S. Eyres, J. M. Oliveira, NM Ashok, J Krautter, TJ O'Brien, K. L. Page, M. T. RushtonWe present Spitzer Space Telescope and Herschel Space Observatory infrared observations of the recurrent nova T Pyx during its 2011 eruption, complemented by ground-base optical-infrared photometry. We find that the eruption has heated dust in the pre-existing nebulosity associated with T Pyx. This is most likely interstellar dust swept up by T Pyx — either during previous eruptions or by a wind — rather than the accumulation of dust produced during eruptions.
