Distributions of wide binary stars in theory and in Gaia data: III. Orbital momenta, masses, and manifestations of MOND

Valeri V. Makarov

Using the censored catalog of 103,169 resolved Gaia DR3 binary stars with accurate astrometric data for each component, a new observable, object-specific parameter is computed for…

Initial conditions for tidal synchronisation of a planet by its moon

Valeri V. Makarov, Michael Efroimsky

Moons tidally interact with their host planets and stars. A close moon is quickly synchronised by the planet, or becomes captured in a higher spin-orbit resonance. However, the pla…

Distributions of wide binary stars in theory and in Gaia data: II. Reconstruction of sample probability density of true orbit sizes

Valeri V. Makarov

Wide binary stars are important for testing alternative models of gravitation in the weak-field regime and understanding the statistical outcomes of dynamical interactions in the g…

Kinematic Distortions of the High-Redshift Universe as Seen from Quasar Proper Motions

Valeri V. Makarov

Advances in optical astrometry allow us to infer the non-radial kinematic structure of the Universe directly from observations. Here I use a supervised machine learning neural netw…

Orbital inclination of astrometric binaries and the dearth of face-on orbits in Gaia DR3 solutions

Valeri V. Makarov

The orbital solutions for astrometric (unresolved) binary stars provided in the Gaia mission Data Release 3 reveal an obvious deficit of face-on orbits with line-of-sight inclinati…

Distributions of wide binary stars in theory and in Gaia data: I. Generalized Ambartsumian (1937) approach and the family of power-law distributions of eccentricity

Valeri V. Makarov

The orbital parameter space of wide, weakly bound binary stars has been shaped by the still poorly known circumstances of their formation, as well as by subsequent dynamical evolut…
