T Antliae (also abbreviated T Ant) is a Cepheid variable star 2.3 kiloparsecs away from the Sun in the constellation of Antlia. A yellow-white supergiant with a spectral type of F6Iab, it ranges between apparent magnitude 8.88 and 9.82 over a period of 5.89820 days.
Stellar system
The F-type supergiant also forms a binary system with an unseen stellar companion with putative mass of 70% Solar mass. Such a stellar component could likely take 42.4 years to complete its orbit around the Cepheid (semimajor axis around 10.8 Astronomical Units).
