X-ray emission from A-type stars

open access: yesAstronomy and Astrophysics, 2007
Being fully radiative, stars of spectral type A are not expected to harbor magnetic dynamos and hence such stars are not expected to produce X-ray emission.

X-ray emission from Be star/X-ray binaries

Space Science Reviews, 1994
Observations of X-ray emission from Be star/X-ray binaries are reviewed. Some optical characteristics of these binaries are also presented. Theoretical aspects pertaining to the X-ray emissions are given.

The Sun as an X-Ray Star: Overview of the Method

Solar Physics, 1997
We present a method to study the solar-stellar connection, i.e., the close similarity of the physical phenomena occurring on the Sun and on late-type active stars, by taking advantage of Yohkoh/SXT X-ray images. From such images, we first find the distributions of the whole disk differential emission measure, and from them we then synthesize spectra ...

Cooling of neutron stars and X-ray observations

Space Science Reviews, 1981
Cooling of neutron stars is calculated using an exact stellar evolution code. The full general relativistic version of the stellar structure equations are solved, with the best physical input currently available. For neutron stars with a stiff equation of state, we find that the deviation from the isothermality in the interior is significant and that ...
