V1094 Tauri
Algol variable in the constellation Taurus
V1094 Tauri is a system of at least three stars in the constellation of Taurus. Two stars are resolved 21″ apart; the brighter is an eclipsing binary. In 2015, the parameters for the eclipsing pair were precisely measured. Radial velocity data also revealed apsidal motion with a period of 14,500±3,700 years, which may indicate a third star.
The star system was included in a 2003 study that featured GK Draconis and V1094 Tauri. The study suggested a mass of 1.10 M☉ for the primary star and a mass of 1.01 M☉ for the secondary. The two stars orbit each other at a distance of around 0.091 to 0.092 astronomical units and have an orbital period of around 9 days.
This brief starts where responsible research should: with the source description of “V1094 Tauri” as algol variable in the constellation Taurus. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as algol variable in the constellation Taurus. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q86957581. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015 and 2003.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
