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 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.

But until recently the exoplanet community had access to large samples of just radii for small planets. TESS is enabling us to finally also measure the masses of an ensemble of small planets. Complementarily we propose to use CHEOPS to measure precise radii for seven small TESS planets in order to constrain their interior composition and explore the period-radius valley. The proposed observations will also serve to constrain the orbital eccentricity of these planets provide an anchor point at visible wavelengths for infrared transmission spectroscopy observations. For one planet it may also significantly refine the ephemeris since it is not yet known whether TESS will re-observe it.    [truncated! Please see actual data for full text]

Only five such systems are known so far. 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!

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.

Their physical nature also constitutes a mystery with their bulk compositions still allowing them to be either rocky water worlds or gas-giants (e.g. Rogers and Seager 2010) possibly in connection to photoevaporation of their initial atmospheres as they migrate towards the stars (e.g. Owens and Wu 2013) or due to core-powered mass-loss (e.g. Rogers et al. 2021). We request high-quality CHEOPS observations to dynamically determine the planet masses and radii via transit timing variation (TTV) measurements to identify prime targets for atmospheric follow-up characterisation with JWST to put constraints on their formation histories and to search for further non-transiting and still undetected long-period planets via the TTVs. The five planets are the unique best targets for this science case in CHEOPS AO-03 to our knowledge (observable both by CHEOPS and ASTEP not observed by CHEOPS yet and not in the CHEOPS Reserved Target List).

This system is unique for the availability of both precise Kepler/K2 eclipse light curves from and radial velocities of all three components. In Alonso et al. (2015) we derived the components’ physical and orbital parameters with high precision indicating significantly inflated stellar sizes albeit the size of the system’s largest component is in tension with established models of young stars. With  CHEOPS we intend to reobserve several eclipses towards an actualized determination of the systems parameters. Particularly this should lead to a much improved determination of the system’s osculating orbital parameters due to a coverage that would span 9 years versus the 79 days from K2. Such improved osculating parameters should permit a derivation of the internal mass-distribution of the system’s inner binary through determination of the apsidal constant k_2. Reducing uncertainties on the orbital parameters found by Alonso et al. will also significantly improve the precision of the system’s physical parameters and permit a calibration of pre-main sequence star parameters and of the evolution of their stellar interiors. CHEOPS is uniquely suited to perform the observations of the long complex eclipses with a required (and expected) precision that should rival the original Kepler/K2 data.    [truncated!

It hosts at least 4 transiting planet candidates all about the size of Neptune orbiting within 16 day orbital periods. The planets orbit near mean motion resonances so transit timing variations should reveal their masses.
