Pi2 Columbae

π2 Columbae, Latinized as Pi2 Columbae, is a binary star system in the southern constellation of Columba, near the southern constellation border with Pictor. It is white-hued and dimly visible to the naked eye with a combined apparent visual magnitude of 5.50. Based upon an annual parallax shift of $31$ as seen from Earth, this system is located about 254 light years from the Sun. They are receding with a heliocentric radial velocity of +31 km/s.

The pair have an angular separation of 0.1 arc seconds with the primary being an A-type main-sequence star of spectral class A0 V, while the secondary component is a similar A-type star. The primary is 98 million years old with 2.6 times the mass of the Sun and is spinning rapidly with a projected rotational velocity of 274 km/s. It is radiating 31 times the luminosity of the Sun from its photosphere at an effective temperature of 11,223 K. The system is a source of X-ray emission with a luminosity of $11,223$, which is considered unusual since A-type stars are not expected to display magnetic activity.
