  • Title of programme: What is the nature of the young planets in the V1298 Tau System?
  • Abstract: The newborn planetary system comprising of four gas giants transiting the bright 23 Myr old star V1298 Tau presents an exciting opportunity to probe the properties of planetary systems immediately post formation, and to do so within one system. We propose to observe the transits of the hottest inner three Neptunes and sub-Neptunes planets in the system, V1298 Tau b,c, and d. We will measure their mass dynamically through transit timing variations (TTVs), we will improve the precision on their radii, and we will estimate the eccentricity of planet b, the one with the longest period of the inner three planets. In turns, these measurements will inform us about the nature of this planet: we will unveil whether these planets are Neptune-mass objects, or whether they are at lower density.This is important, because such young system are thoughts to be the progenitors to the population of Super-Earths and Mini-Neptunes that have been detected extensively by exoplanet surveys. Ultimately, the planets of the V1298 Tau system could evolve towards planets that straddle the radius valley.

Mission Description CHEOPS (Benz et al., https://doi.org/10.1007/s10686-020-09679-4) is a European Space Agency (ESA) mission in partnership with Switzerland with important contributions to the payload and the ground segment from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden and the United Kingdom.

The satellite has a single payload comprising an ultra-high precision photometer covering the 330 - 1100 nm wavelength range in a single photometric band. Observations are made as part of the Guaranteed Time Observing Programme that is formulated by the CHEOPS Science Team, and the Guest Observers Programme through which the Community at large can apply for CHEOPS time.
