Beta Lyrae is a complex star studied since 1830 and has been the subject of more than 850 publications. The coordination of photometric, spectroscopic and interferometric observations (NPOI, CHARA / MIRC and VEGA) made it possible to set up a first article (Mourard et al., 2018, arXiv: 1807.04789) which provides a global model reproducing at the same time all photometric (i.e. from UDV domain to infrared) observations, as well as interferometric data (code SHELLSPEC). This analysis provides a consistent understanding of the object, whose figure above gives a representation.
