Water vapour masers in long-period variable stars IV. Mira variables RCas, oCet and RLeo
Jan Brand, Dieter Engels, Alessandra Zanichelli +1
Between 1987 and 2023 we carried out single-dish monitoring campaigns of water-maser emission at 22 GHz in the circumstellar envelopes (CSEs) of four stars: RCas, oCet, RLeo and Ch…
Recurring OH Flares towards o Ceti: I. location and structure of the 1990s' and 2010s' events
S. Etoka, E. Gerard, A. M. S. Richards +3
We present the analysis of the onset of the new 2010s' OH flaring event detected in the OH ground-state main line at 1665~MHz towards o Ceti and compare its characteristics with th…
e-MERLIN resolves Betelgeuse at wavelength 5 cm
A. M. S. Richards, R. J. Davis, L. Decin +8
Convection, pulsation and magnetic fields have all been suggested as mechanisms for the transport of mass and energy from the optical photosphere of red supergiants, out to the reg…
Evolved star water maser cloud size determined by star size
A. M. S. Richards, S. Etoka, M. D. Gray +5
Cool, evolved stars undergo copious mass loss but the details of how the matter is returned to the ISM are still under debate. We investigated the structure and evolution of the wi…
The OH Masers Towards IRAS 19092+0841
K. A. Edris, G. A. Fuller, S. Etoka +1
Context. Maser emission is a strong tool for studying high mass star forming regions and their evolutionary stages. OH masers in particular can trace the circumstellar material aro…
