Researchers at Cornell University in the USA have discovered a unique temperature-sensitive molecule in the atmosphere of a hot exoplanet known as WASP-31b, located approximately 1,252 light years from Earth. According to the researchers, the molecule, called chromium hydride (CrH), has previously only been observed in sunspots. However, it is abundant within the temperature range of 925 to 1,725°C and exhibits exceptional sensitivity to temperature variations. Chromium hydride is often referred to as a ‘thermometer for stars’ due to its temperature sensitivity and has been used to measure the temperatures of brown dwarfs and cool stars.
