Paula Szkody, professor of Astronomy at the University of Washington, will speak at the July 21 meeting of the Seattle Astronomical Society (SAS).

Paula works on cataclysmic variables, mainly ultra short dwarf novae. Approximately 50 percent of the stars in the universe are members of double star systems. When one of the stars in such a system is a white dwarf, conditions are right for a novae. Novae can recur with the same star. There are two types of novae: classical and dwarf. Paula Szkody works mainly with dwarf novae. Outbursts from dwarf novae occur many times and do not eject a shell of gas.

These are not to be confused with supernovae, which are one-time explosions at the end of a star's life. While type I supernovae involve white dwarfs, type II do not.

Amateurs participate in the hunt for novae through the American Association of Variable Star Observers. This is an organization that several of us might find quite interesting and participate in.

We meet July 21 at 7:30 p.m. in room 102A of the Physics/Astronomy building on the University of Washington campus in Seattle.
