Description
The surroundings of the supermassive black hole at the center of our galaxy, Sagittarius A, are mostly unknown and for this reason many studies have tried to constrain the presence of an extended mass around it, with the aim of simulating either dark matter distribution or stellar clusters. However, all these works focus on spherically symmetric distributions of matter, while observations suggest that matter clusters in disks or rings around compact objects. In this talk I will present our findings regarding the effect that a planar distribution of matter will have on S-stars, compared to the spherically symmetric case. The final aim is to show whether the current upper limit on the extended mass around SgrA obtained by GRAVITY changes when a disk of matter is considered.
