Studying giant planets around evolved stars provides useful information on the impact of stellar evolution on planets their atmospheres and the architecture of planetary systems in general. These planets can also contribute to understanding the mechanism for late-stage planet inflation. It is thus necessary to have a good statistical sample of well-characterized giant planets around evolved stars. This program performs follow-up of TESS planet candidates around evolved stars to refine the radii of detected planets and also detect additional planets in order to populate this parameter space and allow better statistical study.

However the vast majority of such planets have short (P<20d) orbital periods. This is because long-period transiting planets do not produce consecutive transits in photometric survey data. However these planets are some of the most interesting as unlike their interior companions they are less affected by the gravitational and electromagnetic effects of their host stars. This programme will use CHEOPS to efficiently detect characterisable small transiting planets on long orbital periods. We will do this by leveraging as much external information as possible to constrain orbital periods - from nonconsecutive transits (i.e. mono- duo- or trio-transit candidates) in photometric survey data such as K2 or TESS and from radial velocities where available. Such techniques have been successful in the CHEOPS nominal mission with for example the photometrically-constrained TOI-2076 c  and  d (Osborn et al 2022) or the monotransit+RV case of TOI-561 d  and  e (Lacedelli et al 2021  and  2022). These planets once found by CHEOPS may also form interesting science targets for other parts of the GTO extended mission science case such as studying the architectural diversity of exoplanetary systems and even searches for exomoon  and  rings.

For Rings targets are giant planets beyond the snow line so best candidates are also giant planets with long periods.

This correlation results from the following two processes: On one hand the temporal evolution of the gas content of the protoplanetary disk causes migration of the planets and therefore determines the orbital architecture of the system. On the other hand the composition of the planets depends on the structure and composition of the disk of solids itself related to the gas content of the disk and the solid-to-gas ratio in the disk. This latter quantity is finally correlated with the stellar metallicity. The goal of ArchiCHESS is to observe multi-planetary systems to constrain their architecture (using architecture coefficients of Mishra et al. 2023) and relate this to the water fractions of the planets as well as to the metallicity of the central star.

Measuring the tidal deformation of the planet allows us to estimate the second-degree fluid Love number and gain insight into the planet's internal structure. Moreover measuring the tidal decay timescale allows us to estimate the stellar tidal quality factor which is key to constraining stellar physics. Therefore studying tidal effects in ultra-short orbital period planets gives us a wealth of information on planet-to-star tidal interactions that shape planetary systems. We also propose to estimate the tidal decay of a few hot-Jupiters for which we expect a measurable orbital period decrease within the next 3 years. The longer baseline allowed by the CHEOPS extension will be crucial for our ability to measure the tidal decay of some systems. During the CHEOPS nominal mission we achieved a breakthrough on the direct detection of the tidal deformation of exoplanets. Building on these results we also propose to better constrain the tidal deformation of WASP-103b and WASP-12b directly from the transit deformation signature (similar to  Barros et al. 2022) and also from the signature in the phase curve (similar to Akinsanmi et al. in prep.).

One specific type of such candidates are Duotransits - candidates with two transits separated by a large gap (as is the case for around 400 TESS candidates observing in the primary and extended missions). Here Cheops is perfectly placed to recover the periods of such long period planets by observing potential period aliases. In this program we propose to use this method to recover the periods of super-Earths  and  Neptunes around bright stars with Cheops.    [truncated! Please see actual data for full text]

However confirming/investigating grazing transiting exoplanets is also important. In a grazing transit the second and third contact points are missing the transit profile is V-shaped similar to that of an eclipsing binary. Consequently the light-curve solution is degenerate. Fortunately there is a solution: we need very high-quality multicolour photometric observations. Following this possibility we propose to utilise the colour difference between TESS and CHEOPS in order to refine the parameters and to confirm the grazing nature of selected transiting exoplanets namely TOI-3540 b and TOI-2193 b.
