Low-resolution near-infrared spectroscopic signatures of unresolved ultracool companions to M dwarfs

Abstract We develop a method to identify the spectroscopic signature of unresolved L-dwarf ultracool companions, which compares the spectra of candidates and their associated control stars using spectral ratio differences and residual spectra. We present SpeX prism-mode spectra (0.7–2.5 μm) for a pi...
