No pseudosynchronous rotation for terrestrial planets and moons
Valeri V. Makarov, Michael Efroimsky
We reexamine the popular belief that a telluric planet or satellite on an eccentric orbit can, outside a spin-orbit resonance, be captured in a quasi-static tidal equilibrium calle…
Tidal Friction and Tidal Lagging. Applicability Limitations of a Popular Formula for the Tidal Torque
Michael Efroimsky, Valeri V. Makarov
Tidal torques play a key role in rotational dynamics of celestial bodies. They govern these bodies' tidal despinning, and also participate in the subtle process of entrapment of th…
Dynamical evolution and spin-orbit resonances of potentially habitable exoplanets. The case of GJ 581d
Valeri V. Makarov, Ciprian Berghea, Michael Efroimsky
GJ 581d is a potentially habitable super-Earth in the multiple system of exoplanets orbiting a nearby M dwarf. We investigate this planet's long-term dynamics, with an emphasis on…
Revealing companions to nearby stars with astrometric acceleration
Andrei Tokovinin, Markus Hartung, Thomas L. Hayward +1
A subset of 51 Hipparcos astrometric binaries among FG dwarfs within 67pc has been surveyed with the NICI adaptive optics system at Gemini-S, directly resolving for the first time…
Quasometry, Its Use and Purpose
Valeri Makarov, Ciprian Berghea, David Boboltz +8
Quasometry is precision measurement of celestial positions and apparent motion of very distant extragalactic objects, such as quasars, galactic nuclei, and QSOs. We use this term t…
