New Delhi, Aug 29 (PTI) The presence of a rare, temperature-sensitive molecule, detected in an exoplanet's atmosphere, has raised researchers' hopes of using it to determine temperatures on and other characteristics of similar exoplanets.
The molecule, chromium hydride (CrH) and sometimes referred to as a "thermometer for stars", has previously proved its usefulness in determining temperatures of certain types of stars such as cool stars and brown dwarfs.
This is because the hydride molecule is abundant only between 1,200-2,000 Kelvin (925-1725 degrees Celsius), according to astronomer Laura Flagg, a research associate in the College of Arts and Sciences (A&S) at Cornell University, US.
