  Title: AN X-RAY STUDY OF THE ASYNCHRONOUS POLAR RX J1940.2-1025                        


Abstract:
 RX J1940.2-1025, recently discovered to be the source responsible for the periodic
 signals previously associated with NGC 6814, is now known to be an AM Her system.
 Optical observations and a re-evaluation of earlier X-ray data have shown that this
 object has a number of unusual features. We propose detailed observations of RX
 J1940.2-1025 with ASCA in order to: (i) understand the origin of the prominent dip,
 i.e., absoprtion due to the accretion column or the eclipse by the secondary; (ii)
 understand the accretion geometry of RX J1940.2-1025 through phase-resolved
 spectroscopy; (iii) perform the first detailed study of the hard X-ray component.
