    A Pulsar

    Explanation:

    Such white dwarf is a Pulsar (from pulsating star). Three main features we find in this kind of celestial body

    1. Incredibly high density, in a pulsar there is not what we can define as free interspace. Everything is mass

    2. - Huge rotational speed (more than hundreds of kilometer) spinning at more than hundreds of kilometer per second

    3.-Intense magnetic field

    Combinations of thse features make pulsar emits important amount of energies with pricese periods of time. And if on earth we look a jet of electromagnetic radiation with a precise rigurosity (at pricese period of time) is because we are looking a pulsar spinning and each time the radiation appears is a turn of the pulsar
