Dwarf Novae
There are different kinds of novae. The Dwarf Novae
(also called SS Cygni or U Geminorum stars) are
repeating variable novae with a range up to six
magnitudes. These dwarf novae repeat their outbursts
at quasi-periodic intervals of a few weeks or months
and are faint at minimum and around zero magnitude
at maximum.
Recurrent Novae
The Recurrent Novae, much larger than the dwarf
novae (they range in light between 8 and 10
magnitudes, undergo outbursts at irregular intervals of
several decades. The fact that a star can undergo the
nova process more than once is thought provoking.
As violent as the nova process may appear, it seems
to be but a passing incident in the life of the star,
which returns to very much the same condition that
existed before the outburst. As we shall see later in
the text, this is not true for the supernovae. The
variable star T Coronae Borealis is a classic recurrent
nova with outbursts in 1866 and in 1946.
Novae
The normal novae are brighter still than either the
dwarf or the recurrent novae, and more common.
More than 100 novae have been observed in our
galaxy in the last one hundred years. It is estimated
that about 25 novae brighter than 9th magnitude
occur in our galaxy each year; although all are not
visible due to either their intrinsic faintness or daytime
skies.
Novae are designated by constellation and year of
appearance. Novae Aquilae 1918 was the brightest
seen this century. Most novae have an average range
175
