Abstract:
We report the discovery from the WASP survey of two exoplanetary
systems, each consisting of a Jupiter-sized planet transiting an 11th
magnitude (V) main-sequence star. WASP-104b orbits its star in 1.75d,
whereas WASP-106b has the fourth-longest orbital period of any planet
discovered by means of transits observed from the ground, orbiting
every 9.29d. Each planet is more massive than Jupiter (WASP-104b has a
mass of 1.27±0.05MJup, while WASP-106b has a mass of
1.93±0.08MJup). Both planets are just slightly larger than
Jupiter, with radii of 1.14±0.04 and 1.09±0.04RJup for WASP-104
and WASP-106 respectively. No significant orbital eccentricity is
detected in either system, and while this is not surprising in the
case of the short-period WASP-104b, it is interesting in the case of
WASP-106b, because many otherwise similar planets are known to have
eccentric orbits.
Description:
The stars WASP-104 and WASP-106 were observed by SuperWASP-N from 2008
to 2011, and by WASP-South from 2009 to 2010. This differential survey
photometry has been de-reddened and normalised. Further photometry was
obtained using the TRAPPIST, Euler, Liverpool and Isaac Newton
telescopes in 2013 and 2014. All these data are plotted in Figures 1
and 2.
