a preliminary spectrum

Forums Variable Stars MV Lyr fading a preliminary spectrum

Robin Leadbeater

Despite poring over the radar maps looking for gaps between the rain showers I have only managed 10 min on this so far.

Only the Balmer lines in emission are clear in the noisy spectrum but it does perhaps seem to be intermediate between the low and high state spectra in the literature. Here for example in the high state from  L. Rosino et al 1993 PASP 105 51

and the low state (blue end only) from Voikhanskaia, N. F. 1988, A&A, 192, 128  

(Both low state spectra, showing interesting variation during the 0.13 day orbit)
