TL;DR
This study uses infrared observations from space telescopes to show that the 2011 eruption of T Pyxidis heated pre-existing interstellar dust, revealing insights into dust interaction with recurrent nova eruptions.
Contribution
First infrared analysis of T Pyxidis's 2011 eruption demonstrating dust heating and identifying the dust as interstellar rather than nova-produced.
Findings
Eruption heated pre-existing dust in the nebula
Dust is likely interstellar swept-up material
Infrared observations reveal dust glow post-eruption
Abstract
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.
