2021年爆发的RS Oph。光谱演化的图解图集:最初的18天

The 2021 outburst of RS Oph. A pictorial atlas of the spectroscopic evolution: the first 18 days

U. Munari, P. Valisa

摘要:

在光学波长的光谱演化的图片图集提出了2021年爆发的经常性新星RS Oph的前18天,出现高电离发射线之前。这里展示的光谱是用Asiago 1.22 m + B&C(3200-7900 Ang,2.3/pix)和Varese 0.84 m + Echelle望远镜(4250-8900,分辨率18,000)以日常节奏获得的。光谱已经在IRAF中完全校准,绝对通量和日心校正。中阶梯光谱也已被校正为大地反射。

英文摘要:

A pictorial atlas of the spectroscopic evolution at optical wavelengths is presented for the first 18 days of the 2021 outburst of the recurrent nova RS Oph, prior to the emergence of high ionization emission lines. The spectra presented here have been obtained at daily cadence with the Asiago 1.22m + B&C (3200-7900 Ang, 2.3 Å/pix) and Varese 0.84m + Echelle telescopes (4250-8900 Å, resolving power 18,000). The spectra have been fully calibrated in IRAF, absolutely fluxed, and heliocentric corrected. The Echelle spectra have been also corrected for telluric absorptions.
