T Centauri
variable star in the constellation Centaurus

T Centauri is a variable star located in the far southern constellation Centaurus. It varies between magnitudes 5.56 and 8.44 over 181.4 days, making it intermittently visible to the naked eye. Pulsating between spectral classes K0:e and M4II:e, it has been classed as a semiregular variable, though Sebastian Otero of the American Association of Variable Star Observers has noted its curve more aligned with RV Tauri variable stars and has classified it as one.
The variability of the star was discovered in 1894 by Ernest Elliott Markwick, and independently by Williamina Fleming in 1895.

Why this record matters
“T Centauri” is worth following because a concise public description often conceals a longer documentary argument. Here, Centauri, variable and star provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 28, 2026. The linked authority identifier is Q4181312. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1894 and 1895.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
