  • We present Gemini near-infrared adaptive optics imaging and spectroscopy of a planetary-mass candidate companion to 1RXS J160929.1–210524, a roughly solar-mass member of the 5 Myr old Upper Scorpius association. The object, separated by 2.22 -->'' or 330 AU at ~150 pc, has infrared colors and spectra suggesting a temperature of -->1800−100+200 K, and spectral type of L4 -->−2+1. The H- and K-band spectra provide clear evidence of low surface gravity, and thus youth. Based on the widely used… CONTINUE READING
