In this paper, we present a combined photometric, spectroscopic, and orbital period study of three early-type eclipsing binary systems: XZ Aql, UX Her, and AT Peg. As a result, we have derived the absolute parameters of their components and, on that basis, we discuss their evolutionary states.

      Astronomers have performed a photometric and spectroscopic monitoring campaign of the star-forming region NGC As a result, they found that this region hosts a . temperatures Eclipsing binary system could also be spectroscopic or astrometric system at the same time if we can see eclipses. binary studies involve combination of photometric and spectroscopic data.

Abstract: A preliminary analysis of spectroscopic, photometric and interferometric observations of the triple subsystem of a hierarchical quadruple system xi Tau is presented. The triple system consists of a close eclipsing binary (P^{A} = 7fd), revolving around a common centre of gravity with a distant tertiary (P^{B} = &d).

Based on new, multicolour photometric light curves and spectroscopically determined mass ratio values, we derived accurate physical parameters of the components.

1. Introduction. WW And (V = mag, B − V = ±A5+F3p) is a long period (P orb ≈ d), Algol-type binary first spectroscopic data obtained in the blue part of the spectrum at orbital phases close to the primary minimum revealed red emission components in hydrogen and the Ca II K absorption lines (Wyse,Struve, ), and suggested the existence of H α and.

parameters are used to test evolutionary models, and systems showing apsidal motion can also be used to test the model’s internal structure predictions. For this purpose, we present a photometric and spectroscopic analysis of the eclipsing binary BW Aquarii, an evolved F-type binary with slow apsidal motion.

We model the K2 C3 light curve. 1. Introduction. The photometric variation of V Ser (HD; SAO; GSC ; P = 3 d, V max = 7 m, Sp.A0) was found using the TYCHO instrument of the Hipparcos satellite (Makarov et al., ).

Bastian and Born () classified V Ser as an Algol type binary system with a period of ± days. This classification was determined using Born’s visual. Abstract. A number of papers presented in the past few days at our Conference have dealt — directly or indirectly — with spectroscopic phenomena observed in close binary systems which cannot be ascribed to any one of the two constituting components; and whose origin must, therefore, be sought outside the simple gravitational dipole represented by these stars.

This book provides a comprehensive account of present knowledge concerning the theory of dynamical phenomena exhibited by close binary systems and outlines probable evolutionary trends of such.

Photometric and Spectroscopic Binary Systems | Our conference - opening today - has two aims in view: first, to commemorate some milestones in the development of the studies of close binary systems whose anniversaries fall in these years, as well as to take stock of our present knowledge accumulated through- out preceding decades, in order to consider where do we go from here.

Scientific Affairs Division.;]. first photometric spectroscopic solution for this system was obtained by using the latest version of the Wilson-Devinney program. The orbital inclination of () confirms that this system is a total eclipsing binary system.

Our solution indicates that EZ Hya is W-type overcontact binary with a small mass ratio of q p. A binary star is a star system consisting of two stars orbiting around their common s of two or more stars are called multiple star systems, especially when more distant, often appear to the unaided eye as a single point of light.

However, the recent realization that BD+20 is a short period, double-line, spectroscopic binary whose components have very different lithium abundances, vitiates standard methods of age determination.

We find the system to be metal-poor; this, combined with its measured lithium abundances, indicates that BD+20 may be several to many Gyr.

At least the brighter member of such a binary can be seen to have a continuously changing periodic velocity that alters the wavelengths of its spectral lines in a rhythmic way; the velocity.Spectroscopic and photometric analysis of three detached binary systems: AP And, VZ Cep and V Per S.
