VizieR Online Data Catalog: SB2s in LAMOST-MRS (Kovalev+, 2024)
Abstract
We have used an updated method for the detection of SB2s using vsini values from spectral fits. The method is applied to all spectra from LAMOST-MRS. This method found 12426 (8105 new) SB2 candidates in the LAMOST-MRS. The updated method allows one to select many SB2 candidates, including ones with zero {DELTA}RV between components, if they have different spectra. We present a determination of the mass ratios and orbits for a subset of SB2 candidates with multiple observations.
Table B1 list of SB2 candidates with GaiaDR3 source_id, table C1 table with mass ratios and systemic velocities derived using Wilson method and table C2 derived circular and Keplerian orbits using GLS code (3 data files).- Publication:
