Test of binary spectral model on FEROS spectra. First estimation of the fundamental parameters for HD 20784
Mikhail Kovalev, Sarah Gebruers, Ilya Straumit
We analyse spectra of 26 early-type stars, with suspected binarity, using a binary spectral model adapted for high-resolution FEROS spectra. We confirm seven SB2 candidates (AE Pic…
Fundamental parameters for dEB SB2 binary system J064726.39+223431.6
Mikhail Kovalev, Song Wang, Xuefei Chen +1
We present a study of eclipsing binary J064726.39+223431.6 using spectra from the LAMOST-MRS and TESS photometry. We use full-spectrum fitting to derive radial velocities and spect…
Detection of 2460 SB2 candidates in the LAMOST-MRS, using projected rotational velocities and a binary spectral model
Mikhail Kovalev, Chen Xuefei, Han Zhanwen
We present a new method for the detection of double-lined spectroscopic binaries (SB2) using values from spectral fits. The method is tested on synthetic and real spectr…
TYC~2990-127-1: an Algol-type SB2 binary system of subgiant and red giant with a probable ongoing mass-transfer
Mikhail Kovalev, Zhenwei Li, Xiaobin Zhang +3
We present a study of the spectroscopic binary TYC 2990-127-1 from the LAMOST survey. We use full-spectrum fitting to derive radial velocities and spectral parameters. The high mas…
