The presence of strong helium-like forbidden lines places the source of X-ray emission at tens to hundreds of stellar radii from the photosphere. Variability was present in X-rays and simultaneous optical photometry, but neither were correlated with the known period of the system or with each other. An enhanced abundance of sodium revealed nuclear processed material, a quantity related to the e","authors_text":"Andrew M. T. Pollock, David P. Huenemoerder, Joy S. Nichols, Kenneth G.
