    Polarimetry of Li-rich giants
    Context: .Protoplanetary nebulae typically present non-spherical envelopes. The origin of such geometry is still controversial. There are indications that it...

    Polarisation of very-low-mass stars and brown dwarfs. I. VLT/FORS1 optical observations of field ultra-cool dwarfs
    Context: Ultra-cool dwarfs of the L spectral type (T_eff = 1400-2200 K) are known to have dusty atmospheres. Asymmetries of the dwarf surface may arise from...

    Polarization echoes from past nuclear activity in the quasi-periodic eruption source GSN 069
    Context. X-ray quasi-periodic eruptions (QPEs) are repeating, high-amplitude, soft X-ray bursts observed from the nuclei of a dozen nearby low-mass galaxies...

    Polarization of changing-look quasars
    If the disappearance of the broad emission lines observed in changing-look quasars originates from the obscuration of the quasar core by dusty clouds moving in...

    Polarization of the changing-look quasar J1011+5442
    If the disappearance of the broad emission lines observed in changing-look quasars were caused by the obscuration of the quasar core through moving dust clouds...

    Polarized, variable radio emission from the scallop-shell binary system DG CVn
    DG CVn is an eruptive variable star and represents the closest member of the known sample of complex periodic variables, or scallop-shell stars. Over the years...

    Populations of evolved massive binary stars in the Small Magellanic Cloud: I. Predictions from detailed evolution models
    Context. The majority of massive stars are born with a close binary companion. How this affects their evolution and fate is still largely uncertain, especially...

    Populations of evolved massive binary stars in the Small Magellanic Cloud: II. Predictions from rapid binary evolution
    Context. Massive star evolution plays a crucial role in astrophysics; however, its study is subject to large uncertainties. This problem becomes more severe by...
