Do all stars orbit around the black hole in the same plane? Or some stars can have the same orbital radius but slightly different orbital inclinations?
I do not know. It appears to me: Hypervelocity stars can have trajectories or orbits unrelated to the center of mass of a galaxy. Per the last paper cited above.Are there stars just following a galaxy, not orbiting a center?
Inclination refers to the angle at which a star's orbital plane is tilted relative to the plane of the Milky Way. This angle can range from 0 degrees (perfectly aligned with the Milky Way's plane) to 90 degrees (orbiting perpendicular to the Milky Way's plane).
Inclinations can be measured using various techniques, such as astrometry (measuring the precise position and motion of stars), spectroscopy (analyzing the light spectra of stars), and gravitational lensing (observing how a star's light is bent by the gravity of other objects). These methods allow scientists to determine a star's orbital path and its angle of inclination.
The inclinations of star orbits can be influenced by a variety of factors, including the star's initial conditions (such as mass and velocity), interactions with other stars or celestial objects, and the overall gravitational field of the Milky Way. Additionally, the inclinations of stars in the same region of the Milky Way may be more similar due to their shared history and formation processes.
Studying the inclinations of star orbits can provide valuable insight into the formation and evolution of the Milky Way galaxy. By understanding the orbital patterns and inclinations of stars, scientists can better understand the dynamics and structure of our galaxy and how it has changed over time.
Yes, there are some observed trends in the inclinations of star orbits in the Milky Way. For example, stars in the outer regions of the galaxy tend to have higher inclinations compared to stars closer to the center. This is likely due to the influence of the galactic bar and the overall gravitational potential of the Milky Way.
