The CepA disk-outflow system at <=0.2'' or <=100au resolution
H. Beuther, C. Gieser, V. Aberham +21
Context: Although there has been significant progress, the physical properties and potential fragmentation of accretion disks around high-mass protostars remain poorly constrained.…
Protostellar Outflows at the EarliesT Stages (POETS). IX. Magnetohydrodynamic disk winds traced by SO and SO in luminous protostars
L. Moscadelli, H. Beuther, A. Sanna +13
We investigate two massive young stellar objects (YSOs), IRAS21078+5211 and G035.02+0.35, where evidence for magnetohydrodynamic (MHD) disk winds (DWs) has been obtained at scales…
PRODIGE - envelope to disk with NOEMA: VII. (Complex) organic molecules in the NGC1333 IRAS4B1 outflow: A new laboratory for shock chemistry
Laura A. Busch, J. E. Pineda, P. Caselli +20
Shock chemistry is an excellent tool to shed light on the formation and destruction mechanisms of complex organic molecules (COMs). The L1157-mm outflow is the only low-mass protos…
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…
Observations of sulfuretted species in HL Tau
P. Rivière-Marichalar, R. le Gal, A. Fuente +4
Protoplanetary disks inherit their chemical composition from their natal molecular cloud, but the extent to which this material is preserved versus reset through chemical reprocess…
