Description
We present preliminary results from an ongoing study of the bulges of S0 galaxies. We show that in a subsample of 14 barred S0 galaxies, fully half the photometrically defined bulges show kinematic signatures of "pseudobulges" -- that is, their kinematics are dominated by rotation. In four of these galaxies, we identify at least two subcomponents in the photometric bulge region: flatter, disk or bar components, assocated with disklike kinematics; and rounder "inner bulges,'' which appear to be hotter systems more like classical bulges.

    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
