V697 Sco: an IP?

   Back to an old issue.  V697 Sco (Nova Sco 1941) has been proposed to be
an intermediate polar.  This nova did not show apparent oscillations.
Does this observation imply that IPs and nova oscillations are not
related (?) > Any comments, Alon?

Title: Nova Scorpii 1941 (V697 Sco): A Probable Intermediate Polar
Authors: Brian Warner (Univ. of Cape Town) and Patrick A. Woudt (Univ. of Cape
  Town)
Comments: To appear in the November 2002 issue of PASP
\\
  V697 Sco, the remnant of Nova Scorpii 1941 and currently at V ~ 20.0, is
found from photometric observations to have the characteristics of an
intermediate polar (IP) with an orbital period (Porb) of 4.49 h and a rotation
period (Prot) of 3.31 h. It therefore appears to be a member of the rare class
of IPs where Prot ~ Porb, which are probably discless systems. The prominence
of the modulation at 0.5 Prot, and its orbital sidebands, indicates two-pole
accretion.
