Scientists use Kepler telescope data to discover new multipolar systems

BingMag.com Scientists use Kepler telescope data to discover new multipolar systems

Astronomers using photometric data from NASA's Kepler telescope mission 2 have identified 747 potential planets and 57 multi-planetary systems with planet-like planets. Of these, 366 were not even previously identified, including a multipolar system and a system that has two gas giants with short rotation periods.

Professor Eric Petigura "The discovery of hundreds of new extrasolar planets is in itself a remarkable achievement, but what makes this remarkable is how it sheds light on the characteristics of the population of extrasolar planets in general," said Erik Petigura, an astronomer at the University of California School of Physics and Astronomy. One of the challenges of identifying new extrasolar planets is that the reduction in stellar luminosity may have been caused by another astrophysical instrument or source that exhibits signs of a planet. Determining which possible option needs further investigation, which has traditionally been very time-consuming, can only be done by visual inspection.

But the planet-detection algorithm developed by Professor Pettigora and colleagues Which signal indicates the planets and which is just a noise. Thus, the data of the completed mission of the Kepler space telescope was re-read.

In this new study, the results of which are the results of the entire Kepler/K2 mission data set in the Astronomical Journal ) Analyzed more than 800 million images of stars over 500 terabytes to make a list that will soon be included in NASA's main archive of extrasolar planets. In addition to the 366 new planet nominees, the list includes 381 other previously identified planets.

The findings could be an important step in helping astronomers figure out what kind of stars are likely to have planets orbiting them, as well as what the blocks needed to form a successful planet show. To understand this, we need to look at a wide range of stars, not just stars like the Sun. Among these findings was the discovery of a planetary system with two giant gas planets. Because gas giants, like Saturn in our own solar system, are seldom found as close as their host star in this case.

We have an explanation, but these findings are especially important because they help scientists gain a more accurate understanding of the parameters of how planets and planetary systems grow. " br>> Credit: Science News
