Scientists from the Institute of Astronomy in National Autonomous University of Mexico (UNAM) I discovered a rare extrasolar planet Similar to Jupiter Orbiting a star, however, is the second time this species has been discovered.

“it’s a Jupiter And it’s nothing new, but it orbits around a very low-mass star, which is theoretically unlikely to exist, which is why it’s special, noted researcher and owner of the work, Salvador Coriel Ramirez, who explained that “most commonly, massive planets like this form around stars.” Similar to the Sun but not around low-mass stars.”

discover this Rare planet discovered by UNAM It is made possible by high-resolution radio observations made with the Very Long Basic Interferometry Array (VLBA), a system of 10 identical radio antennas, or radio telescopes, controlled by a common core and working together from different parts of the world as an instrument one.

Thanks to the technology used, called absolute astrometry and the new use of this type of discovery, it is possible to determine the orbit of planet About the star and its mass, but not its density, which is necessary to know whether a planet is gaseous or rocky, however, Coriel Ramirez said that it is definitely gas planet.

“By performing a simultaneous analysis of the orbital motion of the binary system and the orbital motion of the planet around the host star, we were able to determine the three-dimensional motion of the entire system, the masses of both the stars and the universe,” University scientist pointed out.

IA postdoctoral researcher and co-worker, Gisela Ortiz-Leon, noted that This is the second detection of an exoplanet using radio astrometry.

Coriel Ramirez multiplied it To date, more than five thousand exoplanets have been found.but This is the second time it has been recognized by radio telescopes using astronomy technology. Observations using the VLBA allowed indirect detection of Jupiter associated with a red low-mass star.
