E., Smith, C., Sullivan, H., Watson, S.

Classical novae are shock-powered multi-wavelength transients triggered by a thermonuclear runaway on an accreting white dwarf. V1674 Her is the fastest nova ever recorded (time to declined by two magnitudes is t_2=1.1 d) that challenges our understa

Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sources and periods of variability precisely and to classify this X-ray sou

Accretion-disc precession in UX Ursae Majoris

Autor: de Miguel, E., Patterson, J., Cejudo, D., Ulowetz, J., Jones, J. L., Boardman, J., Barret, D., Koff, R., Stein, W., Campbell, T., Vanmunster, T., Menzies, K., Slauson, D., Goff, W., Roberts, G., Morelle, E., Dvorak, S., Hambsch, F. -J., Starkey, D., Collins, D., Costello, M., Cook, M. J., Oksanen, A., Lemay, D., Cook, L. M., Ogmen, Y., Richmond, M., Kemp, J.

We report the results of a long campaign of time-series photometry on the nova-like variable UX Ursae Majoris during 2015. It spanned 150 nights, with ~1800 hours of coverage on 121 separate nights. The star was in its normal `high state' near magnit
