TESS re-observes the young multi-planet system TOI-451: refined ephemeris and activity evolution
Research Notes of the American Astronomical Society American Astronomical Society 5:3 (2021) 51
Abstract:
We present a new analysis of the light curve of the young planet-hosting star TOI 451 in the light of new observations from TESS Cycle 3. Our joint analysis of the transits of all three planets, using all available TESS data, results in an improved ephemeris for TOI 451 b and TOI 451 c, which will help to plan follow-up observations. The updated mid-transit times are BJD–2,457,000 = ${1410.9896}_{-0.0029}^{+0.0032}$ , ${1411.7982}_{-0.0020}^{+0.0022}$, and ${1416.63407}_{-0.00100}^{+0.00096}$ for TOI 451 b, c, and d, respectively, and the periods are ${1.8587028}_{-10e-06}^{+08e-06}$, ${9.192453}_{-3.3e-05}^{+4.1e-05}$ , and ${16.364932}_{-3.5e-05}^{+3.6e-05}$ days. We also model the out-of-transit light curve using a Gaussian Process with a quasi-periodic kernel, and infer a change in the properties of the active regions on the surface of TOI 451 between TESS Cycles 1 and 3.Planet Hunters TESS II: Findings from the first two years of TESS
