Orbits of 665 SB2s in Lamost-MRS
The period, mass ratio, eccentricity, and other orbital parameters are fundamental for investigating binary star evolution. However, the number of binaries with known orbital... -
New SB1s with sp. orbits from LAMOST DR8 LRS
The LAMOST Low-Resolution Spectroscopic (LAMOST-LRS) Survey provides radial velocities of 10 million stars. These observations can be used to identify new single-lined... -
Orbital parameters of Kepler heartbeat stars
Heartbeat stars (HBSs) are astrophysical laboratories for studying binaries with eccentric orbits. A catalog of 173 Kepler HBSs was reported by Kirk+ (2016, J/AJ/151/68), and we... -
3-D selection of 167 sub-stellar companions
We analyze 5108 AFGKM stars with at least five high-precision radial velocity points, as well as Gaia and Hipparcos astrometric data, utilizing a novel pipeline developed in... -
Galactic EB stars with eccentric orbits based on ETDs
A comprehensive catalog of 623 galactic eclipsing binary (EB) systems with eccentric orbits is presented with more than 2830 times of minima determined from the archived... -
Candidate mpc separation massive BH binaries
The role of mergers in the evolution of massive black holes is still unclear,and their dynamical evolution, from the formation of pairs to binaries and the final coalescence,... -
Properties of natural satellites
This service provides the physical and dynamical characteristics of natural satellites in the Solar System: size, mass, rotational properties, magnitude and albedo, orbital...
