Feedback of molecular outflows from protostars in NGC 1333, revealed by Herschel and Spitzer spectro-imaging observations
Odysseas Dionatos, Lars. E. Kristensen, Mario Tafalla +2
Large scale spectral maps of star forming regions enable the comparative study of the gas excitation around an ensemble of sources at a common frame of reference, providing direct…
Infrared and sub-mm observations of outbursting young stars with Herschel and Spitzer
Andreas Postel, Marc Audard, Eduard Vorobyov +3
Episodic accretion plays an important role in the evolution of young stars. Although it has been under investigation for a long time, the origin of such episodic accretion events i…
Consistent dust and gas models for protoplanetary disks IV. A panchromatic view of protoplanetary disks
O. Dionatos, P. Woitke, M. Guedel +17
Consistent modeling of protoplanetary disks requires the simultaneous solution of both continuum and line radiative transfer, heating/cooling balance between dust and gas and, of c…
Discovery of a primordial water reservoir in the envelope of HH211
Odysseas Dionatos
We report on the detection of a rich water reservoir in the protostellar envelope of the Class 0 source HH211. In striking contrast to all other molecules detected with Herschel/PA…
ALMA detects a radial disk wind in DG Tau
M. Guedel, C. Eibensteiner, O. Dionatos +7
Aims: We aim to use the high spatial resolution of the Atacama Large Millimeter/submillimeter Array (ALMA) to map the flow pattern of molecular gas near DG Tau and its disk, a youn…
Herschel spectral-line mapping of the HH211 protostellar system
Odysseas Dionatos, Tom Ray, Manuel Guedel
(Abridged) Mid- and far-infrared observations of the environment around embedded protostars reveal a plethora of high excitation molecular and atomic emission lines. In this work w…
The chemistry of episodic accretion in embedded objects. 2D radiation thermo-chemical models of the post-burst phase
Ch. Rab, V. Elbakyan, E. Vorobyov +7
Episodic accretion is an important process in the evolution of young stars and their environment. The observed strong luminosity bursts of young stellar objects likely have a long…
The feedback of atomic jets from embedded protostars in NGC 1333
Odysseas Dionatos, Manuel Güdel
Star-formation feedback onto the parent cloud is conventionally examined through the study of molecular outflows. Little is however known on the effect that atomic ejecta, tracing…
Warm gas towards young stellar objects in Corona Australis - Herschel/PACS observations from the DIGIT key programme
Johan E. Lindberg, Jes K. Jørgensen, Joel D. Green +5
The effects of external irradiation on the chemistry and physics in the protostellar envelope around low-mass young stellar objects are poorly understood. The Corona Australis star…
