  • Multiperiodicity in the Orbital Period Variations of the Eclipsing Binary System Z Per
    Astron. Rep. (IF 1.164) Pub Date : 2020-07-17
    A. I. Khaliullina

    Abstract The variations in the orbital period of the eclipsing binary system Z Per have been analyzed. It has been shown that the variations in the period can be represented as a superposition of the secular decrease in the period at a rate of 1.61 × 10–6 days/year and its three cyclic variations with periods of 22.6, 37.9, and 62.4 years. Z Per is most likely a quadruple system with periods of additional

    Abstract—For the case of the sub-Alfvén regime of the stellar wind flyby around the planet, the flow structure in the vicinity of a hot Jupiter have been studied by three-dimensional numerical simulation. As an example, the hot Jupiter HD 209458b was considered. The planet’s magnetic moment was set equal to 10% of the magnetic moment of Jupiter. The average magnetic field at the parent star’s surface

    Abstract—The distribution of young pulsars in the log(dP/dt)–log(tc) diagram that have a characteristic age tc < ~5 × 106 yr and a period derivative dP/dt > ~10–16 is analyzed. Six clusters-stripes are revealed for the first time, along which the long-term evolution tracks of individual pulsars pass.

    The variation of the orbital periods found in high-mass X-ray binaries occurring over time can be explained by two models. According to the first model, orbital decay occurs due to dynamic tidal forces. The second model shows that the change occurs due to the inertia moments of a massive star during its evolution. These models are applied to LMC X-4 and Cen X-3.
