Soft X-ray transient

ID: soft-x-ray-transient

A Soft X-ray Transient (SXT) is a type of astronomical object that typically refers to a transient source of soft X-rays, often associated with binary star systems where one of the components is a compact object such as a black hole or neutron star. These systems are usually characterized by rapid increases in X-ray brightness followed by periods of relative quiescence.
