"X-ray emission from classical novae"

Detection of X-ray emission from classical novae in their
 post-outburst stages provides crucial information about 
the nova phenomenon. The soft X-ray emission gives a direct
 insight into the remaining hot nuclear burning shell, 
while the hard X-ray emission provides a diagnostic of the
conditions in the nova shell and the possible resumption of
 accretion.

In this talk, I will overview my current PhD work, both 
theoretical and observational. In the first part, white dwarf
 envelope models with stationary hydrogen burning will be 
presented. Properties of the X-ray emission of the post-nova
 white dwarf are obtained, and the results will be compared to
 ROSAT observations. The second part of the talk will deal
with XMM-Newton observations of Nova Sgr 1998 and Nova Oph 1998.
