摘要：

Spectra of MV Sgr obtained at CTIO in 1992 May show many emission lines in the red. Most of the emission lines show two components with a minimum centred at the stellar velocity. Species represented include H, He I, Ti II and Fe II. Of special interest is emission in the Li I 6707-Å resonance doublet. [O I] and [N II] emission indicate the presence of a nebula around the star. The radial velocity of the absorption lines (AI III, Si III, N II and e II) and Fe II emission lines agrees with the radial velocity given by Jeffery et al. © 1996 RAS.
