Scientific paper

Spectroscopic data in the blue, red and infrared regions of HD 141569 are presented. The star has a spectral type A 0 and presents the exceptional behavior of having the Paschen series in absorption and O I 7772 A in strong emission. A discussion of other relevant data and the fact that no photometric variability was detected makes it difficult to assign the star to any one of the groups of emission line stars. Probably, it corresponds to the quiescent phase of an 'Herbig Ae-Be' object.
