# The Central Star of NGC 2346 as a Clue to Binary Evolution through the Common Envelope Phase

25 Nov 2019 Gómez-Muñoz M. A. Manchado A. Bianchi L. Manteiga M. Vázquez R.

We present an analysis of the binary central star of the planetary nebula NGC 2346 based on archival data from the International Ultraviolet Explorer (IUE), and new low- and high-resolution optical spectra (3700 - 7300{\AA}). By including in the spectral analysis the contribution of both stellar and nebular continuum, we reconciled long-time discrepant UV and optical diagnostics and derive $E(B-V)=0.18\pm0.01$...
