HD 33564 is a single[7] star with an exoplanetary companion in the northern constellation of Camelopardalis. It has an apparent visual magnitude of 5.08,[1] which means it is a 5th magnitude star that is faintly visible to the naked eye. The system is located at a distance of 68 light years from the Sun based on parallax, and it is drifting closer with a radial velocity of −11 km/s.[2] It is a candidate member of the Ursa Major Moving Group.[8]

Description

This is an ordinary F-type main-sequence star with a stellar classification of F7V,[3] indicating that the star is hotter and more massive than the Sun, giving it a yellow-white hue. The star is about two[5] billion years old and is chromospherically quiet,[9] with a projected rotational velocity of 14.3 km/s. It has about 1.5[6] times the radius and 1.3[5] times the mass of the Sun. The star is radiating 3.4 times the luminosity of the Sun from its photosphere at an effective temperature of 6,396 K.[5]

Planetary system

In September 2005, a massive planet was found on an eccentric orbit about the star, based on radial velocity variations measured by the ELODIE spectrograph. An infrared excess had been detected at a wavelength of 60 μm, suggesting the star may host a circumstellar disk. However, the existence of a disk is unlikely because the infrared radiation is coming from a background galaxy.[9]
