Hsiang-Chih Hwang

"Widely separated binary systems take more than a thousand years to complete a single orbit, making it challenging to measure the eccentricity of an individual system. Instead, Hsiang-Chih Hwang used a statistical technique to study nearly a million binary systems at once."

“We can see the unseen. An astonishing deep-field image of crashing galaxies and bygone nebulae. A glimpse at what the death of our own sun might look like. Baby stars being born perched on cosmic cliffs. The first photographs of the JWST are breathtaking, and they will dramatically change how we understand the universe."

"As Chris Hamilton (Institute for Advanced Study) explains in a recent research article, understanding the current orbits of binary stars in the Milky Way requires separating the effects of nature (the eccentricities that the binary systems are born with) and nurture (the outside gravitational effects of passing stars and the background galactic pull)."
