Vela X is a strong radio pulsar source, that is also associated with a very strong 100 MeV gamma-ray source, and the rather weak Uhuru X-ray source 4U 0833-45. It is isolated, and should not be confused with the very different strong accreting, pulsing, eclipsing binary X-ray source Vela X-1, also known as 4U 0900-40, and which is associated with the supergiant star HD 77581. Both objects are of high intrinsic interest, and extensively studied.
