PAN-CHROMATIC OBSERVATIONS OF THE REMARKABLE NOVA LARGE MAGELLANIC CLOUD 2012

We present the results of an intensive multiwavelength campaign on nova LMC 2012. This nova evolved very rapidly in all observed wavelengths. The time to fall two magnitudes in the V band was only 2 days. In X-rays the super soft phase began 13 + or - 5 days after discovery and ended around day 50 after discovery. During the super soft phase, the Swift/XRT and Chandra spectra were consistent with the underlying white dwarf (WD) being very hot, ~1 MK, and luminous, ~10 super(38) erg s super(-1). The UV, optical, and near-IR photometry showed a periodic variation after the initial and rapid fading had ended. Timing analysis revealed a consistent 19.24 + or - 0.03 hr period in all UV, optical, and near-IR bands with amplitudes of ~0.3 mag which we associate with the orbital period of the central binary.
