Application of the binary spectral model to high-resolution spectra. First estimation of the fundamental parameters for HD 20784.

Abstract (from CDS):

In this paper, we applied previously developed method of binary spectral model fitting to the high-resolution spectra of HD 20784. Simultaneously analysing all three available epochs, we found spectroscopic parameters for both components of the system. These parameters are consistent with stellar evolution model's predictions and analysis of the photometrical data from Transiting Exoplanets Survey Satellite (TESS).
