Abstract
IN view of the dramatic recent history of Eta Carinae1 and the violent motions within the nebulous envelope immediately surrounding it2, we have studied this object for short-period optical oscillations in the 1968–69 observing season. Following the suggestion by Ostriker and Gunn3 that the various optical phenomena may be excited by a pulsar, we extended the original search to still higher frequencies.
