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 2.1–5.7 d, masses of 0.5–2.8 MJup and radii of 1.1–1.4 RJup. 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 20.7 d. We discuss the completeness of
WASP survey techniques by comparing to the HATnet project
