LMC68 Near-Infrared Spectra
This graph shows the near-infrared spectra of LMC68, obtained 8.58 days after the eruption with the Carnegie Institution’s Magellan Baade Telescope (black), and 22.49 days after with the Gemini South telescope (red), one half of the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab. The ionized silicon emission around 1.4 microns dominates both spectra. Apparent emission features around 1.8-2 microns are a result of contamination from Earth’s atmosphere.
This graph is adapted from Figure 2 in the paper titled “Near-infrared spectroscopy of the LMC recurrent nova LMCN 1968-12a” appearing in the Monthly Notices of the Royal Astronomical Society.
