About this image

Menkalinan (beta Auriga) is an eclipsing spectroscopic binary consisting of two very similar A type stars with a period of ~4 days. On subsequent nights the Si lines show as either one or two components as the two stars move either across the line of sight to the observer or towards/away from the observer. The positive going lines in the spectrum are calibration lines from a Ne lamp placed in front of the objective lens of the telescope.
