| Abstract | We propose a 60ks observation of a new bright (V<7.5) nova likely tobe detected in gamma-rays. The observation will probe shocks withinthe nova ejecta, constrain the non-thermal particle acceleration and gamma-rayproduction mechanisms. We will put an upper limit on the particle accelerationefficiency by comparing thermal X-ray and optical to GeV luminosity and searchfor predicted non-thermal X-rays. Understanding shocks in novae is r^ant forother shock-powered transients including Type IIn supernovae, tidal disruptionevents and stellar mergers. NuSTAR is the only instrument capable of detectinghard X-rays from novae simultaneously with the GeV emission. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
