The notation 'CN+1' indicates a higher than normal level of cyanogen (CN) absorption in the atmosphere of the star.
[20] Beta Columbae has a high proper motion across the celestial sphere[21] and is moving at an unusually large speed of 100 km s−1 relative to the Sun.
[10] About 107,200 years ago, it made a close approach to the Beta Pictoris system.
