Tuiren (star)

 
 
Tuiren, also referred to as HAT-P-36, is a 12th magnitude G-type main-sequence star estimated to be approximately 1,034 light-years away from Earth in the constellation Canes Venatici. Tuiren is too faint to be seen with the naked eye, but it is possible to view it with binoculars or a small telescope. In 2012 a hot Jupiter-type exoplanet was discovered orbiting Tuiren with an orbital period of about 1.3 Earth days. In December 2019, HAT-P-36 was named Tuiren and its planetary companion, HAT-P-36b, was named Bran as a result of Ireland's contribution to the 2019 NameExoWorlds campaign. Bran has a mass approximately 1.8 times that of Jupiter and a radius 1.2 times larger.
Etymology.
Tuiren and its planet are named after characters from "The Birth of Bran", a story in the book "Irish Fairy Tales" by James Stephens. The book is a re-telling of various stories from Irish folklore. Tuiren was the aunt of the mythical hero Fionn mac Cumhaill and was turned into a hound by the fairy Uchtdealbh after Tuiren married her husband. Bran and Sceólan were the two puppies mothered by Tuiren while she was a dog. They were cousins of Fionn mac Cumhaill. The names were proposed by John Murphy, a teacher at Regina Mundi College, Cork.
Planets.
Bran (HAT-P-36b) was discovered in 2012 by the HATNet Project using the transit method.
