Period and period change measurements for 143 SuperWASP eclipsing binary candidates near the short-period limit and discovery of a doubly eclipsing quadruple system
Building on previous work, a new search of the SuperWASP archive was carried out to identify eclipsing binary systems near the shortperiod limit. 143 candidate objects were detected with orbital periods between 16 000 and 20 000 s, of which 97 are new discoveries. Period changes signif cant at 1σ or more were detected in 74 of these objects, and in 38 the changes were signif cant at 3σ or more....
متن کاملAO Velorum: a young quadruple system with a ZAMS eclipsing
Using recent spectroscopic observations, we show that the triple system AOVel with an eclipsing BpSi primary is in fact a remarkable quadruple system formed by two double-lined spectroscopic binaries with components close to the ZAMS. All available data have been reanalyzed to derive proper orbital parameters for both binary systems and to calculate absolute parameters of the eclipsing system. ...
متن کاملAbsolute dimensions of detached eclipsing binaries . I . The metallic - lined system WWAurigae
WWAurigae is a detached eclipsing binary composed of two metallic-lined A-type stars orbiting each other every 2.5 days. We have determined the masses and radii of both components to accuracies of 0.4% and 0.6%, respectively. From a cross-correlation analysis of high-resolution spectra we find masses of 1.964± 0.007M⊙ for the primary star and 1.814±0.007M⊙ for the secondary star. From an analys...
متن کاملCross - Correlation in Four Dimensions : Application to the Quadruple - Lined Spectroscopic System Hd 110555
We develop a technique to measure radial velocities of stars from spectra that present four sets of lines. The algorithm is an extension of the two-dimensional cross-correlation method TODCOR to four dimensions. It computes the correlation of the observed spectrum against a combination of four templates with all possible shifts, and allows also for the derivation of the light ratios of the comp...
متن کاملThe doubly eclipsing quintuple low - mass star system 1 SWASP J 093010 . 78 + 533859 . 5
Our discovery of 1SWASP J093010.78+533859.5 as a probable doubly eclipsing quadruple system, containing a contact binary with P ∼ 0.23 d and a detached binary with P ∼ 1.31 d, was announced in 2013. Subsequently, Koo and collaborators confirmed the detached binary spectroscopically, and identified a fifth set of static spectral lines at its location, corresponding to an additional noneclipsing ...
