G. Pandey et al., THE EMISSION-LINE SPECTRUM OF THE HOT R-CORONAE-BOREALIS STAR MV SGR, Monthly Notices of the Royal Astronomical Society, 282(3), 1996, pp. 889-899
Spectra of MV Sgr obtained at CTIO in 1992 May show many emission line
s in the red. Most of the emission lines show two components with a mi
nimum 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 670
7-Angstrom resonance doublet. [O I] and [N II] emission indicate the p
resence of a nebula around the star. The radial velocity of the absorp
tion lines (Al III, Si III, N II and C II) and Fe II emission lines ag
rees with the radial velocity given by Jeffery et al.
