ALMA high resolution observations of Betelgeuse: Persistent structure spanning the inner atmosphere
W. R. F. Dent, A. M. S. Richards, G. M. Harper +2
The extended atmosphere of red supergiants (RSGs) forms an important link in the process of mass loss and the subsequent enrichment of the interstellar medium. Large-scale convecti…
New Spatially Resolved Observations of Betelgeuse from the VLA and ALMA: Evidence for Atmospheric Perturbations from a Close Companion
L. D. Matthews, A. K. Dupree, A. M. S. Richards +1
We present new spatially resolved observations of the red supergiant Betelgeuse ( Orionis) at seven frequencies: 22 GHz (1.36cm); 44 GHz (6.8mm); 107 GHz (2.8mm); 136 G…
Measuring Magnetic Fields Near and Far with the SKA via the Zeeman Effect
Timothy Robishaw, Marta Nowotka, Tao-Chung Ching +7
Zeeman splitting in spectral lines -- both in emission and absorption -- provides direct estimates of magnetic field strength and direction in magnetized gas in our own Milky Way a…
