Sumario: | On the basis of material taken at Bosque Alegre, (dispresion 42 A/nm), this star shows the following peculiarities:
a) the approximate spectral type is O7; b) the Balmer series is visible up to n=9; c) the He I series is very weak for the spectral type; d) the Pickering series is very much enhanced; e) there are abnormalities in other elements: nitrogen is slightly enhanced, oxygen practically absent and carbon is very weak. According to the Stark effect in the Balmer series, the star appears to be sub-luminous. The paper will be published in full elsewhere. |
