Cataclysmic variable star in Draco = PNV J18422792+4837425.

MUNARI U.

Abstract (from CDS):

U. Munari, Istituto Nazionale di Astrofisica, Padova Astronomical Observatory, reports that he acquired a spectrogram of PNV J18422792+4837425, which is visible where the Palomar Sky Survey images show an empty field. Munari's spectrogram (resolution 0.23 nm/pixel; range 320-780 nm) was taken on Sept. 6.841 UT with the 1.22-m telescope of the Asiago Astrophysical Observatory. The spectrum is dominated by an absorption continuum similar to that of an A-type star – with H_alpha in emission, filling in the corresponding absorption, and H_beta appearing as an emission core within the absorption profile. The H_alpha and H_beta emission lines are very sharp (gaussian-like), not wider than the instrumental profile. Overall, the spectrum is very typical of a cataclismic variable close to maximum brightness.
