The Circumstellar Environment of R Coronae Borealis: White Dwarf Merger or Final Helium Shell Flash?
Geoffrey C. Clayton, Ben E. K. Sugerman, S. Adam Stanford +21
In 2007, R Coronae Borealis (R CrB) went into an historically deep and long decline. In this state, the dust acts like a natural coronagraph at visible wavelengths, allowing faint…
Imaging the circumstellar dust around AGB stars with PolCor
S. Ramstedt, M. Maercker, G. Olofsson +2
The aim of this paper is to investigate how the new imaging Polarimeter and Coronograph (PolCor) at the Nordic Optical Telescope (NOT) can be used in the study of circumstellar str…
Warm water vapour in the sooty outflow from a luminous carbon star
L. Decin, M. Agundez, M. J. Barlow +34
In 2001, the discovery of circumstellar water vapour around the ageing carbon star IRC+10216 was announced. This detection challenged the current understanding of chemistry in old…
