Description

The results are given of an isodensitometric and spectrophotometric investigation of the cometary nebula P 21 and its associated nucleus. The shape of the isodensities of the nucleus differs from those for normal stars, and in this the nucleus recalls R Mon. A spectral investigation of the nucleus of P 21 made on the basis of observations during 1981-1982 shows that it is a star of the class F2-F5V with an envelope expanding at about 120 km/sec
