Thorne-Zytkow objects

Thorne–Żytkow objects

Red supergiants with neutron cores (first investigated by K. Thorne and A. Żytkow). Such objects are predicted to form either in the merger of a neutron star with a massive companion in a massive X-ray binary or in the collision of a neutron star with a low-mass star in a globular cluster. Although no Thorne–Żytkow has yet been identified, SS433 may be on the verge of becoming one. Thorne–żytkow objects are expected to lose their envelopes in strong stellar winds and to ultimately become single (possibly spun-up) pulsars.

Caption: Thorne-Zytkow Objects probably start out as binary stars, shown in this illustration.
This strange pair, called a Thorne-Zytkow Object, or TZO, was largely theoretical until now.
Thorne-Zytkow objects (TZOs) are hybrids of red supergiant and neutron stars that superficially resemble normal red supergiants, such as Betelguese in the constellation Orion.
