Spectral Atlas of Southern Novae

Layout of the Atlas

The layout of this atlas is designed to collect the data by the individual novae, rather than to facilitate intercomparison of novae.

This atlas is still evolving. It is not completely homogenous. There are some errors of both commission and omission, which we are rectifying.

The opening page lists the novae that we have observed. Click on the name of the nova to go the data collection for that nova. The parenthetical remarks that follow the nova indicate:

pPhotometric data exist
*Nova is no longer being actively observed

Main Nova Page

The main page for each nova includes one or two finding charts. The image on the left, which can be enlarged by right-clicking "view image", shows a 5 x 5 arcmin region in V, and generally shows the nova when bright. The smaller image on the right shows a 1.2 x 1.2 arcmin region of one of the last images we obtained that show the fading nova. The date and filter are chosen to show the now-faint object. Observation dates are shown on the images in YYMMDD format.

The coordinates are generally taken from the IAU Circulars or some other published report. The discovery date is the earliest date we have found when the nova was seen to be bright. This is not necessarily the time of maximum. We do not supply here the time of the latest pre-discovery null detection. It is of course important to have this in order to estimate the time of maximum.

Nova Data Pages

Three self-explanatory links follow.

At the present time, only the photometry are available digitally. The spectra can be viewed as gif images. At a later date, time- and funding-permitting, we will make the spectral data available as fits files.

In some cases the amount of spectral data have warranted making a movie to show the spectral evolution. These movies are made by linearly-interpolating the available spectra to 1 or 2 day centers. All spectra are normalized to the continuum level. The evolution of the lines is clearly evident. Rapid changes in the continuum slope are due to flux calibration errors.

Left-click on the link to start the movie. The upper panel shows the light curve; the vertical line shows the time of the interpolated spectrum.
