Spectral analysis of the early phase of Nova Del 2013

通过机会目标计划，我们获得了Nova Del 2013（V339 Del，PNV J20233073+2046041）在光学区的高分辨率TIGRE光谱。我们计划用PHOENIX/1D NLTE nova模型大气分析光学厚和早期过渡阶段的光谱。分析将提供若干时期的有效温度、密度分布、速度和丰度。 此外，我们计划使用2能级原子近似的参数化3D线形成模型来模拟强线轮廓中明显的子结构。

We have obtained a number of high-resolution TIGRE spectra of Nova Del 2013 (V339 Del, PNV J20233073+2046041) in the optical region through a target of opportunity program. We plan to analyse the spectra in the optically thick and early transition phases with PHOENIX/1D NLTE nova model atmospheres. The analysis will provide the effective temperatures, density profiles, velocities and abundances for a number of epochs. In addition, we plan to model the sub-structure apparent in the profiles of strong lines with parameterized 3D line formation models using a 2 level atom approximation.
