QQ Vul: The longest period AM Her system

摘要

The activities at Penn State University on QQ Vul: The Longest Period AM Her System are described. This final report covers the entire grant period, from initiation, 15 July 1991, to the planned conclusion, 15 July 1992, through the no-cost extension date, 15 July 1993. The purpose of this grant was to support the data analysis of my approved ROSAT Guest Investigator program to observe QQ Vul, a cataclysmic variable of the AM Herculis type. The observations of QQ Vul were conducted in October, 1990, but despite this early collection of data, trouble with the SASS software which performs the pipeline data reduction prevented my receiving any useful data until more than one year later.
