Quasars with Proper Motions and the Link to Double and Multiple AGNs
Valeri V. Makarov, Nathan J. Secrest
Gaia used a large sample of photometrically selected active galactic nuclei (AGNs) and quasars to remove the residual spin of its global proper motion system in order to achieve a…
USNO Bright Star Catalog, version 1
Norbert Zacharias, Valeri V. Makarov, Charles T. Finch +3
USNO Bright Star Catalog (UBSC) is a new astrometric catalog of 1423 brightest stars covering the entire sky, which is published online. It is nearly complete to mag except f…
Chaos over Order: Mapping 3D Rotation of Triaxial Asteroids and Minor Planets
Valeri V. Makarov, Alexey Goldin, Alexei V. Tkachenko +2
Celestial bodies approximated with rigid triaxial ellipsoids in a two-body system can rotate chaotically due to the time-varying gravitational torque from the central mass. At smal…
Testing the Cosmological Principle: Astrometric Limits on Systemic Motion of Quasars at Different Cosmological Epochs
Valeri V. Makarov, Nathan J. Secrest
A sample of bona fide optical quasars with astrometric proper motions in Gaia EDR3 and spectroscopic redshifts above 0.5 in an oval 8400 square degree area of the sky is c…
The tidal quality of the hot Jupiter WASP-12b
Michael Efroimsky, Valeri V. Makarov
WASP-12b stands out among the planets of its class of hot Jupiters because of the observed fast orbital decay attributed to tidal dissipation. The measured rate of the orbital peri…
Astrometric mass ratios of 248 long-period binary stars resolved in Hipparcos and Gaia EDR3
Valeri V. Makarov, Claus Fabricius
Using the absolute astrometric positions and proper motions for common stars in the Hipparcos and Gaia catalogs separated by 24.75 years in the mean epoch, we compute mass ratios f…
