Multi-site campaign for transit timing variations of WASP-12 b: possible detection of a long-period signal of planetary origin

Abstract: Aims. The transiting planet WASP-12 b was identified as a potential target for transit-timing studies because a departure from a linear ephemeris has been reported in the literature. Such deviations could be caused by an additional planet in the system. We attempt to confirm the claimed variations in transit timing and interpret their origin. Methods. We organised a multi-site campaign to observe transits by WASP-12 b in three observing seasons, using 0.5-2.6-metre telescopes. Results. We obtained 61 transit l… Show more

“…To limit the sample to the most reliable data, we considered only complete transit light curves that were acquired with telescopes with mirrors greater than 1 m. In addition to data from Maciejewski et al (2011) and Maciejewski et al (2013), we used photometric time series from Copperwheat et al (2013), Chan et al (2011), Cowan et al (2012), and Stevenson et al (2014).…”

“…This assumption seems to be valid because such distant companions do not significantly influence the dynamics of WASP-12b, HD 189733b, and their possible satellites. Maciejewski et al (2013) speculated that the WASP-12 system contains an additional planet, WASP-12c, with a mass of approximately 0.098 MJup, a semi-major axis of 0.0507 au, and an eccentricity of 0.284. With the presence of a second planet, WASP-12b would have an eccentricity of e ≈ 0.0447.…”
