HD 131496 is an evolved subgiant star with an orbiting exoplanet in the constellation Boötes.
It is located at a distance of 432 light-years based on parallax measurements,[2] and is drifting further away with a heliocentric radial velocity of 1.4 km/s.
The winning proposal for the name of the star was Arcalís, after a mountain peak in northern Andorra where the Sun shines through a gap twice a year at fixed dates, leading to its use as a primitive Solar calendar.
The planet was named Madriu, after a glacial valley and river in southeastern Andorra that forms the major part of the Madriu-Perafita-Claror UNESCO World Heritage Site.
It has a mass at least 2.2 times that of Jupiter and is orbiting at a distance of 2.09 astronomical units (AU) once every 883 days.
