    Orbital parameters of the microquasar LS I +61 303
    New optical spectroscopy of the high-mass X-ray binary microquasar LS I +61 303 is presented. Eccentric orbital fits to our radial velocity measurements yield...

    Orbital parameters, masses and distance to β Centauri determined with the Sydney University Stellar Interferometer and high-resolution spectroscopy
    The bright southern binary star β Centauri (HR5267) has been observed with the Sydney University Stellar Interferometer (SUSI) and spectroscopically with the...

    Orbital periods of cataclysmic variables identified by the SDSS - III. Time-series photometry obtained during the 2004/5 International Time Project on La Palma
    We present time-resolved CCD photometry of 15 cataclysmic variables (CVs) identified by the Sloan Digital Sky Survey (SDSS). The data were obtained as part of...

    Orientation of planetary nebulae within the Galaxy
    Narrow-band CCD images of 209 axially symmetrical planetary nebulae (PNe) have been examined in order to determine the orientation of their axes within the disc...

    Origin of E+A galaxies - I. Physical properties of E+A galaxies formed from galaxy merging and interaction
    We investigate the structural, kinematical and spectrophotometric properties of `E+A' galaxies - those with strong Balmer absorption lines but no significant...

    Origin of stellar prolate rotation in a cosmologically simulated faint dwarf galaxy
    Stellar prolate rotation in dwarf galaxies is rather uncommon, with only two known galaxies in the Local Group showing such feature (Phoenix and And II)...

    Orphan optical flare as SOSS emission afterglow, localization in time
    We report on MASTER optical observations of an afterglow-like optical and X-ray transient AT2021lfa/ZTF21aayokph. We detected the initial steady brightening of...

    Oscillating red giants in eclipsing binary systems: empirical reference value for asteroseismic scaling relation
    The internal structures and properties of oscillating red-giant stars can be accurately inferred through their global oscillation modes (asteroseismology)...

    Outburst activity in comets - II. A multiband photometric monitoring of comet 29P/Schwassmann-Wachmann 1
    We have carried out a continuous multiband photometric monitoring of the nuclear activity of comet 29P/Schwassmann-Wachmann 1 from 2008 to 2010. Our main aim...
