Here propose to observe the transits of two planets in the K2-266 system K2-266d and K2-266e in order to more robustly constrain the previously reported TTVs. These data will allow us to obtain much more precise mass and orbital parameters of this unique system. TESS has observed the system already adding to the time baseline relative to the original K2 observations but the TESS data are not accurate enough to distinguish between competing models. However as discussed in the scientific justification of this proposal the CHEOPS data proposed here is able to distinguish between different models with small differences in the system parameters. The ability to precisely distinguish between competing models means the CHEOPS data will provide a high precision measurement and bring a large impact into the study of this astronomically important planet system. Furthermore as members of the Twinkle Space Mission’s exoplanet TTV Working Group we aim to observe this system with Twinkle in the future. While the data proposed for here is valuable in its own right combining data from both these small low-Earth orbit satellites over a long baseline will yield better results than using either one alone.

Planet formation is a complex process that starts with the condensation of matter in a disc of molecular gas and dust. Planetesimals grow into planets accrete material lose volatiles chemically evolve and outgas contract as they cool down and finally are destroyed or survive when the star dies ejecting back material into the interstellar medium and possibly starting again a new cycle. Most of the evidence that we have on these processes comes from the study of our Solar System and astrophysical observations of neighboring stars. The detection and characterization of extrasolar planets revealed a diversity of planetary systems beyond the Solar System but these discoveries challenged existing planet formation theories. Precisely characterized bulk properties of exoplanets help place constraints on the varying formation conditions and evolution processes in order to understand the origin of exoplanets. In this program we propose the characterization of long-period (P > 15 days) low-mass gas-rich planets (defined as planets with radii between 2 and 4 Earth radii) by refining their planetary radii.

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.

This program will perform a deep search for variability in the dayside brightness of several hot Jupiters. A detection of clear variability and the measurement of its timescale would open the door to a suite of follow-up studies involving the dynamical behaviour of exoplanet atmospheres.    [truncated!

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]

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!

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]
