The sub-millimetre evolution of V4334 Sgr (Sakurai's Object)
A. Evans, T. R. Geballe, V. H. Tyne +3
We report the results of monitoring of V4334 Sgr (Sakurai's Object) at 450 microns and 850 microns with SCUBA on the James Clerk Maxwell Telescope. The flux density at both wavelen…
The Li Overabundance of J37: Diffusion or Accretion?
J. F. Ashwell, R. D. Jeffries, B. Smalley +3
In September 2002 the discovery of a super Li-rich F-dwarf (J37) in NGC 6633, an iron poor analogue of the better studied Hyades and Praecepe open clusters, was announced. This uni…
Observations of convection in A-type stars
Barry Smalley
Convection and turbulence in stellar atmospheres have a significant effect on the emergent flux from A-type stars. The recent theoretical advancements in convection modelling have…
Discovery of multiple shells around V838 Monocerotis
Jacco Th. van Loon, A. Evans, Mark T. Rushton +1
We report the discovery of multiple shells around the eruptive variable star V838 Mon. Two dust shells are seen in IRAS and MSX images, which themselves are situated in a shell of…
Warm high velocity CO in the wind of Sakurai's Object (= V4334 Sgr)
S. P. S. Eyres, T. R. Geballe, V. H. Tyne +3
We present UKIRT UIST spectra of Sakurai's Object (=V4334 Sgr) showing CO fundamental band absorption features around 4.7 microns. The line-centres are at heliocentric radial veloc…
CO bands in V4334 Sgr (Sakurai's Object): the 12C/13C ratio
Ya. V. Pavlenko, T. R. Geballe, A. Evans +4
We present the results of our analysis of a high resolution (R ~ 30000) infrared spectrum of V4334 Sgr (Sakurai's Object) around the first overtone CO bands, obtained in 1998 July.…
