Comparison of the LNIR spectra of large T types with low-albedo asteroids in different taxonomic types and comet 67P/C-G. (96) Aegle and (308) Polyxo (Takir & Emery 2012) represent large T types and are compared with the spectra of Jupiter Trojans (Brown 2016), (1) Ceres (De Sanctis et al. 2018), and comet 67P/C-G (Poch et al. 2020). Each spectrum was arbitrarily offset for clarity. Four vertical lines indicate the absorption bands of 2.72 µm, 3.06 µm, 3.1 µm, and 3.14 µm. The first (OH) and second (N–H) bands were detected on (1) Ceres (Carrozzo et al. 2018; De Sanctis et al. 2018), the third (N–H) band was found on Jupiter Trojans (Brown 2016), and the last band was seen on (96) Aegle (Fig. 3).
