[edit] In science fiction

The star is mentioned in the Honorverse as the headquarters of Technodyne Industries of Yildun, a major Solarian League shipbuilding corporation with rather questionable ethics (e.g. business ties with Manpower Incorporated and Jessyk Combine, both of Mesa), though the star system is described as including only a (highly mineral-and-metals-rich) asteroid belt.
