Periodicity in fast radio bursts due to forced precession by a fallback disk [PDF]
Research in Astronomy and Astrophysics, 2020 Recently, a 16-day periodicity in a fast radio burst was reported. We propose that this 16-day periodicity may be due to forced precession of the neutron star by a fallback disk.

Precession of timelike bound orbits in Kerr spacetime [PDF]
The European Physical Journal C, 2020 Astrometric observations of S-stars provide a unique opportunity to probe the nature of Sagittarius-A* (Sgr-A*). In view of this, it has become important to understand the nature and behavior of timelike bound trajectories of particles around a massive ...

Is OJ 287 a Single Supermassive Black Hole?
Universe, 2020 Light curves for more than century optical photometric observations of the blazar OJ 287 reveals strong flares with a quasi-period of about 12 years. For a long time, this period has been interpreted by processes in a binary black hole system. We propose

Prograde and retrograde precession of a fluid-filled cylinder
New Journal of Physics, 2021 We numerically study precession driven flows in a cylindrical container whose nutation angle varies between 60 and 90 degrees for prograde and retrograde precession.

INFLUENCE OF CONTROL CURRENT WAVEFORM ON ROTOR NUTATION OF THREE-DEGREES-OF-FREEDOM ELECTRIC MACHINE
Технічна електродинаміка, 2023 The design of the electric machine with three degrees of freedom of the rotor with an external magnetic core, containing permanent magnets, and an internal magnetic core is considered. The both magnetic cores are rotating.

Long-period nutational-precessional motions of the instantaneous Earth rotation pole
Учёные записки Казанского университета: Серия Физико-математические науки, 2020 The influence of the rotational regime on real long-period nutational-precessional motions of the instantaneous pole of the Earth’s rotation is considered. The solar magnetospheric (through changes in the angular velocity of rotation) mechanism of action

Precession Intuitively Explained
Frontiers in Physics, 2019 Formal explanations of the dynamics of free and heavy tops are considered to be known for centuries. However, intuitive understanding of their unexpected behavior is still a challenge.
