First detection of THz water maser in NGC7538-IRS1 with SOFIA and new 22 GHz e-MERLIN maps
F. Herpin, A. Baudry, A. M. S. Richards +7
The formation of massive stars is still not well understood. Accumulating a large amount of mass infalling within a single entity in spite of radiation pressure is possible if, amo…
Magnetic field in IRC+10216 and other C-Rich Evolved Stars
A. Duthu, F. Herpin, H. Wiesemeyer +3
During the transition from the Asymptotic Giant Branch (AGB) to Planetary Nebulae (PN), the circumstellar geometry and morphology change dramatically. Another characteristic of thi…
Magnetically aligned dust and SiO maser polarization in the envelope of the red supergiant VY CMa
W. H. T. Vlemmings, T. Khouri, I. Marti-Vidal +9
We use Atacama Large Millimeter/submillimeter Array Band 5 science verification observations of the red supergiant VY CMa to study the polarization of SiO thermal/masers lines and…
Simultaneous 183 GHz H2O Maser and SiO Observations Towards Evolved Stars Using APEX SEPIA Band 5
E. M. L. Humphreys, K. Immer, M. D. Gray +10
We investigate the use of 183 GHz H2O masers for characterization of the physical conditions and mass loss process in the circumstellar envelopes of evolved stars. We used APEX SEP…
