Accurate Orbital Solution for the New and Metal-poor Eclipsing Binary Tycho 5227-1023-1
Accurate Orbital Solution for the New and Metal-poor Eclipsing Binary Tycho 5227-1023-1
The orbit and physical parameters of the previously unsolved double-lined eclipsing binary Tyc 5227-1023-1, discovered during the search for RR Lyr variable candidate members of the Aquarius stream, are derived using high-resolution échelle spectroscopy and photometry. A synthetic spectral analysis of both components has been performed, yielding metallicity [M/H] = …
