DOI: 10.1093/mnras/stab3772
Abstract: We present multi-epoch optical and near-infrared observations of the highly reddened, Fe ii class slow nova V2891 Cygni. The observations span 15 months since its discovery. The initial rapid brightening from quiescence, and the presence of… read more here.

DOI: 10.1093/mnras/sty2239
Abstract: We present a high-resolution (R ≃ 20 000) near-infrared (9100–13 500A) long-slit spectrum of P Cygni obtained with the newly commissioned WINERED spectrograph in Japan. In the obtained spectrum, we have found that the velocity… read more here.
