Studies of Evolved Stars in the Next Decade: EAO Submillimetre Futures White Paper Series, 2019
Peter Scicluna, Hiroko Shinnaga, Jonathan Marshall +8
This white paper discusses recent progress in the field of evolved stars, primarily highlighting the contributions of the James Clerk Maxwell Telescope. It discusses the ongoing pr…
The Nearby Evolved Stars Survey: I. JCMT/SCUBA-2 Sub-millimetre detection of the detached shell of U Antliae
Thavisha E. Dharmawardena, Francisca Kemper, Sundar Srinivasan +24
We present the highest resolution single-dish submillimetre observations of the detached shell source U Antliae to date. The observations were obtained at $450~\micron$ and $850~\m…
The Sub-mm Variability of IRC+10216 and Ceti
Thavisha E. Dharmawardena, Francisca Kemper, Jan G. A. Wouterloot +3
We present the sub-mm variability of two of the most well studied AGB stars, IRC+10216 and Ceti. The data are obtained at $450~\micron$ and $850~\micron$ as part of pointing ca…
Compressed magnetic field in the magnetically-regulated global collapsing clump of G9.62+0.19
Tie Liu, Kee-Tae Kim, Sheng-Yuan Liu +22
How stellar feedback from high-mass stars (e.g., H{\sc ii} regions) influences the surrounding interstellar medium and regulates new star formation is still unclear. To address thi…
Discovery of two embedded massive YSOs and an outflow in IRAS 18144-1723
W. P. Varricatt, J. G. A. Wouterloot, S. K. Ramsay +1
Massive stars are rarely seen to form in isolation. It has been proposed that association with companions or clusters in the formative stages is vital to their mass accumulation. I…
Extended Dust Emission from Nearby Evolved Stars
Thavisha E. Dharmawardena, Francisca Kemper, Peter Scicluna +6
We present JCMT SCUBA-2 m and m observations of 14 Asymptotic Giant Branch (AGB) stars (9 O--rich, 4 C-rich and 1 S--type) and one Red Supergiant (RSG) in the Solar Nei…
