cds-question@unistra.freclipsing-binary-starsspectroscopic-binary-starsradial-velocityvisible-astronomyspectroscopyBinaries play key roles in determining stellar parameters and exploring stellar evolution models. We build a catalog of 88 eclipsing binaries with spectroscopic information, taking advantage of observations from both the Large Sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST) and the Palomar Transient Factory (PTF) surveys. A software pipeline is constructed to identify binary candidates by examining their light curves. The orbital periods of binaries are derived from the Lomb-Scargle method. The key distinguishing features of eclipsing binaries are recognized by a new filter, Flat Test. We classify the eclipsing binaries by applying a Fourier analysis on the light curves. Among all the binary stars, 13 binaries are identified as eclipsing binaries for the first time. The catalog contains the following information: the position, primary eclipsing magnitude and time, eclipsing depth, the number of photometry and radial velocity observations, largest radial velocity difference, binary type, the effective temperature of the observable star Teff, and surface gravity of the observable star logg. The false-positive probability is calculated by using both a Monte Carlo simulation and real data from the Sloan Digital Sky Survey Stripe 82 Standard Catalog. The binaries in the catalog are mostly with a period of less than one day. The period distribution shows a 0.22 day cutoff, which is consistent with the low probability of an eclipsing binary rotating with such a period.2020ApJS..249...31Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/249/31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : SB9: 9th Catalog of Spectroscopic Binary Orbits (Pourbaix+ 2004-2014)B/gcvs : General Catalog of Variable Stars (Samus+, 2007-2017)V/153 : LAMOST DR4 catalogs (Luo+, 2018)J/A+AS/109/447 : Eclipsing binaries EROS catalogue (Grison+, 1995)J/AcA/48/563 : BVI phot. of OGLE SMC eclipsing binaries (Udalski+, 1998)J/AcA/54/1 : OGLE II SMC eclipsing binaries (Wyrzykowski+, 2004)J/ApJS/162/207 : Radial velocities of solar-type stars (Abt+, 2006)J/ApJ/652/313 : BV phot. of a detached EB in M33 (Bonanos+, 2006)J/AJ/134/973 : SDSS Stripe 82 star catalogs (Ivezic+, 2007)J/AJ/140/184 : RAVE double-lined spectroscopic binaries (Matijevic+, 2010)J/ApJS/190/1 : A survey of stellar families (Raghavan+, 2010)J/AJ/141/83 : Kepler Mission.
