“Kappa Pictoris”的意思、由来-开放百科全书

This is a B-type main sequence star with a stellar classification of B8/9 V.^[4] It is about 76.4% of the way through its main sequence lifespan.^[11] The star is spinning rapidly with a projected rotational velocity of 264 km/s.^[11] It has an estimated 3.4 times the mass of the Sun and is radiating 210 times the Sun's luminosity from its photosphere at an effective temperature of 11,641 K.^[11]

It is close to the lower limit of stars that are visible to the naked eye having an apparent visual magnitude of +6.11.^[3] Based upon an annual parallax shift of 5.14 mas as seen from Earth, this star is located around 630 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.10 due to interstellar dust.^[10] This is a B-type main sequence star with a stellar classification of B8/9 V.^[4] It is about 76.4% of the way through its main sequence lifespan.^[11] The star is spinning rapidly with a projected rotational velocity of 264 km/s.^[11] It has an estimated 3.4 times the mass of the Sun and is radiating 210 times the Sun's luminosity from its photosphere at an effective temperature of 11,641 K.^[11] References 1. ^¹²{{citation \| title=Spatial distribution and kinematics of OB stars \| last1=Gontcharov \| first1=G.
