Characterization of Low-mass, Wide-separation Substellar Companions to Stars in Upper Scorpius: Near-infrared Photometry and Spectroscopy

François-René Lachapelle, David Lafrenière, Jonathan Gagné +4

We present new 0.9-2.45 $\mu$m spectroscopy ($R\sim 1000$), and $Y$, $J$, $H$, $K_s$, $L^{\prime }$ photometry, obtained at Gemini North, of three low-mass brown dwarf companions on wi…
