A double system has a hidden verification. An atarac or pulsar is a neutron star that emits electromagnetic radiation from its magnetic poles, is highly magnetized, and rotates. These objects become very useful tools for astronomers due to their extremely regular cycles, which range from milliseconds to seconds, but with a very precise interval. This regularity turns the ataracs into a special observational tool.

There are three distinct classes of pulsars, classified according to the source of their electromagnetic radiation: rotating pulsars, accreting pulsars, and magnetars. All of these are neutron stars, but their observable behavior and underlying physics are quite different.
