Who is David Charbonneau?

David Charbonneau is a Professor of Astronomy at Harvard University. His research focuses on the development of novel techniques for the detection and characterization of planets orbiting nearby, Sun-like stars. These distant worlds are called exoplanets.

As a graduate student in 1999, he used a 4-inch telescope to make the first detection of an exoplanet eclipsing its parent star, which yielded the first ever constraint on the composition of a planet outside the Solar system. Charbonneau was a founding member of the Trans-Atlantic Exoplanet Survey, which used a worldwide network of humble automated telescopes to survey hundreds of thousands of stars to detect 5 more exoplanets by this technique. Charbonneau also pioneered the use of space-based observatories to undertake the first studies of the atmospheres of these distant worlds: In 2001 he used the Hubble Space Telescope to study directly the chemical make-up of the atmosphere enshrouding one of these exoplanets, and in 2005, he led the team that used the Spitzer Space Telescope to made the first direct detection of the light emitted by an exoplanet.
