HTTP:: Exoplanet to Be Used As a 039 Mobile Science Lab 039
--------
Some 700 light-years away from our solar system, researchers identified two exoplanets, orbiting their parent star, and influencing each other in the process. The star, dubbed HAT-P-13, is orbited by the planets HAT-P-13b and HAT-P-13c, each of which exerts a gravitational pull on the other. Now, scientists plan to use one of these bodies to effectively “X-ray†the other, and determine if it has a rocky core, and, if so, just how big it is. The larger, more massive HAT-P-13c will be used as the “mobile laboratory,†as astronomers peer at the inner workings of HAT-P-13b, Wired reports. “C is allowing us to look inside B. X-raying the planet taps into these esoteric theories that were worked out in the 1930s, but hadn’t been picked up by the extrasolar planet community,†University of California in Santa Cruz (UCSC) astronomer Greg Loughlin says. He is the co-author of a new paper detailing the initiative, which was recently submitted for publication in an upc!
oming issue of the respected scientific journal Astrophysical Journal Letters. As the two planets revolve around each other, the expert explains, they warp each others' orbits. By calculating the eccentricities that appear because of this phenomenon, mathematicians can use advanced methods to determine...
