    Detection of the Irregular Shape of the Southern Limb of Menoetius from Observations of the 2017-2018 Patroclus-Menoetius Mutual Events
    This work presents the analysis of seven mutual events of the Patroclus-Menoetius system (PMS) observed during the last season of mutual events, in 2017-2018...

    Interactions between massive galaxies and their satellites: probing galaxy mass distribution.
    Using the measured common distance from the observer, angular separation of a dwarf satellite from its mother galaxy and their relative radial velocities, plus...

    On the outburst amplitude of the soft X-ray transients
    We find a strong correlation between the optical outburst amplitude and orbital period for the soft X-ray transient sources with orbital periods less than 1 d...

    Parameter estimates for the orbits of M 32 and NGC 205 about the centre of mass of the M 31 system
    The authors used simple kinematic, dynamic and geometrical assumptions to infer the orbital parameters of M32 and NGC 205 about M31. They find that both...

    Study of Some Dynamical Phenomena in the Solar System
    The number of minor bodies in the Solar System is continuing to increase. More than 30,000 asteroids have been discovered by 1996, and about 7,000 have been...

    The mass of the black hole in GS 2000+25 (=QZ Vul).
    The authors report the first infrared light curve of GS 2000+25. By modelling the brightness variations as ellipsoidal modulations of the secondary star, the...
