Evidence of Enhanced Ionization in Protostellar Envelopes
Kamber R. Schwarz, S. Maret, M. R. A. Wells +4
Ionization is a major driver of both physical and chemical evolution in protostellar systems. Recent observations reveal substantial chemical processing in protoplanetary disks by…
Unlocking accretion rate diagnostics for high-mass protostars using JWST/MIRI HI lines
S. D. Reyes-Reyes, H. Beuther, E. F. van Dishoeck +14
While many aspects of high-mass star formation have been investigated, the accretion onto the central protostars is one of the most fundamental but less explored physical propertie…

María Teresa Valdivia-Mena, Jaime E. Pineda, Caroline Gieser +24
(Abridged) Recently, streamers have been observed causing shocks at the outer edge of protoplanetary disks. The study of sulfur-bearing species can help us to understand the physic…
JOYS: JWST MIRI/MRS spectra of the inner 500 au region of the L1527 IRS bipolar outflow

C. Gieser, P. Caselli, D. M. Segura-Cox +19
Star formation is a hierarchical process ranging from molecular clouds down to individual protostars. In particular how infalling asymmetric structures, called streamers, deliverin…
