Stellar X‐ray accretion signatures

Astronomische Nachrichten, 2017
Accretion is observed in a wide range of objects with partially overlapping properties. In this paper, we focus on accretion in young stars. Material impacting the stellar surface is shock‐heated to temperatures of a few 106 K (MK), which is ideally suited for observations in the X‐ray regime.

Stellar Accretion and X-ray Emission

Nature, 1967
Shklovsky has suggested that the Scorpius X-ray source is a binary pair and that the X-radiation arises from the collision of material from a giant star with a neutron star. The theoretical complications of such a model are now found not to match actual measurements and it is suggested that the bremsstrahlung effect occurs between a giant star and a ...

Stellar accretion in active galactic nuclei

Monthly Notices of the Royal Astronomical Society, 1993
The Seyfert galaxy NGC 6814 is unique in showing evidence of a periodicity in its X-ray light curve, first seen in EXOSAT data and then confirmed by a Ginga observation. A further Ginga light curve of this source taken 18 months later shows that the periodic signal is still present.
