We explore the possibility that GSC 07396–00759 ( spectral type M1e ) is a widely separated ( \sim 2.82 ^ { \prime } , or projected separation \sim 12,350 AU ) companion to the “ old ” ( age \sim 12 Myr ) classical T Tauri binary system V4046 Sgr AB , as suggested by the proximity and similar space motions of the two systems . If the two systems are equidistant and coeval , then GSC 07396–00759 , like V4046 Sgr AB , must be a spectroscopic binary with nearly equal-mass components , and V4046 Sgr must be at least \sim 8 Myr old . Analysis of a serendipitous Chandra X-ray gratings spectrum and light curve as well as XMM-Newton light curves and CCD spectra of GSC 07396–00759 obtained during long exposures targeting V4046 Sgr AB reveals a relatively hard ( T _ { X } \sim 10 ^ { 7 } K ) X-ray spectrum , strong flaring , and relatively low-density plasma . These X-ray characteristics of GCS 07396–00759 are indicative of a high level of coronal activity , consistent with its apparent weak-lined T Tauri star status . Interactions between V4046 Sgr AB and GCS 07396–00759 when the two systems were more closely bound may be responsible for ( a ) their dissolution \sim 10 ^ { 6 } yr ago , ( b ) the present tight , circular orbit of V4046 Sgr AB , and ( c ) the persistence of the gaseous circumbinary disk still orbiting V4046 Sgr AB .
