The structure of a recent nova shell as observed by ALMA
Diaz, Marcos; Abraham, Zulema; Ribeiro, Valério A. R. M.; Beaklini, Pedro P. B.; Takeda, LarissaHigh resolution ALMA observations of the recent (2.52 yr old) shell of Nova V5668 Sgr (2015) show a highly structured ionized gas distribution with small (10^15 cm) clumps. These are the smallest structures ever observed in the remnant of a stellar thermonuclear explosion. No extended contiguous emission could be found above the 2.5σ level in our data, while the peak hydrogen densities in the clumps reach 10^6 ...
