TY Pyxidis is an eclipsing binary star in the constellation Pyxis. The apparent magnitude ranges from 6.85 to 7.5 over 3.2 days.[1]
The two components are both of spectral type G5IV, have a mass of 1.2 solar masses and revolve around each other every 3.2 days.[2] Each star is around 2.2 times the diameter of the Sun.
The system is classified as either a RS Canum Venaticorum variable[1] or a BY Draconis variable, stars that vary on account of prominent starspot activity, and lies 184 ± 5 light years away. The system emits X-rays, and analysing the emission curve over time led Pres and colleagues to conclude that there was a loop of material arcing between the two stars.[3]
