(something in the sky generating X-ray signal)
An X-ray source is an object, or a location in
the celestial sphere from which X-rays are detected.
The term X-ray source avoids interpretation (i.e.,
any declaration what kind of object is producing the X-rays),
though it is often used even when a certain type of source
is assumed. X-ray astronomy began in full with the development
of X-ray space observatories.
Shock and magnetic fields can be factors in producing
the heat to produce discernible X-ray black-body radiation.
Stars (e.g., the Sun) produce X-rays, such as that from the
corona which includes plasma significantly hotter than the
stellar surface. X-ray is found from some pre-main-sequence stars, some
early stars, and some cool stars such as M dwarves
and brown dwarfs.
