SPECTRAL BEHAVIORS OF Hβ LINE OF CH CYGNI IN A QUIESCENT PHASE

SPECTRAL BEHAVIORS OF Hβ LINE OF CH CYGNI IN A QUIESCENT PHASE

We analyzed the high resolution H,6 line spectra of CH Cygni obtained at the Bohyunsan Astronomical Observatory (BOAO) on April 2004. The temporal changes in the Hβ line profiles are reported. We obtained the equivalent widths of the Gaussian components. Using this we estimated the length of the gas...

Zusammenfassung:We analyzed the high resolution H,6 line spectra of CH Cygni obtained at the Bohyunsan Astronomical Observatory (BOAO) on April 2004. The temporal changes in the Hβ line profiles are reported. We obtained the equivalent widths of the Gaussian components. Using this we estimated the length of the gaseous nebula which emits the Hβ line and the mass loss rate from the star.
