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…
Shocks and UV radiation around low-mass protostars: the Herschel-PACS legacy
Agata Karska, Michael J. Kaufman, Lars E. Kristensen +1
Far-infrared spectroscopy reveals gas cooling and its underlying heating due to physical processes taking place in the surroundings of protostars. These processes are reflected in…
Origin of warm and hot gas emission from low-mass protostars: Herschel-HIFI observations of CO J=16-15. I. Line profiles, physical conditions, and H2O abundance
L. E. Kristensen, E. F. van Dishoeck, J. C. Mottram +18
(Abridged) Through spectrally unresolved observations of high-J CO transitions, Herschel-PACS has revealed large reservoirs of warm (300 K) and hot (700 K) molecular gas around low…
Herschel observations of the circumstellar environment of the two Herbig Be stars R Mon and PDS27
M. J. Jiménez-Donaire, G. Meeus, A. Karska +4
We report and analyse FIR observations of two Herbig Be stars, R Mon and PDS 27, obtained with Herschel's instruments PACS and SPIRE. We construct SEDs and derive the infrared exce…
Oxygen budget in low-mass protostars: the NGC1333-IRAS4A R1 shock observed in [OI] at 63 um with SOFIA-GREAT
L. E. Kristensen, A. Gusdorf, J. C. Mottram +5
In molecular outflows from forming low-mass protostars, most oxygen is expected to be locked up in water. However, Herschel observations have shown that typically an order of magni…
Outflows, infall and evolution of a sample of embedded low-mass protostars. The William Herschel Line Legacy (WILL) survey
J. C. Mottram, E. F. van Dishoeck, L. E. Kristensen +22
[Abridged] We present spectroscopic observations in HO, CO and related species with \textit{Herschel} HIFI and PACS, as well as ground-based follow-up with the JCMT and APEX…
