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.

In the near future the PLATO mission will survey with high precision the photometric variations of bright stars inxa0specific areas of the sky. The combination of those observations with the most precise spectrographs will certainly be of upmost interest to alleviate stellar activity effects and provide mass measurements below the meter per second level needed to reach PLATO’s science goals. CHEOPS represents a unique opportunity to take a step ahead in prevision of PLATO and valuably support extensive RV surveys. We propose a long-term absolute photometry campaign in parallel to an already secured intense RV monitoring on HD151288 a moderately active star with yet-unclear activity patterns. In the fashion of a filler program with very limited constraints those observations could shed light on the complex RV stellar activity signals and they would serve as a benchmark for CHEOPS long-term stability and ability to conduct precise absolute photometry.

Measuring the tidal deformation of the planet allows us to estimate the second-degree fluid Love number and gain insight into the planets 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.).

Our goal is to increase the sample size by confirming and characterizing five TESS candidates with such an architecture and improving their orbital/physical parameters including ephemeris radii and (when feasible) planetary masses through TTVs. As demonstrated by our work on WASP-47 RVs and TTVs are very synergistic at decoding these complex systems. A dedicated RV follow-up will be coordinated.    [truncated!

In particular several studies have demonstrated that different thermal structures and wind patterns over the morning and evening terminator can produce an inhomogeneous cloud coverage over the atmosphere. However a common assumption made while performing transmission spectroscopy of exoplanets is of a homogeneous atmosphere. Considering such an inhomogeneous atmosphere as a homogeneous one can lead to biases in retrieved atmospheric properties. Inhomogeneities in the atmosphere also leave an impact on broadband photometry. In this program we aim to detect this effect directly on the transit lightcurve of three planets. The magnitude of this effect could be as large as 1000 ppm for suitable targets which CHEOPS should be able to detect comfortably. While inhomogeneity can be in chemical structure or aerosol properties we mainly aim to put constraints on asymmetric cloud coverage with CHEOPS observations. We have identified WASP-54 b HAT-P-30 b and WASP-131 b as being the best candidates for detection due to their atmospheric transmission signal transit duration and temperature. Our observations would pave a way for future observations with spectroscopic capabilities to constrain the inhomogeneous atmospheres of these planets.    [truncated!

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.
