The spectrum of VY Canis Majoris in 2000 February.
WALLERSTEIN G. and GONZALEZ G.
Abstract (from CDS):
We present the current (2000 February) status of the optical spectrum of the irregularly variable M supergiant VY CMa, based on high-resolution CCD spectra. The emission spectrum is largely unchanged over the past 43 yr, with low-lying atomic lines as well as the molecules TiO and ScO in emission. Tables of observed wavelengths for both identified and unidentified lines are presented.
