| Abstract: | X-ray astronomy satellite TENMA observed that the X-ray pulsation of Vela X-1 suddenly disappeared for tens of minutes. This phenomenon may be interpreted in terms of the eclipse by a planet of HD77581, the optical companion of Vela X-1. |
| Keywords: | X-ray binary X-ray pulsar Vela X-1 X-ray eclipse planet |
