Diagnosing grain growth in a dense cloud with JWST

Nature Astronomy volume 8, pages 271–272 (2024)Cite this article

Subjects

The size distribution of solid grains in dense clouds is a key parameter to constrain in order to understand grain growth, which influences the nature and timescale of the formation of protoplanets. A JWST study has quantified the grain size distribution by modelling the spectral absorptions arising from ice components of grains before protostellar collapse.
