Mark Morris. UCLA. ABSTRACT -- The . well-defined, massive disk of young stars orbiting within 0.5 pc of the Galactic black hole (GBH) is strongly tilted with respect to the Galactic plane. In the context of in situ formation mechanisms, this orientation is inherited from that of the gas disk that formed these stars on the order of 6 million years ago. The tilt can be understood by positing that clouds fall toward the GBH on near-zero angular momentum orbits and form dispersion rings as they self-intersect after . Parallax is the apparent displacement of an object against the background when seen from two different perspectives.. Definition of Parallax. To measure the distance to a star, astronomers measure the parallax shift of the star using 2 points of view that are as far apart as possible-at opposite sides of Earth’s orbit.. Soroush Sotoudeh. .
