چکیده
ABSTRACT We have developed a new method for spectral analysis of binaries. Our successfully identifies double-lined spectroscopic binary (SB2) candidates from high-resolution Gaia-ESO spectra. Compared to the commonly used cross-correlation function analysis, it works binaries with rapidly rotating components. test our on synthetic and observational spectra BAFG stars vsin i 1 $330~\, {\rm km}\, s}^{-1}$ in open cluster M11. confirm five previously detected SB2 find 19 ones. For three candidates, we circular orbits obtain dynamical mass ratios.

Precision radial velocities of double - lined spectroscopic binaries with an iodine absorption cell
A spectroscopic technique employing an iodine absorption cell (I 2) to superimpose a reference spectrum onto a stellar spectrum is currently the most widely adopted approach to obtain precision radial velocities of solar-type stars. It has been used to detect ∼80 extrasolar planets out of ∼130 known. Yet in its original version, it only allows us to measure precise radial velocities of single s...
متن کاملHigh-precision Elements of Double-lined Spectroscopic Binaries from Combined Interferometry and Spectroscopy Application to the Β Cephei Star Β Centauri
We present methodology to derive high-precision estimates of the fundamental parameters of double-lined spectroscopic binaries. We apply the methods to the case study of the doublelined β Cephei star β Centauri. We also present a detailed analysis of β Centauri’s line-profile variations caused by its oscillations. High-resolution spectral time series and visual or interferometric data with a go...
متن کاملSpectroscopic binaries with elliptical orbits
The radial velocity curves of many spectroscopic binaries (SBs) are perturbed by gas streams or proximity effects. For SBs with circular orbits, these perturbations can give rise to spurious orbital eccentricities of high statistical significance. But tests to identify such anomalous orbits can be constructed since perturbed velocity curves are in general no longer Keplerian. The derived tests ...
متن کاملParenago 1540: A Pre-Main-Sequence Double-Lined Spectroscopic Binary Near the Orion Trapezium
Spectroscopic and photometric observations of the star Parenago 1540 (V = 11.3), located 10 arcmin west of the Trapezium in Orion, have shown the star to be a pre-main-sequence double-lined spectroscopic binary. Thirty-seven radial-velocity measurements were obtained from which the orbital elements of the binary were determined, in particular an orbital period P = 33.73 + 0.03 days and an eccen...
متن کاملStellar Astrophysics with a Dispersed Fourier Transform Spectrograph. I. Instrument Description and Orbits of Single-lined Spectroscopic Binaries
We have designed and constructed a second-generation version of the Dispersed Fourier Transform Spectrograph, or dFTS. This instrument combines a spectral interferometer with a dispersive spectrograph to provide high-accuracy, high-resolution optical spectra of stellar targets. The new version, dFTS2, is based upon the design of our prototype, with several modifications to improve the system th...
