Scientific paper

Nova Velorum 1999 (V382 Vel) was detected 12 days after the outburst discovery with the BeppoSAX MECS and LECS with a count rate 0.1537+/-0.0020 cts -1 and 0.0620+/-0.0026 cts s-1 respectively. It was not detected at higher energies. The LECS-MECS combined spectrum shows huge intrinsic absorption of the nebular ejecta, so the site of X-ray emission must have been deeply inside the nebular material at the time of observation. The spectrum can be fitted with a multiple component model of thermal plasma with at least one component at temperature kT>=10 keV, and the flux is 1.5-2×10-11 erg cm-2 s-1. There is no supersoft emission of the central source due to the heavy absorption of the shell. .
