The Structure and Kinematics of Three Class 0 Protostellar Jets from JWST
Samuel A. Federman, S. Thomas Megeath, Alessio Caratti o Garatti +20
We present observations of jets within 2000 au of three deeply embedded protostars using 2.9-27 micron observations with JWST. These observations show the morphologies and kinemati…
HDO ice detected toward an isolated low-mass protostar with JWST
Katerina Slavicinska, Łukasz Tychoniec, María Gabriela Navarro +15
Water is detected in environments representing every stage of star and solar system formation, but its chemical evolution throughout these stages remains poorly constrained. Deuter…
The relation between the Mass Accretion Rate and the Disk Mass in Class I Protostars
Eleonora Fiorellino, Lukasz Tychoniec, Carlo F. Manara +5
The evidence of a relation between the mass accretion rate and the disk mass is established for young, Class II pre-main sequence stars. This observational result opened an avenue…
Complex organic molecules in low-mass protostars on solar system scales -- I. Oxygen-bearing species
M. L. van Gelder, B. Tabone, Ł. Tychoniec +8
Complex organic molecules (COMs) are thought to form on icy dust grains in the earliest phase of star formation. The evolution of these COMs from the youngest Class 0/I protostella…
Chemical and kinematic structure of extremely high-velocity molecular jets in the Serpens Main star-forming region
Łukasz Tychoniec, Charles L. H. Hull, Lars E. Kristensen +3
The fastest molecular component to the protostellar outflows -- extremely high-velocity (EHV) molecular jets -- are still puzzling since they are seen only rarely. The first aim is…
The VLA Nascent Disk And Multiplicity Survey of Perseus Protostars (VANDAM). IV. Free-Free Emission from Protostars: Links to Infrared Properties, Outflow Tracers, and Protostellar Disk Masses
Łukasz Tychoniec, John J. Tobin, Agata Karska +11
Emission from protostars at centimeter radio wavelengths has been shown to trace the free-free emission arising from ionizing shocks as a result of jets and outflows driven by prot…
The Herschel-PACS legacy of low-mass protostars: Properties of warm and hot gas and its origin in far-UV illuminated shocks
Agata Karska, Michael J. Kaufman, Lars E. Kristensen +11
Recent observations from Herschel allow the identification of important mechanisms responsible for the heating of gas surrounding low-mass protostars and its subsequent cooling in…
The VLA Nascent Disk And Multiplicity Survey of Perseus Protostars (VANDAM). III. Extended Radio Emission from Protostars in Perseus
Łukasz Tychoniec, John J. Tobin, Agata Karska +8
Centimeter continuum emission from protostars offers insight into the innermost part of the outflows, as shock-ionized gas produces free-free emission. We observed a complete popul…
