Nested dust shells around the Wolf-Rayet binary WR 140 observed with JWST
Hamaguchi, Kenji; Corcoran, Michael F.; Morris, Mark R. +29 more
Massive colliding-wind binaries that host a Wolf-Rayet (WR) star present a potentially important source of dust and chemical enrichment in the interstellar medium. However, the chemical composition and survival of dust formed from such systems is not well understood. The carbon-rich Wolf-Rayet binary WR 140 presents an ideal astrophysical laborato…
The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Ventura, Paolo; Amram, Philippe; Mendes de Oliveira, Claudia +66 more
Planetary nebulae—the ejected envelopes of red giant stars—provide us with a history of the last, mass-losing phases of 90% of stars initially more massive than the Sun. Here we analyse images of the planetary nebula NGC 3132 from the James Webb Space Telescope (JWST) Early Release Observations. A structured, extended hydrogen halo surrounding an …
