Ultraviolet Spectropolarimetry: on the origin of rapidly rotating B stars

Hillier, D. J.; Carciofi, A. C.; Nazé, Y. +12 more

UV spectroscopy and spectropolarimetry hold the key to understanding certain aspects of massive stars that are largely inaccessible (or exceptionally difficult) with optical or longer wavelength observations. As we demonstrate, this is especially true for the rapidly-rotating Be and Bn stars, owing to their high temperatures, geometric asymmetries…

A radio continuum study of NGC 2082

Filipović, M. D.; Dai, S.; Barnes, L. +2 more

We present radio continuum observations of NGC 2082 using ASKAP, ATCA and Parkes telescopes from 888 MHz to 9000 MHz. Some 20 arcsec from the centre of this nearby spiral galaxy, we discovered a bright and compact radio source, J054149.24–641813.7, of unknown origin. To constrain the nature of J054149.24–641813.7, we searched for transient events …
