Outburst of HS 2331+3905
Abstract:
The WZ Sge-candidate HS 2331+3905 is currently undergoing its first observed outburst. The outburst's significant rise in magnitude and spectral transitions suggest it is a WZ Sge-type dwarf nova with a particularly interesting white dwarf primary that could provide new insights into white dwarf asteroseismology.
Justification:
The rise of more than seven magnitudes from the quiescent level of m(V) ~ 16.4 strongly suggests that this is indeed a WZ Sge-type dwarf nova. If the outburst results in temperature or other changes in the white dwarf, these may change its pulsation behavior and provide new clues for white dwarf asteroseismology.
