(ALPHACEN)   Abstract:  Alpha Centauri is the third brightest star in the night sky and the closest stellar system to us. It is composed of two stars similar to the Sun Alpha Cen A and B and a more distant but gravitationally bound red dwarf Proxima (the actual closest star to the Sun). In 2012 Dumusque et al. (Nature 491 207) announced from RV measurements a planet orbiting Alpha Cen B but its existence is still under debate. In 2015 Demory et al. (MNRAS 450 2043) found in highly-saturated Hubble Space Telescope observations of Alpha Cen B a single transit-like event ~95 ppm deep and ~3.6 h long. A likely explanation is an Earth-sized planet with an orbital period shorter than 20 days (the median of the likely orbits is 12.4 d).   With this program we aim to observe Alpha Cen with CHEOPS in order to try to recover the transit seen by Demory et al. (2015). More generally CHEOPS observations will allow us to place strong constraints on the presence of close-in transiting planets around Alpha Cen which is a very valuable objective on its own and complementary to the current efforts for direct imaging of farther planets around Alpha Cen (Kasper et al. 2019 The Messenger 178 5).

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.

These transit observations are crucial for precisely determining the orbits of these planets for future atmospheric characterisation. The improved radii and orbital parameters of the CHEOPS will in turn allow of better mass determination from an extensive RV campaign improving the bulk density and interior structure models and thus helping test the super-puff nature of planet c and improve the atmospheric characterisation from future atmospheric observations.

This means that signals detected at low signal-to-noise by TESS can be confirmed with CHEOPS. We will observe such low SNR candidates from TESS with a three-fold objective:   1) we will follow-up tentative signals in multi-planet systems as these are less likely to be false positives than systems with a single planet   2) we will prioritize the confirmation of candidates that can be confirmed by ongoing and future radial-velocity campaigns   3) we will collect sufficient transits to measure radii with a precision of at least 6%. Such precision coupled with a 10% precision on the planetary mass is necessary for a detailed analysis of both the internal structure of the exoplanet and the formation/evolution process of the system.

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!

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.

However the accurate characterisation of parameters like the radius of the planet is limited by the enhanced activity of the host star. The impact of features like unocculted and occulted active regions is a growing challenge in the era of high-precision photometry and transmission spectroscopy and better characterisation of these features is now more vital than ever for the correct interpretation of atmospheres on exoplanets. Here we propose to precisely characterise the HIP 67522 system a 17 Myr Solar-like star exhibiting significant stellar activity and one of the youngest planet-hosting stars discovered to date. The HIP 67522 system consists of one confirmed transiting hot Jupiter (planet b) and an unconfirmed outer planet candidate (planet c). To characterise this key young system we aim to: i) obtain an accurate and precise radius measurement for the known transiting planet (planet b) by quantifying the effect of stellar activity on its transit depth and ii) confirm the candidate exoplanet (planet c) by following up the most likely period aliases of its two known transits. While accurately measuring the radius of planet b is vital for testing different planet formation and evolution models for hot Jupiters confirming planet c will make this the youngest multi-planet transiting system ever discovered making this a very compelling system to be observed by CHEOPS.

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.

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.

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. The two methods have a great synergy as TTVs allow for in-depth characterization of  [truncated! Please see actual data for full text]

Heavier components sink and form metallic cores whilst pebbles from beyond snow lines deliver volatiles influencing atmospheres or water on Earth-like planets. Understanding the composition of planetary ingredients is vital. Planetary refractory elemental abundances mirror stellar values  the Earth is a devolatised piece of the Sun. If this is universal we would expect a diversity in internal structures and atmospheres of planets orbiting metal-diverse stars. This is currently not well investigated however in recent years tantalising evidence has emerged for metallicity-driven trends in the physical characteristics of super-Earth and sub-Neptune exoplanets. These first pieces of evidence might be pointing towards chemically-diverse formation scenarios impacting the internal structures of planets however this is currently unclear as there are very few well-characterised small planets around metal-poor stars. Therefore this program will refine the radii of a handful of key planets around Galactic thick-disk metal-poor host stars to an unprecedented level in order to solve the current mysteries that we are just starting to unravel.
