Analysis of a δ Scuti spectroscopic binary: CQ Lyncis.
CARRIER F., DEBERNARDI Y., UDRY S., CARQUILLAT J.-M. and GINESTET N.
Abstract (from CDS):
CQ Lyn is a new double-lined spectroscopic binary, composed of an Am δ Scuti and a solar-like star, with an orbital period of 12.50736d and a zero-eccentricity. Physical parameters of both stars are well constrained. The characteristics of the primary are the following: M=1.714M☉, Teff=6760K, logL/L☉=1.097 and logg=3.85dex. Power spectra of Hipparcos photometry and Coravel radial velocities show multi-period pulsation behaviour. Three frequencies are identified: f1=8.86725, f2=8.81150 and f3=8.91007c/d and are assumed to be l=2 f-modes split by rotation, considering their pulsation constants Q1=0.0356, Q2=0.0359 and Q3=0.0355d. Two combination oscillations are also present in the power spectrum at frequency f1+f2 and f2+f3.
(Ref) Object type as listed in the reference "Ref"
(acronym) Object type linked to the acronym according to the original reference
() Anterior to 2007, before we can link the objet type to a reference, or given by the CDS team in some particular cases
Syntax of coordinates is : "ra dec (wtype) [error ellipse] quality bibcode" :
ra dec : right ascension and declination (unit and frame defined according to your Output Options)
Grey values are increasing the original precision due to the computation of frame transformations
(wtype) : wavelength class for the origin of the coordinates (Rad, mm, IR, Optical, UV, Xray, Gam)
[error ellipse] : measurement uncertainty, on (ra,dec) if the positional angle is 90 degrees, on (majaxis,minaxis) otherwise (in mas at defined epoch in the original catalogue),
position angle (in degrees North celestial pole to East)

[error] : error of the corresponding value displayed before
(wavelength) : wavelength range of the measurement : Rad, mm, IR, Opt, UV, Xray, Gam or '∼'(unknown)
quality : flag of quality ( A=best quality -> E=worst quality, ∼=unknown quality)
