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…
The converging gas flow around the infrared dark cloud G28.3
H. Beuther, C. Gieser, H. Linz +7
Aims: The G28.37+0.07 star-forming region is a prototypical infrared dark cloud (IRDC) located at the interface of a converging gas flow. This study characterizes the properties of…
CASCADE: Filamentary accretion flows in Cygnus X DR20
M. Sawczuck, H. Beuther, S. Suri +11
Aims. We investigate the role of filaments in high-mass star formation, whether gas flows from large to small scales along them, and what their properties might reveal about the re…
ALMAGAL V. Relations between the core populations and the parent clump physical properties
D. Elia, A. Coletta, S. Molinari +54
Context. The fragmentation of massive molecular clumps into smaller, potentially star-forming cores plays a key role in the processes of high-mass star formation. The ALMAGAL proje…
Filamentary accretion flows in high-mass star-forming clouds
J. -E. Schneider, H. Beuther, C. Gieser +11
We quantify the gas flows from a scale of up to several parsecs down to the sub-parsec scale along filamentary structures in the three high-mass star-forming regions G75.78, IRAS21…
From theory to observation: understanding filamentary flows in high-mass star-forming clusters
M. R. A. Wells, R. Pillsworth, H. Beuther +2
Here we use data from multi-scale galactic MHD simulations to observe filaments and star forming clumps on 10's of pc scales and investigate flow rate relationships along, and onto…
