An Infrared Cavity May Be T Pyxidis's Super-Remnant
The reported shell-like structure could record repeated eruptions from the recurrent nova.
Summary
The reported shell-like structure could record repeated eruptions from the recurrent nova.
A short research note reports an apparent infrared cavity around the Galactic recurrent nova T Pyxidis and proposes that it may be a nova super-remnant built by repeated ejecta. Such remnants are predicted to span tens of parsecs around recurrent novae. The identification is explicitly tentative and requires follow-up; the paper reports evidence for a candidate, not a confirmed remnant.
Why it matters
The reported shell-like structure could record repeated eruptions from the recurrent nova.
