(Phys.org)—Giant exoplanets,like the so-called 'hot Jupiters' that are similar in characteristics to the solar system's biggest planet and orbit very close to their host stars, are excellent targets for astronomers in their search for extrasolar worlds. The size and proximity of these planets is easy to detect as they create a large decrease in brightness when passing in front of their parent stars. Recently, and an international team of researchers has announced a discovery of five unique exoplanets,extending the catalogue of known 'hot Jupiters'. They published their findings in a paper published online on Feb. 4 in the arXiv journal.
