An exoplanet with 13 times the mass of Jupiter - space short science news

Astronomers have discovered a giant exoplanet in the Cygnus constellation that has a mass 13 times that of Jupiter.

It is orbiting an old binary system, in which one star is dead (a white dwarf) and the other being a live star (i.e. magnetically active) with small mass (a red dwarf).

While most exoplanets have been observed in young binaries, consisting of two live stars, the current observations provide the first evidence for a similar organization in an old binary system.
