    Paper, Journal Article

    We report on the discovery of a hot Jupiter-type exoplanet, CoRoT-17b, detected by the CoRoT satellite. It has a mass of \(2.43\pm0.30\)\Mjup and a radius of \(1.02\pm0.07\)\Rjup, while its mean density is \(2.82\pm0.38\) g/cm\(^3\). CoRoT-17b is in a circular orbit with a period of \(3.7681\pm0.0003\) days. The host star is an old (\(10.7\pm1.0\) Gyr) main-sequence star, which makes it an intriguing object for planetary evolution studies. The planet's internal composition is not well constrained and can range from pure H/He to one that can contain \(\sim\)380 earth masses of heavier elements.
