The on-off cycles have characteristic times of the order of days or weeks, and
absorption features may last hours. 3) At still greater distances from the X-ray
source, the flow of gas from the companion star, as well as the density
dependence on ...

These are the absorption dips and absorption trough . The existence of
absorption dips in the light curve of Cyg X - 1 has received considerable attention
since their discovery by MASON , HAWKINS , SANFORD , MURDIN and
SAVAGE [ 38 ] ...

One also would like to know the total visual absorption in order to be able to
estimate the distance to the source using the observed visual flux and luminosity
class . Reasonable distance estimates to individual sources can be obtained by ...
