HD 47536 is a single[1] star in the southern constellation of Canis Major. It has an orange hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.25.[2] The star is located at a distance of approximately 408 light years from the Sun based on parallax. It is drifting further away with a radial velocity of 80 km/s.[3]

This is an aging, metal-poor giant star with a stellar classification of K1 III.[4] It is about 9.3 billion years old with 94% of the mass of the Sun. Having exhausted the supply of hydrogen at its core, the star cooled and expanded to 23 times the Sun's radius.[5] The star is spinning slowly, taking Шаблон:Convert to complete its sidereal rotation. It is radiating 177[5] times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,384 K.[5] As of 2015, at least one planet is known to orbit this star.[6]

Planetary system

A planetary companion to this star, HD 47536 b, was discovered in 2003 by a team led by J. Setiawan.[7][8] A second planet, HD 47536 c, was claimed in 2007.[9] However, a follow-up study by Soto et al. in 2015 failed to detect the signal of the second planet, so it remains unconfirmed.[6]
