A Neutron Star Collision Builds a Star Within a Star
A three-dimensional impact simulation followed by stellar evolution produced a bound Thorne-Żytkow object and a possible chemical signature.
Summary
A three-dimensional impact simulation followed by stellar evolution produced a bound Thorne-Żytkow object and a possible chemical signature.
The simulated neutron star settles inside a ten-solar-mass stellar envelope. Collision heating triggers broad nuclear burning before convection carries carbon-nitrogen-cycle material to the surface. The work connects formation and long-term evolution in simulation; it does not report an observed Thorne-Żytkow object.
Why it matters
A three-dimensional impact simulation followed by stellar evolution produced a bound Thorne-Żytkow object and a possible chemical signature.
