These planets either contain more than around one percent of gas (in mass) or no gas at all (see Owen and Wu 2017). This dichotomy when expressed in term of mass-radius relation implies the existence of a region in the mass-radius diagram of hot planets where dry planets cannot exist. We propose to observe planets that could lie in this region with CHEOPS. Combining a precise radius and mass will allow us to identify planets in this forbidden region hence showing that they have to contain volatiles most likely water. Our data combined with future JWST observations will also constrain the efficiency of evaporation.    [truncated! Please see actual data for full text]

Identifying non-TOI candidates with CHEOPS   Abstract:  We propose to perform CHEOPS transit photometry of non-TOIs i.e. small planet candidates detected in TESS light curves with a relatively low signal-to-noise ratio (S/N < 7). More specifically the program aims at 1) excluding false alarms and increasing the significance of the transit detection  2) identifying additional transiting planet candidates (aka ChOIs) in bright TESS systems already known to host a TOI  3) improving the transit ephemeris and parameters.

Recent observations of a bright and nearby (12 pc) M-dwarf by TESS have revealed the presence of an Earth-sized exoplanet with a relatively low incident flux (no more than twice Earth's insolation). However the unfortunate coincidence of the planetary orbital period with gaps in the TESS photometry means that there is a factor-of-two uncertainty in the orbital period. We propose CHEOPS observations to resolve this period ambiguity and to more precisely characterise the physical parameters of the planet. Transit observations from CHEOPS will contribute significantly to our understanding of this system and will form a key basis for current and future characterisation efforts of this remarkable planet.

The minute details of their architectures encode the history of their formation: the order of the capture of the planets in the chain (Delisle 2017) the local shape of the proto-planetary disc and its dispersal (e.g.  Nesvorny et al 2022) and the long-term evolution of the system through tidal dissipation (e.g. Papaloizou et al 2018). The high multiplicity of these systems also makes them especially valuable to constrain our models of the formation of planetary systems (See Emsenhuber et al 2022 and other papers of the NGPPS series) since all the planets have to form in the same environment and the relative fragility of the configuration ensures that no violent evolution (e.g. close encounters/impacts) occurred after the dissipation of the proto-planetary disc (Leleu et al 2021). In addition the transit timing variations induced by the compactness of the systems allow for precise mass determination down to a few per cent in the case of Trappist-1 (Agol et al 2021). This allows an in-depth characterization of moderately insolated rocky planets and mini-Neptune with a precision which is rarely reachable through radial velocities enabling studies of their interiors and atmospheres. The brightness of the current targets of the program (Gaia band mag 11 for TOI178 12 for K2-138 8.4 for TOI1835) allows to combine RVs and photometric measurements.

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.

In spite of that their interior composition and therefore their origin has to date not been constrained observationally. The reason is the degeneracy in possible compositions that can explain their observed properties. Two end member compositions are theoretically suggested: dry rocky cores + about 1% of H/He or ocean planets containing about 50% water in mass. The former is suggested by evolutionary evaporation models the later by formation models. These compositions correspond to fundamentally different in situ formation versus orbital migration pathways. If observationally it should turn out that close-in sub-Neptunian planets are indeed water worlds this could be seen as one of the largest successes of planet formation theory. The opposite case would mean that one or several elements of our current understanding of the origin of planets is fundamentally flawed. It is therefore of paramount importance to answer the fundamental question “What are sub-Neptunes made of?”. With this program we propose a three-faceted approach to answer this question: 1) is there a grouping in density? 2) Preparing for the JWST opportunity. 3) Is the ice mass fraction correlated with the stellar composition? We propose to use CHEOPS for the precise radius determination of a carefully chosen sample of TESS planet candidate whose radii make them susceptible to be either ocean worlds or rocky cores with H/He envelopes.
