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.

Being interested to micro-variability on time scales from few seconds to a hours even one CHEOPS orbit can get useful data. The measured parameters - mean variance pooled variaance flares/microflares occurence rate dips occurence rate power spectrum -  will be related  to stellar properties (Teff H-alpha Ca II H and K X-ray and UV fluxes).  Selected targets spans subclasess of late type stars with different level of activity. They have been selected among those  with already know stellar properties (typicall surveyed for exoplanet detection)  and include all  dM / late K and TTau  with  planets.    [truncated!

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.

Abstract:  During the past thirty years astronomers have discovered many extrasolar planets (e.g. Batalha et al. (2013)) which has sparked an excitement in the community whether these exoplanets may host a detectable and/or a habitable satellite so called extrasolar moon or exomoon. The technological and theoretical methods now allow the detection of sub-Earth-sized extrasolar planets and the first detection of an extrasolar moon appears feasible (Heller et al. 2014) but so far there is not a single case where the existence of an exomoon could have been demonstrated. Detecting the first exomoon would be a major discovery because moons can be new places for habitability Awiphan and Kerins 2013  Heller and Barnes 2013a  Heller 2012 can play a significant role in the evolution of the host planets and can play a key role in stabilising rotation axis (as Moon does for Earth Laskar et al. (1993)). Even though the mechanisms of moon formation are not fully understood moons seem to be an outcome of planet formation and a presence of exomoons would provide invaluable information on the planet’s interior and formation process (Crida and Charnoz 2012). To answer the question ”Where are the exomoons?” we would like to continue the search for them in the extended phase of the CHEOPS mission.    [truncated! Please see actual data for full text]

High-precision radial velocity observations of AU Mic are hampered by the activity of the star as recently shown by Zicher et al. 2022 (MNRAS 512 3060) who measured the masses of planet b and c with a precision of “only” 43 % and 30 % using more than 100 HARPS measurements evenly spread across one year. Conversely CHEOPS have proven to be very effective in measuring planet masses of near-resonant transiting systems such as TOI-1130 b and c for which a precision of ?9 % has been achieved exploiting the TTV method. Our program requires transit observations of planet b and c to be carried out in July August. • studying the evolution time-scale of active regions across the transit cord using AU Mic b as a “scanner”. Unbiased measurements of Rp/R? can be determined only by modeling the transit light curves along with the map of the occulted (and unocculted see below) spots. This requires CHEOPS multiple observations of the transits of AU Mic b at the 4 possible star-planet configurations. By observing spot-crossing events of transits occurring at the same stellar longitudes as in 2020 and 2021’s CHEOPS observations we will also assess whether the distribution of spots has evolved or not.

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.
