Title: A simple 3D astrophysical nebula model for nova V392 Per. Author: L. Hambalek, AISAS Abstract: During our investigation of the outburst of V392 Per in 2018, we have investigated the spectral line profiles evolving in time with great temporal coverage. The profile shape was analyzed to pair different parts of emissions and absorptions with physical nebular objects present in the system at that time. In order to characterize the geometry, we have applied 3D-modelling of surfaces with their simple physical parameters to reproduce the observed spectral features. We have used a specialized software for this, which may be of use to some colleagues. We present results of this modelling.
