| Abstract: | The new spectroscopic observation of MV Sgr obtained at ESO in 1987 July shows enhanced emission lines of He I λ3889, SII] λ4068 relative to the observations discussed by Jeffreyet al. (1988). The presence of SII] λ4068 indicates the presence of planetary-nebulae-like envelope around the star. Although the radial velocity of the absorption
lines and Fe II emission lines do agree with the velocity given by Jeffreyet al., the SII] λ4068 and probably He I emission lines appear to behave differently.
Based on observations collected at the European Southern Observatory, La Silla, Chile. |
