UKIRT has assisted in the discovery of SPECULOOS-3 b—an earth-sized exoplanet in a 17 hour orbit around an M6.5-type dwarf star 16.8 parsecs away. A K-band transit light curve was obtained from UKIRT using the UKIRT Wide Field Camera (WFCAM) on two epochs. The exoplanet is suitable for spectroscopic studies from JWST.

Pictured above are the phase-folded transit light curves of SPECULOOS-3 b. The purple light curve at the bottom shows the K-band photometry obtained using UKIRT and WFCAM.
