Using a European Southern Observatory in Chile, the astronomers have determined that the chemistry of the star and its alien planet is drastically different from the normal patterns of solar system development. Simply put, because so large of a planet is orbiting around such a chemically different star, astronomers are having to rethink their theories regarding planetary formation around stars. Because the star is at such an advanced age and astronomers can track its changes, they are also hoping to glean data that may provide insight into the relationship between stars and their orbiting planets, which may in turn reveal what our sun has in store for our solar system as it (the sun) grows with age.
“This is very exciting,” said study co-author Rainer Klement of the Max-Planck-Institut fur Astronomie (MPIA) in Heidelberg, Germany. For the first time, astronomers can finally study stars and planets from another galaxy because of the absorption of the Helmi Stream.
