; Spain). The observed He I circular and linear polarization signals are dominated by the Zeeman effect and by atomic level polarization and the Hanle effect, respectively. These observables are sensitive to the strength and orientation of the magnetic field vector at each spatial point of the field of view. We determine the magnetic field vector of the prominence by applying the HAZEL inversion code to the observed Stokes profiles. We briefly discuss the retrieved magnetic field vector configuration.

    Accretion-induced variability of interacting red giant binaries masquerading as oscillations
    Symbiotic stars are strongly interacting binaries with long orbital periods, containing an evolved red giant and a white dwarf or a neutron star embedded in a circumbinary nebula. They constitute unique astrophysical laboratories important for understanding the binary evolution and diverse processes occurring also in many other types of

    2 Young 2 Furious - Challenges and opportunities in the study of young exoplanets
    Current theories of planetary evolution predict that infant giant planets have large radii and very low densities before they slowly contract to reach their final size after about several hundred million years. These theoretical expectations have remained untested for a long time, as the detection and characterization of very young planets is

    The mysterious globular cluster population of NGC5846-UDG1 (MATLAS-2019)
    The number of globular clusters plays a fundamental role in understanding the early stages of galaxy formation. We know that the GC population of normal galaxies correlates with the amount of dark matter in these objects. Extending this analysis to the number of globulars in very low surface brightness galaxies is therefore key to understanding the
