Oh, that's a gentle question, friend! Stars aren't forming in the galactic halo mainly because the halo contains older stars and less of the materials needed for new stars to form compared to the galaxy's disk. Remember, even in the stillness of the halo, the universe twinkles with endless possibilities elsewhere!
The collection of ancient stars found in the center of the Local Group is called the Galactic Halo. The Galactic Halo is a spherical region of space that surrounds the disk of the Milky Way galaxy. It is made up of old, metal-poor stars that are thought to have formed very early in the history of the Milky Way. The Galactic Halo is also home to globular clusters, which are dense groups of hundreds of thousands of stars. The Galactic Halo is thought to be the remnant of a smaller galaxy that merged with the Milky Way billions of years ago. The merger caused the smaller galaxy to be torn apart, and its stars were scattered into the Galactic Halo. The Galactic Halo is a very sparsely populated region of space. The stars are so far apart that they are difficult to see individually with the naked eye. However, the Galactic Halo can be seen in the night sky as a faint glow of light.
"The halo primarily contains individual old stars and clusters of old stars ("globular clusters"). It may be over 130,000 light years across. The halo also contains "dark matter," which is material that we cannot see but whose gravitational force can be measured." to shorten the answer - individual stars, clusters, and dark matter.
maybe i dont know it can be make you guess.
Halo stars are usually very old stars that do no orbit the centre of the Galaxy the same way that our Sun or other stars in a galaxy. Rather, they travel in elliptical orbits, which often take them well outside the plane of the Galaxy.
A globular cluster is a part of a galaxy, usually found in the halo surrounding the galactic center. Globular clusters are densely packed groups of thousands to millions of stars held together by gravity. They orbit the center of their host galaxy along with other components such as the spiral arms and bulge.

They orbit as stars would in any other halo. It is gravity that causes everything to orbit and "spin around" Stars can also orbit around other stars called a binary orbit.

Globular star clusters are members of the Milky Way galaxy. They are dense, spherical collections of stars that orbit the galactic center. These clusters contain thousands to millions of ancient stars and are typically found in the galactic halo.
In the Milky Way galactic halo, orbiting the galactic center in a long elliptical orbit around the galactic center
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.
Galactic rotation curves show that stars orbit the center of galaxies at velocities that do not decrease with distance from the center. This suggests that there is additional unseen mass, or dark matter, distributed throughout the galaxy's extended halo. The presence of dark matter is necessary to provide the gravitational pull required to keep stars at their observed velocities.

The Galactic halo is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars.
Stars in the middle of galaxies are usually found in the galactic disk, where there is a higher concentration of gas and dust that is conducive for star formation. Stars on the outside of galaxies are often located in the galactic halo, which is a more diffuse region that contains older stars and is further away from the dense center of the galaxy. The distribution of stars within a galaxy is influenced by factors such as gravitational interactions and the history of star formation in that region.
Palomar 1 is located in the Milky Way galaxy's halo, not in the spiral arms. It is a globular cluster, which is a spherical collection of stars orbiting the galactic core.
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.
