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 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 ALMA-PILS survey: First detection of nitrous acid (HONO) in the interstellar medium
A. Coutens, N. F. W. Ligterink, J. -C. Loison +7
Nitrogen oxides are thought to play a significant role as a nitrogen reservoir and to potentially participate in the formation of more complex species. Until now, only NO, NO a…
Probing the Protosolar Disk Using Dust Filtering at Gaps in the Early Solar System
Troels Haugbølle, Philipp Weber, Daniel P. Wielandt +4
Jupiter and Saturn formed early, before the gas disk dispersed. The presence of gap-opening planets affects the dynamics of the gas and embedded solids and halts the inward drift o…
The Mass Evolution of Protostellar Disks and Envelopes in the Perseus Molecular Cloud
Bridget C. Andersen, Ian W. Stephens, Michael M. Dunham +8
In the standard picture for low-mass star formation, a dense molecular cloud undergoes gravitational collapse to form a protostellar system consisting of a new central star, a circ…
K2-291 b: A rocky super-Earth in a 2.2 day orbit
Molly R. Kosiarek, Sarah Blunt, Mercedes Lopez-Morales +43
K2-291 (EPIC 247418783) is a solar-type star with a radius of R_star = 0.899 0.034 R_sun and mass of M_star=0.934 0.038 M_sun. From K2 C13 data, we found one super-Eart…
