dc.description This is a pre-copyedited, author-produced PDF of an article accepted for publication in Monthly Notices of the Royal Astronomical Society following peer review. The version of record Barragán, O. et al. "K2-139 b: A low-mass warm Jupiter on a 29-d orbit transiting an active K0 V star" is available online at: http://doi.org/10.1093/mnras/stx3207 en_US
dc.description.abstract We announce the discovery of K2-139 b (EPIC 218916923 b), a transiting warm-Jupiter (Teq= 547± 25 K) on a 29-d orbit around an active (logR'HK=-4.46±0.06) K0V star in K2 Campaign 7.We derive the system's parameters by combining the K2 photometry with groundbased follow-up observations. With a mass of 0.387-0.033+0.075MJand radius of 0.808-0.033+0.034RJ, K2-139 b is one of the transiting warm Jupiters with the lowest mass known to date. The planetary mean density of 0.91-0.20+0.24g cm-3can be explained with a core of ~50M⊕. Given the brightness of the host star (V=11.653 mag), the relatively short transit duration (~5 h), and the expected amplitude of the Rossiter-McLaughlin effect (~25m s-1), K2-139 is an ideal target to measure the spin-orbit angle of a planetary system hosting a warm Jupiter en_US
