YZ Ret (Nova Ret 2020)

Post by 2SPOT »

Here's a spectrum of Nova Ret 2020 (YZ Ret) at mag. V=14,2 from our setup in Chile

The spectrum shows split lines [OIII], does this mean that there is a double component?

This paper which attempts to model the line profiles shows similar shaped [OIII] and H alpha lines, with some additional higher velocity components

see fig 5 for example

Interestingly some of the spectra in this paper were taken using a LHIRES !

Hello Robin,

Thanks for the paper.
This is very interesting and shows that there are investigations to be done on this star
