Observations of cataclysmic variables for Astro-2, EUVE, Voyager, and ASCA satellites AND Reminder regarding outburst of 0749+22 U Gem
Active Dates: Feb. 13, 1995 – March 17, 1995
Abstract:
The NASA satellite Astro-2 is scheduled to be launched from the space shuttle on March 1, 1995. Astro-2 is a follow up to Astro-1, launched in December of 1990. This mission will involve observing cataclysmic variables both in outburst and in quiescence using the Hopkins Ultraviolet Telescope. Additionally, the satellites Extreme Ultraviolet Explorer (EUVE), Voyager, and the Japanese ASCA will observe these stars simultaneously.
Justification:
The instruments aboard the satellites are ideal for studying the structure and evolution of the disk and winds in dwarf novae through outburst, the boundary layer in cataclysmic variables, and the temperature, size, and accretion column of the white dwarf component of magnetic cataclysmic variables like AM Her.
