NotesA white star a little more than twice the mass and diameter of the Sun, with indications of the presence of a circumstellar disc of matter.

This small white star lies roughly 130 light years from the Sun. The Meridiana of its name seems to come from the fact that it lies just two degrees from the Galactic Meridian, in the direction of the centre of the galaxy.
