The Infrared Counterpart of the X-Ray Nova XTE J1720โ318
Abstract We report on the discovery of an infrared counterpart to the X-ray transient XTE J1720$-$318 on 2003 January 18, nine days after an X-ray outburst, and the infrared light curve during the first 130 days after the outburst. The infrared light curve shows a decline of $\sim 1.2 \,\mathrm{mag}$ โฆ
