Abstract
The star forming region in Cep A is at present unique. It consists of two strings of the most compact HII regions yet detected, each region appearing to be produced by a B3 star, and all are contained inside a diameter of 40″, or 0.1 pc for the distance of 725 pc. OH and H20 masers are associated with the central regions, and these normally indicate star formation, but the linear dimensions of the regions of 200 to 800 au suggested initially that they were no more than 1,000 years old. Measurment of the spectral indices of the regions are consistent with mass-loss due to stellar winds, which may account for their small size, and give some indication of how B3 protostars evolve.
