Double-lined eclipsing binaries
WebApr 6, 2024 · The binarity of G 68-34 confirms our hypothesis from Pass et al. (2024): in that work, we noted that G 68-34 was both rapidly rotating and old, highly unusual given our understanding of the spindown of M dwarfs, and that a close binary companion may be responsible. Submission history From: Emily Pass [ view email ] WebIf, in the spectrum of a star, two sets of spectral lines can be observed which oscillate in opposite directions, the star is called a double- lined spectroscopic binary. If only one set of lines is present, the star is called a single-lined spectroscopic binary.

WebEclipsing binaries are not as common as spectroscopic ones because of the way they are aligned with respect to the earth. Any binary star could produce eclipses if viewed from the proper direction which is the edge on view. However, from our vantage point on earth, only a few binary stars systems are oriented in this way.
