The ALMA-PILS survey: Gas dynamics in IRAS 162932422 and the connection between its two protostars
M. H. D. van der Wiel, S. K. Jacobsen, J. K. Jørgensen +10
[Abridged] The majority of stars form in binary or higher order systems. The Class 0 protostellar system IRAS16293-2422 contains two protostars, 'A' and 'B', separated by ~600 au a…
The organic chemistry in the innermost, infalling envelope of the Class 0 protostar L483
Steffen K. Jacobsen, Jes K. Jørgensen, James Di Francesco +3
Context: The protostellar envelopes, outflow and large-scale chemistry of Class~0 and Class~I objects have been well-studied, but while previous works have hinted at or found a few…
The ALMA-PILS survey: 3D modeling of the envelope, disks and dust filament of IRAS 16293-2422
S. K. Jacobsen, J. K. Jørgensen, M. H. D. van der Wiel +8
Context. The Class 0 protostellar binary IRAS 16293-2422 is an interesting target for (sub)millimeter observations due to, both, the rich chemistry toward the two main components o…
The ALMA-PILS survey: First detections of ethylene oxide, acetone and propanal toward the low-mass protostar IRAS 16293-2422
J. M. Lykke, A. Coutens, J. K. Jørgensen +14
One of the open questions in astrochemistry is how complex organic and prebiotic molecules are formed. Aims. Our aim is to start the process of compiling an inventory of oxygen-bea…
Water around IRAS15398-3359 observed with ALMA
P. Bjerkeli, J. K. Jørgensen, E. A. Bergin +9
How protostars accrete mass is one of the fundamental problems of star formation. High column densities and complex kinematical structures make direct observations challenging and…
The ALMA Protostellar Interferometric Line Survey (PILS): First results from an unbiased submillimeter wavelength line survey of the Class 0 protostellar binary IRAS 16293-2422 with ALMA
J. K. Jørgensen, M. H. D. van der Wiel, A. Coutens +14
The inner regions of the envelopes surrounding young protostars are characterised by a complex chemistry, with prebiotic molecules present on the scales where protoplanetary disks…
The ALMA-PILS survey: First detections of deuterated formamide and deuterated isocyanic acid in the interstellar medium
A. Coutens, J. K. Jørgensen, M. H. D. van der Wiel +15
Formamide (NHCHO) has previously been detected in several star-forming regions and is thought to be a precursor for different prebiotic molecules. Its formation mechanism is st…
Using the Inclinations of Kepler Systems to Prioritize New Titius-Bode-Based Exoplanet Predictions
Timothy Bovaird, Charles H. Lineweaver, Steffen K. Jacobsen
We analyze a sample of multiple-exoplanet systems which contain at least 3 transiting planets detected by the Kepler mission ("Kepler multiples"). We use a generalized Titius-Bode…
