Its an F class yellow giant, that has burned up all of its hydrogen in the core and is now only burning hydrogen in an outer shell around a mostly helium core. In time, it will become a red super giant. Once it burns off it's various shell layers of fuel, it will expand into a planetary nebula, leaving behind a white dwarf at its core. The metal rich nebula will drift of into the cold dark interstellar gas and seed the material for the next generation of stars. Kind of like a nova, but a much more peaceful transition. The same fate awaits our own sun in 5 Billion years, when it is about 10 Billion years old.
Notice how much younger this star is when it began it's death rattle, only 6.2 Billion. This is very odd because if was older you would expect it to be hydrogen rich have a slightly slower evolution than our younger sun. But instead it is apparently metal rich (with no planets?) and is evolving much faster than our own sun despite being less massive?? Very strange.
