SUMMARY OF SEQUENCE NUMBER 300018
Title: HETG SPECTROSCOPY OF BRIGHT INTERMEDAITE POLARS
Observer: MUKAI
Subject Category: WD Binaries and CVs
Seq: 300018 ObsId: 00649
Long-term Plan bin: 24-Apr-2000
ABSTRACT
Intermediate Polars (IPs) are the hard X-ray brightest subclass of magnetic Cataclysmic Variables. Previous X-ray observations, notably those with ASCA, have established the complex nature of their spectra: multi-temperature plasma and complex absorber are both required. Moreover, one recent study suggests that the Fe lines are Compton broadened in at least some systems. We propose HETG observations of 2 bright IPs, V1223 Sgr and AO Psc, to search for K-alpha lines of Ne, Mg, Si, S, Ar and Ca; to measure the physical widths of any lines we do detect; to search for a direct evidence for an ionized absorber; and to obtain an improved characterization of the spin modulation.
