Query: WASP-80b: a gas giant transiting a cool dwarf   We report the discovery of a planet transiting the star WASP-80 (1SWASP
J201240.26-020838.2; 2MASS J20124017-0208391; TYC 5165-481-1; BPM 80815;
V=11.9, K=8.4). Our analysis shows this is a 0.55 +/- 0.04 Mjup, 0.95 +/- 0.03
Rjup gas giant on a circular 3.07 day orbit around a star with a spectral type
between K7V and M0V. This system produces one of the largest transit depths so
far reported, making it a worthwhile target for transmission spectroscopy. We
find a large discrepancy between the v sin i inferred from stellar line
broadening and the observed amplitude of the Rossiter-McLaughlin effect. This
can be understood either by an orbital plane nearly perpendicular to the
stellar spin or by an additional, unaccounted for source of broadening.
