Discovery of SiC and Iron Dust Around AGB Stars in the very Metal-Poor Sextans A Dwarf Galaxy with JWST: Implications for Dust Production at High Redshift
M. L. Boyer, G. C. Sloan, A. Nanni +23
Low-resolution infrared spectroscopy from JWST confirms the presence of SiC and likely metallic iron dust around asymptotic giant branch (AGB) stars in the Sextans A dwarf galaxy,…

Equatorial Enhancement in the Dustiest OH/IR Stars in the Galactic Bulge
Steven R. Goldman, Jacco Th. van Loon, Olivia C. Jones +2
We have detected the 10 um silicate feature and the 11.3 um crystalline forsterite feature in absorption in 21 oxygen-rich AGB stars in the Galactic Bulge. The depths of the 10 um…
