UCLA professor Benjamin Zuckerman coauthored a paper published in Astrophysical Journal on the study of the massive, dusty disk around 49 CETI.

Discovery of the Star with the Shortest Known Orbit around Our Black Hole
(2012-10-05)
|
|
The UCLA Galactic Center Group discovered a star orbiting the supermassive black hole in the center of the Milky Way galaxy with the shortest known orbital period - 11.5 years! Such stars, with their complete orbits observed, can not only provide a means for determining black hole mass but also be used to test general relativity. Their research is being published Oct 5 in the journal Science.
