What do halo stars do differently from disk stars?
Halo stars are older and have lower metallicity compared to disk stars. They often have orbits that take them further away from the plane of the galaxy and they are thought to have formed through different mechanisms, such as mergers with other galaxies or early galactic collapse.
What is the difference between disk stars and halo stars?
Stars in the disk all orbit in the same direction and nearly the same plane, while halo stars have more randomly oriented orbits.Clusters of young stars are found only in the disk.Disk stars come in a broad range of masses and colors, while halo stars are mostly of low mass and red.Gas and dust are abundant in the disk but not in the halo.
How do spiral galaxies form?
Spiral galaxies form from the collapse of a protogalactic cloud. Spiral galaxies consist of three components: a rotating disk, a bulge and a halo. Spiral galaxies, like the Milky Way, owe their shape to stars inside the protogalaxy developing at different intervals. The gas between forming stars continues to be compressed, and the resulting gravitational differences manhandle the protogalaxy's stars, dust and gas. When the protogalactic cloud collapses, the stars in the bulge and halo form first. These stars have rather random orbits around the galactic center. The galactic center probably contains a supermassive black hole, which likely exerts some gravitational influence on the formation of a spiral galaxy. The remainder of the cloud forms a disk due to the conservation of angular momentum (the same effect as the spinning up of the dancer when she pulls her arms inside). This motion forces everything into a rotating disk, and additional differences in gravity build the spiral arms. Oppositely, when a protogalaxy's stars develop at the same time, you have an elliptical galaxy on your hands. The stars in the disk form later and thus the disk population of stars are younger than those in the bulge and the halo. Further, the stars in the disk rotate around the center of the galaxy in a collective, well defined way unlike the stars in the bulge and halo.
The Population II stars in your galaxy are located a in the halo but not in the disk b in neither the halo nor the disk c in both the halo and the disk d in the disk but n?

Why do planets orbit the sun at different distances?
The planets formed from a disk of gas and dust that surrounded the sun as it formed. This gas and dust clumped together to form the solar system. Two planets cannot occupy orbits that are too close together. If they do, interactions through gravity will either cause them to collide or get moved to different orbits.

How are stars in the disk of the milky way different from stars in the bulge or halo?
The ones in the bulge or halo are older star, the ones in the disk are younger.
Does the sun orbit anything?
Yes, it orbits the galactic center.The sun is one of billions of stars that comprise the Milky Way galaxy - a more or less flat circular disk of stars that rotates about it's centre. Therefore, the sun "orbit" the centre of the galaxy in a manner analogous to how the earth orbits the sun.
Why do metal-poor stars have a wider range of orbital shapes than metal-rich stars like the sun?
The oldest stars are metal poor because they formed before there had been many supernova explosions to create and scatter metals into interstellar medium. Those stars formed long ago when the galaxy was young and motions were not organized into a disk, so the stars tended to take up randomly shaped orbits, many of which are quite elongated and eccentric. Consequently, today, the most metal poor stars tend to follow the most eccentric orbits.
What other terms are used for disk herniation?
also commonly called a herniated nucleus pulposus, prolapsed disk, ruptured disk, or
