JOYS: A JWST/MIRI survey of the evolution of H winds and jets from low-mass protostars
L. Francis, Å. Tychoniec, E. F. van Dishoeck +20
Protostellar outflows display wide-angle winds and collimated jets, the magnetocentrifugal launching of which enables accretion onto the protostar. The majority of the outflow mass…

A JWST/MIRI view of k Andromedae b: Refining its mass, age, and physical parameters
N. Godoy, E. Choquet, E. Serabyn +7
Context. kAndb is a substellar companion near the planet-brown dwarf boundary, orbiting a B9IV star at 50-100 au. Estimates of its age and mass vary, fueling a decade-long debate.…

JWST observations of segregated CO and CO ices in protostellar envelopes
N. G. C. Brunken, A. C. A. Boogert, E. F. van Dishoeck +13
The evolution of interstellar ices can be studied with thermal tracers such as the vibrational modes of CO ice that show great diversity depending on their local chemical and t…
