AbstractIn this Letter, we first report one unique object SDSS J0832+0643 with particular features of narrow Balmer emission lines: double-peaked narrow H alpha but single-peaked narrow H beta. The particular features cannot be expected by currently proposed kinematic models for double-peaked narrow emission lines, because the proposed kinematic models lead to similar line profiles of narrow Balmer emission lines. However, due to radiative transfer effects, the non-kinematic model can be naturally applied to well explain the particular features of narrow Balmer emission lines: larger optical depth in H alpha than 10 leads to observed double-peaked narrow H alpha, but smaller optical depth in H beta around 2 leads to observed single-peaked narrow H beta. Therefore, SDSS J0832+0643 can be used as strong evidence to support the non-kinematic model for double-peaked narrow emission lines.
