... 2002 September 14 . X-Ray Moon . ... Consider the image in three parts: the bright hemisphere of the x-ray moon, the darker half of the moon, and the x-ray sky background. The bright lunar hemisphere shines in x-rays because it scatters x-rays emitted by the sun . ... Still, the few x-ray photons which seem to come from the moon's dark half are currently thought to be caused by energetic particles in the solar wind bombarding the lunar surface. ...

... There are several explanations for these X--ray quiet PMS stars. To examine the explanations, it is proper to divide the PMS stars into three groups: those bluer than R - I = 0.7, those redder than the X--ray sources (R - I > 1.25) and those with colors similar to the X--ray sources. ... A total of 26 of the non--X--ray detected PMS candidates had spectra taken. ... Between V=14 and V=16, I find 25 stars which are X--ray sources and estimate 19 non--X--ray PMS stars. ...
