Descripción
We present near IR photometry and spectrophotometry of two unusual novae
observed in 1991: Nova Herculis and Nova Scuti. Both are seen to have
unusual spectral and light curve characteristics, the former due to the
very formation of a dust cloud surrounding the nova and the second
because of what is interpreted to be high interstellar reddening. Both
novae present strong and well defined Brackett gamma lines, although in
the former this line disappeared rapidly due to blanketing from the
circumstellar dust cloud. Considerable differences are seen between the
visible and IR light curves of both objects. Nova Herculis is found to
be the fastest nova ever observed in the visible with a time to decay 3
mag from maximum (t 3) of 2.8 d.
