Three stellar remnants formed when stars about the same size as the Sun shed their outer layers. Each remnant is a small, dense core.
| Remnant | Estimated age since the core formed | Surface temperature in K | Light output as a percentage of the Sun's light output |
|---|---|---|---|
| A | 10 million years | 25 000 | 5.0 |
| B | 1 billion years | 10 000 | 0.20 |
| C | 5 billion years | 5 000 | 0.01 |
A scientist predicts that the remnants will eventually become black dwarfs.
Explain how the data support the scientist's prediction.
