B-type subgiant star in the constellation Cygnus
Omega1 Cygni ,
Latinized from ω1 Cygni , is the
Bayer designation for a solitary
[14]
star in the northern
constellation of
Cygnus . It is visible to the naked eye with an
apparent visual magnitude of 4.94.
[5] Based upon an annual
parallax shift of 2.59
mas ,
[8] it is estimated to lie roughly 1,260
light years from the
Sun . Relative to its neighbors, this star has a
peculiar velocity of 25.7± 2.2 km/s .
[7]
This is a somewhat
evolved
B-type
subgiant star with a
stellar classification of B2.5 IV.
[4] Telting and colleagues report it as a
Beta Cephei variable with a high degree of confidence as they found regular pulsations in its
spectrum in a high-resolution spectroscopy study published in 2006.
[6] Its brightness varies irregularly by 0.034 magnitude every 1.137 days.
