Determining Stellar: Transcript
Distances Parallax Detected The Problem Faced by Astronomers cast your mind back to the 1700s and 1800s There are hundreds of thousands of stars visible through small telescopes Only a tiny fraction of them will display measureable heliocentric parallax and you dont know which they are.

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 . versus convective . blueshifts. , and wavelength variations across stellar disks.
