Title: Spectral classification of novae in M31
Abstract:
We aim to work on the global distribution modeling of novae in M31
and to investigate the open question of a possible bimodal (disk/bulge)
population split. To support this project, we require optical
observations (spectra as well as photometry) to classify the novae
included in our study. Follow-up with X-ray observations using Swift,
XMM-Newton, and Chandra will be used to correlate their spectral type,
and decline rate of the light curve with its corresponding X-ray phase.
The spectral classification of novae is essential to our project in
interpreting the correlation between nova type, location within M31
(bulge/disk), temporal decay behavior in the optical regime, and
temporal/spectral behavior in the X-ray regime (Super-Soft Source phase,
or otherwise). We detect approximately 2 novae per month in M31.
Typical peak brightnesses are 15 mag, but drop to 20 mag within a few
weeks. Because of this rapid decline, we request Target of Opportunity
follow-up spectroscopy for bright post-discovery novae visible from
KPNO.
