Kornmesser) Using this approach, an international team of astronomers headed by a researcher from Queen s University Belfast s Astrobiology Center used the Subaru telescope to look for chemical signatures in WASP-33b s atmosphere. They discovered hydroxyl, a one-oxygen, one-hydrogen atom molecule (abbreviated as OH). If it reacts with water vapor and carbon monoxide, hydroxyl is expected to play a significant role in the chemical composition of WASP-33b s atmosphere. Dr. Stevanus Nugroho, the lead researcher at Queen s University Belfast, said, This is the first time OH has been found in the atmosphere of a world outside of our Solar System. It demonstrates that astronomers can not only find this molecule in exoplanet atmospheres but also that they can begin to comprehend the composition of this planetary population in greater detail. ....

Image credit Astrobiology Center An international collaboration of astronomers led by a researcher from the Astrobiology Center and Queen’s University Belfast, and including researchers from Trinity College Dublin, has detected a new chemical signature in the atmosphere of an extrasolar planet (a planet that orbits a star other than our Sun). The hydroxyl radical (OH) was found on the dayside of the exoplanet WASP-33b. This planet is an “ultra-hot Jupiter”, a gas-giant planet orbiting its host star much closer than Mercury orbits the Sun and therefore reaching atmospheric temperatures of more than 2,500°C (hot enough to melt most metals). ....
First ever hydroxyl radical detected in ‘ultra-hot Jupiter’ atmosphere Artist’s impression of an ultra-hot Jupiter exoplanet, WASP-33b. Image: Astrobiology Center Astronomers used a new instrument to detect hydroxyl radical in the atmosphere of WASP-33b, the exoplanet known as ‘ultra-hot Jupiter’. An international team of astronomers have detected a new chemical signature in the atmosphere of an exoplanet. The team, which includes researchers from Trinity College Dublin and Queen’s University Belfast, found the first direct evidence of a hydroxyl radical (OH) in the atmosphere of a planet outside the solar system. An OH is a type of free radical and the neutral form of the hydroxide ion. It is a highly reactive species that attack most of the organic molecules. ....
