Astronomers characterize two 'super-Earths' in a distant planetary system
May 16, 2017 by Tomasz Nowakowski report
(Phys.org)—An international team of astronomers led by Eike W. Guenther of the Thuringian State Observatory in Tautenburg, Germany, has characterized two "super-Earth" exoplanets orbiting a distant star designated K2-106, determining their size, mass and density. The new findings were presented in a paper published May 11 on the arXiv pre-print server.
Located approximately 825 light years away from the Earth, K2-106 is a 5 billion-year-old star of spectral type G5. With a radius of about 0.83 solar radii, the star is 7 percent less massive than the sun. In 2016, researchers detected two planets transiting this star with orbital periods of 0.57 and 13.3 days.
