Massive stars are known for their dramatic demise, commonly exploding as supernovae when their life cycle comes to an end. However, researchers have encountered a perplexing phenomenon: some massive stars seemingly vanish from the cosmos without a trace. Previously visible in earlier astronomical surveys, these stars are nowhere to be found in more recent observations. The question arises—what happens to these seemingly lost stars?
The most persuasive theory to date has been put forward by an international team led by astrophysicist Alejandro Vigna-Gómez. Their study points to the possibility that rather than going out with a bang, some massive stars may instead end their lives with a quiet collapse into a black hole. Evidence supporting this theory comes from the binary system VFTS 243 in the Large Magellanic Cloud, which comprises a black hole and its companion star and does not show evidence of the expected supernova explosion.

Vigna-Gómez explains the scenario of a star undergoing total collapse, which would result in it seeming to simply wink out of existence without the spectacle of a supernova. While direct observation of this phenomenon is rare, the study of VFTS 243 aligns with previous instances where bright stars have unexpectedly disappeared.
The more common supernova event entails a star’s outer layers being ejected into space, leaving behind a core that transforms into an extremely dense object—a neutron star or black hole. Nevertheless, the peculiar characteristics of the VFTS 243 system support the direct-collapse theory, providing compelling evidence for this alternative star death.
Researchers Irene Tamborra and others from the Niels Bohr Institute have recognized the significance of VFTS 243 as validating models of star collapse without supernovae, marking it as a critical reference for future research in this area. The detailed study has been published in Physical Review Letters.
FAQ Section
What happens to a star when it collapses without a supernova?
When a star collapses without a supernova, it undergoes a total collapse, resulting in the formation of a black hole. This process is quiet, devoid of the explosive supernova event, and might cause the star to simply vanish from the observable night sky.
How significant is the VFTS 243 system to this phenomenon?
VFTS 243 is currently the best observable case in support of the theory of stellar black holes formed through total collapse. Its study provides crucial evidence against the idea that all massive star deaths are marked by supernovae.
Can we see black holes directly?
No, black holes themselves cannot be seen directly because no light can escape from them. However, their existence can be inferred by observing the effect they have on surrounding matter, such as the orbital motion of a companion star.
Conclusion
The disappearance of massive stars without the occurrence of a supernova adds another layer of complexity to our understanding of stellar evolution. The binary system VFTS 243 offers invaluable insight into this quiet end of massive stars. As research continues, these findings are expected to play a pivotal role in shaping our knowledge about the life and death of stars, especially in cases where they escape detection by conventional methods. With the help of such research, the mysteries of the cosmos will gradually unravel, providing a clearer picture of the dynamics governing star collapse and the formation of black holes.
