Radio-Optical Reference Catalog, version 1

Valeri V. Makarov, Megan C. Johnson, Nathan J. Secrest

The fundamental celestial reference frame (CRF) is based on two catalogs of astrometric positions, the third realization of the International Celestial Reference Frame (ICRF3), and…

Pathways of Survival of Exomoons and Inner Exoplanets

Valeri V. Makarov, Michael Efroimsky

It is conceivable that a few thousand confirmed exoplanets initially harboured satellites similar to the moons of the Solar system or larger. Could some of them have survived over…

A catalog of candidate double and lensed quasars from Gaia and WISE data

Valeri V. Makarov, Nathan J. Secrest

Making use of strong correlations between closely separated multiple or double sources and photometric and astrometric metadata in Gaia EDR3, we generate a catalog of candidate dou…

Differential proper motion spin of the Hipparcos and Gaia celestial reference frames

Valeri V. Makarov

The Hipparcos catalog provides the first epoch of the celestial reference frame (CRF) in the optical domain and serves as an indispensable tool to verify and improve the Gaia CRF f…

The Hipparcos Pleiades parallax error is also a proper motion error

Valeri V. Makarov

The mean parallax of the Pleiades open cluster from the Hipparcos catalog is larger than the true value by approximately 1 mas. The origin of this error, as well as a possible algo…

Optical variability of ICRF3 quasars in the Pan-STARRS 3Pi survey with functional principal components analysis

C. T. Berghea, V. V. Makarov, K. Quigley +1

We make use of individual (epoch) detection data from the Pan-STARRS 3Pi survey for 2863 optical ICRF3 counterparts in the five wavelength bands g, r, i, z, and y, published as par…
