Dwarf Novae, Ll Andromedae

Scientific paper

We present the first detailed observations of LL Andromedae made during a recent rare outburst. Photometric and spectroscopic observations were obtained as well as a precise position. We have confirmed that this star is indeed a dwarf nova. Superhumps were observed at maximum light and the outburst amplitude is near 6 magnitudes. These two facts lead to the conclusion that LL And is likely to have a short orbital period (1.32 hr) and may belong to the Tremendous Outburst Amplitude Dwarf Novae (TOAD) subclass.
