New submillimetre HCN lasers in carbon-rich evolved stars
W. Yang, K. T. Wong, H. Wiesemeyer +6
Strong laser emission from hydrogen cyanide (HCN) at 805 and 891 GHz has been discovered towards carbon-rich (C-rich) AGB stars, originating from the Coriolis-coupled system betwee…
DEATHSTAR: Nearby AGB stars with the Atacama Compact Array I. CO envelope sizes and asymmetries: A new hope for accurate mass-loss-rate estimates
S. Ramstedt, W. H. T. Vlemmings, L. Doan +16
This is the first publication of the DEATHSTAR project. The goal of the project is to reduce the uncertainties of observational estimates of mass-loss rates from Asymptotic Giant B…
Inner dusty envelope of the AGB stars W~Hydrae, SW\,Virginis, and R~Crateris using SPHERE/ZIMPOL
T. Khouri, W. H. T. Vlemmings, C. Paladini +8
Stars with initial masses between and 8~ present copious mass loss during the asymptotic giant branch (AGB) at the end of their lives. The accepted mass-loss mec…
Pulsation-triggered dust production by asymptotic giant branch stars
Iain McDonald, Elvire de Beck, Albert A. Zijlstra +1
Eleven nearby (<300 pc), short-period (50-130 days) asymptotic giant branch (AGB) stars were observed in the CO J = (2-1) line. Detections were made towards objects that have evide…
Sulphur-bearing molecules in AGB stars II: Abundances and distributions of CS and SiS
T. Danilovich, S. Ramstedt, D. Gobrecht +3
We surveyed 20 AGB stars of different chemical types using the APEX telescope, and combined this with an IRAM 30 m and APEX survey of CS and SiS emission towards over 30 S-type sta…
Sulphur-bearing molecules in AGB stars I: The occurrence of hydrogen sulfide
T. Danilovich, M. Van de Sande, E. De Beck +4
Through a survey of (sub-)millimetre emission lines of various sulphur-bearing molecules, we aim to determine which molecules are the primary carriers of sulphur in different types…
