VizieR Online Data Catalog: Radial velocity and light curves of WASP-190 (Temple+, 2019)

We observed WASP-190 using the WASP-South telescope (Hellier et al. 2011EPJWC..1101004H) at the South African Astronomical Observatory (SAAO) from 2006 to 2011. After the detection of a planet-like transit dip in the WASP light curve we confirmed the transit with a follow-up light curve obtained using the TRAPPIST-South telescope (Jehin et al. 2011Msngr.145....2J), and proceeded to obtain reconnaissance spectroscopy with the Euler/CORALIE spectrograph (Queloz et al. 2001Msngr.105....1Q). These were sufficient to rule out a stellar-mass binary, but, with relatively large errors, were consistent with no motion at the level of 250 m/s, and were inconclusive in finding whether or not the transiting body was a planet. We thus attempted tomography of a transit, obtaining a series of 28 spectra through transit on the night of 2017 October 13 using the European Southern Observatory (ESO) 3.6 m/HARPS spectrograph (Pepe et al. 2002Msngr.110....9P), accompanied by simultaneous photometry using the SPECULOOS-Europa telescope (Burdanov et al. 2018haex.bookE.130B; Delrez et al. 2018SPIE10700E..1ID; Gillon 2018NatAs...2..344G). After tomographic detection of a planet-like signal, we obtained five further orbital RVs with HARPS to constrain the planetary mass.
