Abstract (from CDS):

We 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.

Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA. Erratum: Herschel/SPIRE observations of the TWA brown dwarf disc 2MASSW J1207334-393254*
