White dwarf star system is producing mysterious radio signals
Radio astronomers have discovered an unusual phenomenon in recent years. They detected radio pulses from the Milky Way that last from seconds to minutes. These pulses differ from those produced by known radio-emitting neutron stars or pulsars, which typically last only milliseconds.
An international team of astrophysicists led by the Netherlands and the UK have discovered that radio pulses lasting seconds ...

In 2015, astrophysicists discovered a system consisting of two compact stars orbiting each other: a pulsar (i.e., a highly ...
The pulsar and the objects that orbit it are already ... but differ under extreme circumstances. That puts star systems intense enough to serve as test laboratories for General Relativity and ...

have the primary goal of detecting gravitational waves from supermassive black hole binary systems at the centers of merging galaxies by observing an entire array of pulsars distributed throughout ...
are known as millisecond pulsars (MSPs). Astronomers assume that they are formed in binary systems when the initially more massive component turns into a neutron star that is then spun up due to ...
"We apply the model to candidate systems, spider pulsars, which are binary stars composed of one millisecond pulsar and a very low-mass companion star that is heavily irradiated by the ...
