  • Abstract: HD 114082 is a bright, relatively nearby, very young F-type star in the Scorpius-Centaurus (Sco-Cen) OB Association. It bears a nearly edge-on debris disk (Wahhaj et al. 2016) and HD 114082 b, a massive planet that defies current theoretical planet formation models (Zakhozhay et al. 2022, Engler et al. 2023). The planet produced a single-transit event during the TESS observations and its orbital period was later determined using radial velocities. A second transit event detected in March by the NGTS survey provided a set of three plausible orbital periods, one of them similar but still different from that derived from the radial velocity curve. The other two are quite unlike. This is not entirely surprising, as constraining the orbital period of young planets solely from radial velocity measurements is very challenging and prone to underestimate uncertainties due to limitations in the stellar activity modelling. The most reliable way of confirming the orbital elements is detecting and analysing new transit events, preferably from space. We propose to use 86.1 CHEOPS orbits to observe HD 114082 during three candidate transit events, in accordance with the estimated orbital periods, to confirm and refine the planet ephemeris and improve its characterisation.

Mission Description CHEOPS (Benz et al., https://doi.org/10.1007/s10686-020-09679-4) is a European Space Agency (ESA) mission in partnership with Switzerland with important contributions to the payload and the ground segment from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden and the United Kingdom.

The satellite has a single payload comprising an ultra-high precision photometer covering the 330 - 1100 nm wavelength range in a single photometric band. Observations are made as part of the Guaranteed Time Observing Programme that is formulated by the CHEOPS Science Team, and the Guest Observers Programme through which the Community at large can apply for CHEOPS time.
