Being interested to micro-variability on time scales from few seconds to a hours even one CHEOPS orbit can get useful data.

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]

The geometric and Bond albedo measurements constitute the majority of the subject's observational constraints. Reflected light phase curves hold the key to gaining a better understanding of the fundamental scattering properties: single scattering albedo and asymmetry as well as determining the degree of inhomogeneity in the spatial distribution of clouds hazes and aerosols. However due to observational biases the vast majority of existing datasets that show a clear phase curve signal in the visible are aimed at hot gas giants. As a result they are plagued by the degeneracy between reflected and thermal light. Only Kepler-7 b was cool enough and Kepler sensitive enough to deliver a high precision phase curve that is dominated by reflected light. Kepler-7 b is thus the only exoplanet for which we have direct measurements of  cloud distribution inhomogeneity and fundamental scattering properties.  With this program we will leverage CHEOPS’ photometric precision bandpass and pointing flexibility to perform repeated phase curves observations of a few key targets. These canonical datasets will provide precise reflected light phase curves and will offer long-awaited counterparts to Kepler-7 b. We will investigate atmospheric inhomogeneity and measure fundamental scattering properties. We will begin to explore th [truncated! Please see actual data for full text]

However distinguishing between the different kinds of condensates is hard as degeneracies emerge when analyzing photometric and spectral data. High precision optical phase curves can help disentangle these degeneracies as the peak offset of the optical phase curve is sensitive to the cloud's composition. We aim to observe two phase curves of the Hot Jupiter HIP 65A b and three phase curves of the Hot Jupiter WASP-77A b. HIP 65A b has anxa0equilibrium temperature of 1410 K an orbital period of 0.98 days and a poorly constrained radius between 2.64 and 1.54 RJ.xa0 WASP-77A b has an equilibrium temperature of 1715 K an orbital period of 1.35 days and a radius of 1.230 RJ.xa0 These observations will allow us to refine the constraints on the planetary radius (in particular for HIP 65A b) to constrain the geometric albedo and potentially to discriminate between different forming clouds. They will also be useful for the preparation and interpretation of future observations by JWST and ARIEL as well as characterizations by high spectral resolution observations by SPIRou or CRIRES.

Observing young planetary systems allow us to gain insights into the physical processes that shape the mature planetary population. TIC 434398831 is a pre-main-seqeunce Sun-like star (G7V G = 11.7893) hosting two transiting mini-Neptunes. Gaia kinematics place TIC 434398831 in the 48-Myr Taurus-Orion II moving group. We identified two planetary candidates TIC 434398831.01 (Rp = 3.65 Rearth P = 3.61 days) and TIC 434398831.02 (Rp = 5.41 Rearth P = 6.12 days) through an independent search for young planets located in known moving groups from the TESS's Full Frame Images (FFIs) light curves. We propose to use 4 visits of CHEOPS to observe two transits of both TIC 434398831.01 and TIC 434398831.02 which is necessary for the confirmation of this exemplar system as high-precision space-based photometry is needed to overcome the photometric modulations of the young star. Our CHEOPS observations will have the capability to anchor the optical transit depths of the two young planets which will enable us to distinguish between different cloud and haze scenarios in future atmospheric observations.
