****************************************************** PR # 42007 We have been awarded 40 ksec of XTE time to observe the hard X-ray spectrum of the prototypical RS CVn binary HR 1099. This will enable us to detect its X-ray spectrum up to 35 keV even in its quiescent state, and to even harder energies if it flares. We propose to obtain an ASCA observation simultaneously with this XTE observation, so that we can obtain a moderate spectral resolution spectrum of the .5-8 keV range to complement the low-resolution (but broad-band) XTE spectrum. This joint observation should enable us to accurately characterize the coronal components present in HR 1099, and to search for a proposed hard X-ray emission component. There is a good chance that the X-ray emission will be variable, and if so we will study the spectral variability as a function of time ******************************************************
