K2-111 Archives

Combined fit results for K2-79 b. Transit fit to the light curve data from K2 long cadence (first row left), TESS long cadence (first row centre), and CHEOPS (first row right). The cadence (29.4 min for K2 long cadence, 120 s for TESS long cadence, and 60 s for CHEOPS) fluxes are plotted in grey, the fluxes binned every 30 min are over-plotted in black, and the fitted transit is shown by the red solid line. The RV fit to the HARPS-N & HIRES RVs is shown in the second row for K2-79 b. Coloured circular points show the phase folded RVs, grey points show these same values in subsequent phases, and the black line shows the best fit Keplerian model. The third row shows the RVs over the full ∼ 9 yr baseline, illustrating the absence of any significant long term trend. -- astro-ph.EP

Accurate mass and radius measurements of small transiting exoplanets are essential for probing their compositions, formation histories, and potential habitability.
