High-Velocity Bullets from V Hydrae, an AGB Star in Transition: Ejection History and Spatio-Kinematic Modeling
Samantha Scibelli, Raghvendra Sahai, Mark Morris
The carbon star V Hydrae (V Hya) provides new insight into the nature of the launching mechanism of jet-like outflows that are believed to be the cause of the poorly understood tra…
SiS in the circumstellar envelope of IRC +10126: maser and quasi-thermal emission
Y. Gong, C. Henkel, J. Ott +6
We present new Effelsberg-100 m, ATCA, and VLA observations of rotational SiS transitions in the circumstellar envelope (CSE) of IRC +10216. Thanks to the high angular resolution a…
An Apparent Precessing Helical Outflow from a Massive Evolved Star: Evidence for Binary Interaction
Ryan M. Lau, Matthew J. Hankins, Terry L. Herter +3
Massive, evolved stars play a crucial role in the metal-enrichment, dust budget, and energetics of the interstellar medium, however, the details of their evolution are uncertain be…
Old supernova dust factory revealed at the Galactic center
Ryan M. Lau, Terry L. Herter, Mark R. Morris +2
Dust formation in supernova ejecta is currently the leading candidate to explain the large quantities of dust observed in the distant, early Universe. However, it is unclear whethe…
Dusty Cradles in a Turbulent Nursery: The Sgr A East HII Region Complex at the Galactic Center
Ryan Lau, Terry Herter, Mark Morris +1
We present imaging at 19, 25, 31, and 37 μm of the compact HII region complex G-0.02-0.07 located 6 pc in projection from the center of the Galaxy obtained with SOFIA using FORCAST…
Detailed molecular observations toward the Double Helix Nebula
K. Torii, R. Enokiya, M. R. Morris +3
The Double Helix Nebula (DHN), located 100 pc above Sgr A* in the Galactic center (GC), is a unique structure whose morphology suggests it is a magnetic feature (Morris, Uchida & D…
