    First stellar spectroscopy in Leo P
    We present the first stellar spectroscopy in the low-luminosity (MV ˜ -9.3 mag), dwarf galaxy Leo P. Its significantly low oxygen abundance (3% solar) and...

    Five fake ultra-luminous X-ray sources
    Context. The nature of ultra-luminous X-ray (ULX) sources is still a matter of debate. Studies of their counterparts in other spectral ranges will help to...

    Five new eclipsing binaries with low-mass companions
    Precise space-based photometry from the Transiting Exoplanet Survey Satellite results in a huge number of exoplanetary candidates. However, the masses of these...

    Flare in the Galactic stellar outer disc detected in SDSS-SEGUE data
    Aims: We explore the outer Galactic disc up to a Galactocentric distance of ≈30 kpc to derive its parameters and measure the magnitude of its flare. Methods: We...

    Fluorescent Excitation of Balmer Lines in Gaseous Nebulae: Case D
    Nonionizing stellar continua are a potential source of photons for continuum pumping in the hydrogen Lyman transitions. In the environments where these...

    Forbidden hugs in pandemic times. I. Luminous red nova AT 2019zhd, a new merger in M 31
    We present the follow-up campaign of the luminous red nova (LRN) AT 2019zhd, the third event of this class observed in M 31. The object was followed by several...

    Forbidden hugs in pandemic times. II. The luminous red nova variety: AT 2020hat and AT 2020kog
    We present the results of our monitoring campaigns of the luminous red novae (LRNe) AT 2020hat in NGC 5068 and AT 2020kog in NGC 6106. The two objects were...

    Formation of Fullerenes in H-containing Planetary Nebulae
    Hydrogen depleted environments are considered an essential requirement for the formation of fullerenes. The recent detection of C60 and C70 fullerenes in what...

    Forty-four New and Known M-dwarf Multiples in the SDSS-III/APOGEE M-dwarf Ancillary Science Sample
    Binary stars make up a significant portion of all stellar systems. Consequently, an understanding of the bulk properties of binary stars is necessary for a full...
