49 Ceti

This is a young A-type main-sequence star with a stellar classification of A1V. It is about 40 million years old with a high rate of spin, showing a projected rotational velocity of 196 km/s. The star has double the mass of the Sun. It is radiating 19 times the Sun's luminosity from its photosphere at an effective temperature of 8,790 K.

49 Ceti displays a significant infrared excess, which is a characteristic of a debris disk orbiting the star. Unusually, the disk seems to be gas-rich, with evidence of carbon monoxide (CO) gas. This carbon monoxide gas may possibly be from comets orbiting the star within the disk, similar to the Kuiper Belt in the Solar System.
