Astronomers discover a new planet that
Keplerd is the largest of the three planets in the Kepler system. So, we have to correct for the ones we missed.
The discoveries have been accepted for publication in an upcoming issue of The Astronomical Journal. The planet, known as KBb, could be rocky, or gas-rich, similar to Neptune. Discovery and validation of an Earth-sized planet in the four-planet system K near the resonance.
Using data from NASA's Kepler space telescope, a team of researchers detected the new Neptune-to-Saturn-size planet orbiting between two previously known planets. This change came about after a mechanical failure. Its discovery is particularly exciting because the planet's size just slightly smaller than Neptune is so rare among those beyond our solar system — known as exoplanets.
Dattilo plans to continue her work using AI for planet hunting when she enters graduate school in the fall.
Scientists discover new planet
One of the least favorable for finding planets is known as "direct imaging". The planet was discovered largely because of volunteers examining light-curve data from the Kepler with their own eyes, rather than via software. When a planet moves in front of a star, it therefore initially blocks less starlight than at the mid-time of the transit. Using data from NASA's Kepler space telescope, a team of researchers detected the new Neptune-to-Saturn-size planet orbiting between two previously known planets. They are slightly larger than Earth. An illustration of what GJ d might look like, with its M-dwarf star in the distance. Their excitement was focused on a potentially rocky super-Earth planet in the zone where liquid water could be stable on the surface. Their research was recently published in the Astronomical Journal. The discovery of the planet, another super-Jupiter with approximately nine times the mass of Jupiter, throws a cosmic spanner in our current understanding of the well-studied but largely mysterious Beta Pictoris system. To find them, the team, led by an undergraduate at UT Austin, Anne Dattilo, created an algorithm that sifts through the data taken by Kepler to ferret out signals that were missed by traditional planet-hunting methods. The new method developed by Heller and his colleagues opens up fascinating possibilities. Volunteer scientists from a citizen program named Exoplanet Explorers were able to spot the planet that software algorithms had missed. Small planets, however, present scientists with immense challenges.
This was almost shocking," said Welsh. As a consequence, the transits of planets in wide orbits occur less often, which makes their signals even harder to detect. The planets discovered this time were from Kepler's extended mission, called K2.
The transit depth went from undetectable at the beginning of the Kepler Mission to the deepest of the three planets over the span of just four years. These observations were done with the 1. The two planets Dattilo's team found "are both very typical of planets found in K2," she said.
