de Martino et al. 2006b

Bibinfo (this paper at ADS): de Martino, D., Matt, G., Mukai, K., Bonnet-Bidaud, J.-M., Burwitz, V., Gaensicke, B.T., Haberl, Mouchet, M. 2006, A&A 454, 287-294.
Type: Observational: X-ray spectroscopy and photometry.
Object(s): UU Col.
Results: X-ray power spectrum is dominated by the 863 s spin signal, but the 3.5 h orbital and the 935 s beat signals are also seen (disk overflow accretion). UV and optical modulations are anti-phased. X-ray spectrum can be fitted with 0.2 keV and 11 keV optically thin emission and a 50 eV blackbody, whose ratio is consistent with expectations. Magnetic field is too weak for UU Col to evolve int a polar.
