Scientists discover planet An extrasolar system with an unusually fast orbit of 3.2 days around an ancient star 725 light-years from Earth, a team from the Indian Physical Research Laboratory (PRL) in Ahmedabad spent three months measuring the gas giant’s orbit.

The project leader, Professor Abhijit Chakraborty, said that the new exoplanet, called TOI-1789b, is orbiting very close to a developing or aging star.

The team discovered the world, which is 1.4 times larger than Jupiter and 70 percent by its mass, using the Optical Spectroradiometer (PARAS) on the telescope at Mount Abu Observatory.

The astronomers behind the discovery explained that the star’s bloated nature, caused by the staggering temperatures of 3,140 degrees Fahrenheit, and orbit around a star near the end of its life, made it important to study.

PARAS, India’s first fiber-optic spectrometer, measures the wavelength of light sources and can be used to detect the mass of an exoplanet.

The PRL team spent three months studying the hot space world, from December 2020 to March 2021, in order to understand its size and orbit.

TOI-1789b completes one orbit of its star TOI-1789 every 3.2 days, which is by comparison much less than the 88 days it takes Mercury to orbit the sun.
