Searching for Accreting Compact Binary Systems from Spectroscopy and Photometry: Application to LAMOST Spectra.

ZHAO X., WANG S. and LIU J.

Abstract (from CDS):

Compact objects undergoing mass transfer exhibit significant (and double-peaked) Hα emission lines. Recently, new methods have been developed to identify black hole X-ray binaries and calculate their systematic parameters using Hα line parameters, such as the full width at half-maximum (FWHM), equivalent width (EW), and separation of double peaks. In addition, the FWHM-EW plane from spectroscopy and the Hα color-color diagram from photometry can be used for rapid stellar classification. We measure the Hα and Hβ profiles (e.g., FWHM and EW) using the LAMOST DR9 low- and medium-resolution spectra, and calculate the systematic parameters (e.g., velocity semiamplitude of the donor star, mass ratio, inclination angle, and mass of the accretor). A new correlation between FWHM and K2, K2 = 0.205(18) FWHM, is obtained for cataclysmic variables (CVs) in our sample. Both the FWHM-EW plane and the Hα color-color diagram can distinguish CVs with FWHM ≳ 1000 km s–1 from Be stars and young stellar objects to some extent. To improve classification accuracy and enhance the selection of compact objects, we propose a new set of idealized filters with effective widths of 30, 130, and 400 Å for the narrow Hα filter, broad Hα filter, and r-band filter, respectively.
