HATS-6

HATS-6, also known as MASS 05523523-1901539, lies at a distance of 484 light-years from Earth.

It is a 15th magnitude M-dwarf star, which is one of the most numerous types of stars in our Galaxy.

Although M-dwarfs are common, they are not well understood. Because they are cool they are also dim, for example, HATS-6 emits only 1/12th of the light of our Sun.

“We have found a small star, with a giant planet the size of Jupiter, orbiting very closely. It must have formed further out and migrated in, but our theories can’t explain how this happened,” said Dr George Zhou of the Australian National University, a co-author of a paper published in the Astronomical Journal (arXiv.org preprint).
