Astronomers have found this alien planet through its unique star that wobbles as it moves through space. Know details here.
For the first time, an exoplanet around a star in a binary system has been described in three dimensions. The odd fact is that the planet orbits its star at a different angle, and scientists think the deflection could provide clues to how planets form in a binary system. The exoplanet called GJ 896Ab is located 20.3 light-years away The eartha space.com report mention.
With the aid of optical observations stored from 1941 to 2017 and additional data from 2006 to 2011 collected by the Very Long Base Array (VLBA), a network of 10 Radio telescope extended on USAastronomers were able to track the motion of the binary system star space system. In 2020, researchers used VLBA to record new observation.
The star GJ 896A appears to oscillate along its path as it travels through space, according to the scientists, who are led by Salvador Curiel of the National Autonomous University of Mexico (UNAM), according to scientists. ). An orbiting planet 2.3 times the mass of Jupiter, completing one orbit every 284.4 Earth days, is responsible for this wobble. The oscillations of the star are the result of its motion around the central center of mass, which is the common center of mass between the star and the planet.
Astrometry is the process of determining changes in a star’s motion as it moves through space. Since astronomers can clearly see the fluctuations and directions of the orbits, a planetary system with more than one star can only explain its orbit in three dimensions by astronomical measurement.
It is interesting to note that the plane of the planet’s orbit is 148 degrees away from the orbital plane of the two stars.
Do you know?
Only 4% of known exoplanets have been found in binary star systems. This low percentage is partly due to the difficulty of finding planets in binary, but also because models indicate that the presence of a companion star can shorten and weaken a disk forming planets.
