A star within a star? We finally got to see this too: a Thorne–Żytkow object

Scishow space reports that a Thorne–Żytkow object had been discovered. It is a star within a star. Basically what we have here is a star that exploded into a supernova and a neutron star remained as a result. That neutron star was then engulfed by a red supergiant from the binary system they were in and so we have a star within a star. Not even sci-fi movies could have thought of that 😀

It is about HV 2112 in the Small Magellanic Cloud and the researchers were able to tell that it is about a Thorne–Żytkow object because such objects are theorized to have certain amounts of rubidium, lithium and molybdenum.

From EurekAlert:

Past research has shown that normal stellar processes can create each of these elements. But high abundances of all three of these at the temperatures typical of red supergiants is a unique signature of TŻOs.

The Universe gets increasingly overwhelming, that’s sure!
