You wait ages and two recurrent nova remnant papers come up in the same week!
This MNRAS submission is on the RN T Pyx. The title is “3D physical structure and angular expansion of the remnant of the recurrent nova T Pyx”: https://arxiv.org/abs/2402.07879
The last eruption of T Pyx was in 2011. The remnant has a bipolar structure. The expansion velocity is ~460 km/s.
