Abstract:
We report the discovery of the transiting exoplanets WASP-95b,
WASP-96b, WASP-97b, WASP-98b, WASP-99b, WASP-100b and WASP-101b. All
are hot Jupiters with orbital periods in the range 2.1-5.7d, masses
of 0.5-2.8MJup and radii of 1.1-1.4RJup. The orbits of
all the planets are compatible with zero eccentricity. WASP-99b
produces the shallowest transit yet found by WASP-South, at 0.4 per
cent.
The host stars are of spectral type F2-G8. Five have metallicities of
[Fe/H] from -0.03 to +0.23, while WASP-98 has a metallicity of -0.60,
exceptionally low for a star with a transiting exoplanet. Five of the
host stars are brighter than V=10.8, which significantly extends the
number of bright transiting systems available for follow-up studies.
WASP-95 shows a possible rotational modulation at a period of 20.7d.
We discuss the completeness of WASP survey techniques by comparing to
the HATnet project.
Description:
The observational and analysis techniques used here are the same as in
recent WASP discovery papers (e.g. Hellier et al.,
2012MNRAS.426..739H 2012MNRAS.426..739H, Cat. J/MNRAS/426/739).
In outline, WASP-South surveys the visible sky each clear night using
an array of 200 mm f/1.8 lenses and a cadence of ∼10-min. Transit
searching of accumulated light curves leads to candidates that are
passed to TRAPPIST (a robotic 0.6-m photometric telescope, which can
resolve blends and check that the candidate transits are planet-like),
and to the 1.2-m Euler/CORALIE spectrograph [for radial-velocity (RV)
observations]. About 1 in 12 candidates turns out to be a planet.
Higher quality transit light curves are then obtained with TRAPPIST
and with EulerCAM (Lendl et al., 2012A&A...544A..72L 2012A&A...544A..72L, Cat.
J/A+A/544/A72).
