HST Results on Cataclysmic Variables

By Mary Ingersoll
October Meeting

Dr. Paula Szkody Professor
Wednesday, October 18
7:30 p.m.

A-102 Physics-Astronomy Bldg.
University of Washington

Come early at 7 p.m. to visit with your fellow members.

Bring your slides for after the program.

DR. Paula Szkody will be our guest speaker at the October 18 SAS meeting. She will discuss recent Hubble Space Telescope (HST) results on cataclysmic variables. Dr. Szkody uses a multi-wavelength approach to observational studies of close binary stars (stars whose orbits are roughly one solar radius or less).

She is an active user of the Hubble Space Telescope, the Extreme Ultraviolet Explorer, the ASCA, ROSAT, and XTE X-ray satellites as well as ground-based optical facilities around the world. These studies have led to insights into the nature of mass transfer and accretion onto magnetic and non-magnetic white dwarfs, the structure of accretion disks and their X-ray-emitting boundary layers, stellar coronae, and the effects of irradiation on the upper atmospheres of late-type secondary stars. These results help to elucidate the long-term evolution leading to the formation of these ultra-short period binaries.

Dr. Szkody has been with UW Astronomy dept. since 1975. See Paula's Astronomy Page at: http://www.astro.washington.edu/szkody/.
