Abstract:
The effects of rotation are investigated on the source functions in an expanding atmosphere. We have considered a non-LTE two-level atom in an extended atmosphere. We have also made use of von Zeipel`s theorem in giving the incident radiation at Tou = Toumax. Uniform rotation is assumed and the values of the ratios of the centrifugal force and gravity force at the equator are taken to be 0.1, 0.4, 0.8 corresponding to a uniform rotational velocity of 1, 4 and 8 mtu. It is found that rotation will dilute the rotation field which is similar to the effects of expansion.
