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.

sedIcon
within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!).
