Magnetized stars exhibit periodic variations of their longitudinal global magnetic fields, $B_e$, owing to rotation. Here, we present the second catalog of averaged stellar magnetic rotational phase curves and their parameters derived from a compilation of the published observational data and personal communications for 350 stars of various spectral types, which were published up to the end of December 2019. Magnetic Ap and Bp stars constitute the most numerous subset in the catalog (215 objects). Phase curves were obtained by fitting either a sinusoid or a double sine wave to series of the observed $B_e$ measurements using the least squares method. For some stars, we present magnetic phase curves derived from time series of the surface magnetic field, $B_s$, or obtained improved values of the rotational period, $P_{rm rot}$. We have also identified eight stars in our catalog that host planets or planetary systems.
The second version of the catalog contains information about 275 stars of different types. During the time that has elapsed since the creation of the first catalog, situation fundamentally changed primarily due to the significant increase of accuracy
We present a cross-calibration of Hipparcos and Gaia EDR3 intended to identify astrometrically accelerating stars and to fit orbits to stars with faint, massive companions. The resulting catalog, the EDR3 edition of the Hipparcos-Gaia Catalog of Acce
The number of known variable stars has increased by several magnitudes over the last decade, and automated classification routines are becoming increasingly important to cope with this development. Here we show that the upside-down CBH variables, whi
We present a catalog of stellar properties for a large sample of 6676 evolved stars with APOGEE spectroscopic parameters and textit{Kepler} asteroseismic data analyzed using five independent techniques. Our data includes evolutionary state, surface g
We have recently announced that the General Catalogue of Variable Stars enters the stage of its fifth, purely electronic edition (GCVS 5.1). Recently, we have incorporated a new, completely revised version for 1408 variable stars in the constellation
