Planetary system

In 2013, one superjovian planet (may be a brown dwarf),[3] named 2MASS J01225093−2439505 b, was discovered by direct imaging.[4] The measured planetary temperature is 1600Шаблон:± K,[5] and it exhibits an unusual, short-lived atmospheric dust type due to its relatively low surface gravity and young age.[4] The planetary spectrum is classified as L3.7Шаблон:±.[5] The planetary rotation axis is inclined to its orbit, obliquity is 33Шаблон:±°, while the orbit is well aligned with the equatorial plane of the star, misalignment is 1Шаблон:±°. The planet is rotating rapidly, with a period of 6.8Шаблон:± hours.[3]
