This is a
main sequenceBe star with a
stellar classification of B3 Ve.[4] Samus et al. (2017) classify it as a Be variable, rather than a
Gamma Cassiopeiae type, and it ranges from a peak Hipparcos magnitude of 5.10 down to 5.22.[6] The star is spinning with a
projected rotational velocity of 95 km/s,[7] but is being viewed from an extreme pole-on position. Hence it is spinning much more rapidly than indicated. Outbursts of hydrogen
emission lines have been observed, as well as rapid changes in hydrogen line profiles.[12] It is 25[9] million years old with around six[7] times the
mass of the Sun.
