SUMMARY

There are indeed stars with highly eccentric orbits around the center of their galaxy, similar to the orbits of comets in our solar system. These stars can exhibit elliptical, parabolic, or hyperbolic trajectories and may not align with the galactic plane. Notable examples include specific black hole candidates that demonstrate these unique orbital characteristics. For further details, refer to the European Southern Observatory's press release on this topic.

PREREQUISITES
  • Understanding of stellar dynamics
  • Familiarity with orbital mechanics
  • Knowledge of galactic structures
  • Basic concepts of black holes
NEXT STEPS
  • Research the properties of black hole candidates in galactic centers
  • Study the mechanics of eccentric orbits in astrophysics
  • Explore the implications of non-aligned orbits with the galactic plane
  • Investigate the role of comets in understanding stellar orbits
USEFUL FOR

Astronomers, astrophysicists, and students interested in stellar dynamics and galactic structures will benefit from this discussion.

An interesting question has arised from one of the discussions around here: are there any stars that have a highly eccentric elliptical (or even parabolic/hyperbolic) orbit around the center of their gallaxy, somewhat like comets have in our solar system? And for that matter, are there any stars whose orbits are not aligned with the gallactic plane?

Yes, plenty. Some examples (click on the links in each website below to get more info):
