The continuing saga of Sakurai's object (V4334 Sgr): dust production and helium line emission

• We report further UKIRT spectroscopic observations of Sakurai's object (V4334 Sgr) made in 1999 April/May in the 1-4.75 mu m range, and find that the emission is dominated by amorphous carbon at T-d similar to 600 K. The estimated maximum grain size is 0.
