Description
In this work an analytical description of the NACO PSF with a minimum number of parameters is sought. These parameters are governed by the observational characteristics and the location of the PSF with respect to the guide star. The first order approximation of the PSF can then be used for image deconvolution. The analysis and modelling of the PSF was performed using images of a given position in the Galactic bulge collected in the Ks-band (2.00-2.36μm) with the S27 camera on 19/08 (seeing 1.1 arcsec) and 23/08/2002 (seeing 0.9 arcsec) during the science verification period of NACO.

    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
