Nova Herculis, 1934

Abstract

THE light curve of this nova continues to be abnormal: after oscillating between 2^m and 5^m during the months January to March, the star has faded rapidly during the first half of April to 10^m on April 14. At the same time, the spectrum has altered, the chief new lines being due to [Fe II], represented by emission maxima displaced to the violet. The two maxima previously present in H, [O _I] and Fe II can now be seen only in the hydrogen bands. These have faded along with the continuous spectrum, and on April 15 much the strongest line in the spectrum was [O _I] 6300 ; the spectrum now consists predominantly of the forbidden lines of [Fe _II], [N _II] and [O _I], resembling in many respects that of n) Carinse.
