Description
V4046 Sgr is a close binary with accretion signature.
GSC 07396-00759 is instead a very active but not accreting M1-type star.
These three form a dynamically bound system, likely member of the Beta Pictoris Moving Group.
Although V4046 Sgr is surrounded by a gas-rich disk, the characteristics of the newly detected GSC disk all together tend to favor an evolved/debris disk nature over a primordial/gas-rich disk.
This makes the system composed of V4046 Sgr and GSC 07396-00759 an interesting laboratory for studying the different evolutionary timescales of coeval disks.
