Shelyak: a peculiar star

Shelyak is the second, in order of magnitude, star of Lyrae constellation: beta Lyrae. With some uncertainty in the arabic root, Shelyak meant “turtle”. It should come from mythology where Mercury was resting near the Nil and saw a turtle shell. He noticed the nice sound when he was knocking on it; he then had the idea to attach strings on the shell and created the first musical instrument: a lyrae!

but beta Lyrae is also a fascinating star. Its brightness varies over a dozen days period; this is well visible with naked eyes. But beta Lyrae spectrum reveals several emission lines. It is actually a spectroscopic binary with one star filling its Roche limits and the second one beeing a Be star: a star surrounded by a ring of material with polar jets…

Shelyak is for us a peculiar star; we studied it during several weeks. It was then natural for us to name our company Shelyak Instruments.

Founders

Shelyak Instruments has been founded by François COCHARD and Olivier THIZY, both amateur astronomers with dozens years of practice in the field. we are Passionnate, we industrialized the Lhires III in collaboration with Christian Buil and work on the manufacturing and distribution of the original kit within AUDE association.
