Butters, O.W., Barlow, E.J., Norton, A.J., Mukai, K. 2007, A&A, 475, L29-L32.
Type
Observational: X-ray Photometry and Spectrscopy.
Object(s)
V667 Pup.
Results
The spin period of 512.4 s is clearly established using a 36 ksec RXTE observation of V667 Pup, and it has an X-ray spectrum typical of IPs, thus confirming its IP status. X-ray orbital modulation is not seen if the 5.6 hr period seen in optical spectroscopy is correct, although there appears to be a modulation at the 11.2 hr period suggested earlier.
