A new study has confirmed that the planet 40 Eridani Ab, also known as Vulcan from the Star Trek universe, does not exist. The initial detection was likely due to stellar activity rather than a planet. This finding highlights the challenges in distinguishing planetary signals from stellar behavior, but also advances methods that could help discover real planets in habitable zones.
The exoplanet HD 26965 b, once thought to resemble Star Trek's Vulcan, has been debunked as an illusion caused by the natural jitters of its parent star, Keid. New high-precision measurements from NASA's NEID instrument revealed that the supposed planetary signal was actually due to surface activity on Keid, not an orbiting planet. This finding highlights the importance of advanced detection methods in distinguishing real exoplanets from stellar noise.
Our Solar System is unique compared to the thousands of exoplanets discovered so far, leading some to believe that it could be an outlier in the galaxy. Most exoplanets discovered are not conducive to life due to their size and proximity to their stars. Exoplanet science is limited by our technology and our imagination, and there could be many more types of planets out there that we cannot currently detect. As technology advances, we may discover thousands of worlds hidden from our current view, and our understanding of exoplanets may change drastically.
An international team of astronomers has discovered a new multiplanetary circumbinary system, the second-ever found. The newly discovered planet, BEBOP-1c, orbits around two stars in the center, and has a mass 65 times larger than Earth. The team used the radial-velocity method to detect the planet, and although they could not measure the mass of the previously discovered planet, TOI-1338b, they were able to place strict upper limits on its mass. Circumbinary planets are rare but important in understanding planet formation.
The exoplanet 40 Eri b, previously thought to be the real-life version of the fictional planet Vulcan from Star Trek, has been disproved by a new study. The gravitational pull thought to be caused by the planet was actually caused by the star's surface activity. The radial velocity method used to detect exoplanets has limitations in detecting smaller exoplanets and those orbiting further away. While there may be other planets orbiting 40 Eridani A, none are currently suspected.
