Towards Other Earths III: The Planet-Star connection03-07 July 2023, Porto, Portugal
Planetary systems result from the synergy between the stars and the planets they host. It can be convenient, at first, to consider them in isolation, but the links between them affect all aspects of exoplanetary sciences. Stars can be a hurdle to exoplanetary sciences. The precision and accuracy of our knowledge of stellar parameters is often a major driver for the precision and accuracy of the respective planetary parameters. Stellar activity and its impact on planet detection and characterisation is one of the significant challenges for the next decade. But stars can also be facilitators to exoplanetary sciences. The correlation between stellar metallicity and the frequency of giant planets is well established and the link between stellar and planetary composition is an active topic. In the next few years we also have a lot to learn from the dynamical interactions between stars and planets.
With this new edition of the Towards Other Earth conference series, we aim to gather again scientists from all around the world in Porto (Portugal), to discuss what has been learned from studying stars and planets together. In particular we wish to address:
- The impact of stellar activity on planet detection and characterisation but also on the evolution of planets and their atmospheres;
- The link between the stellar properties and the frequency, bulk and atmospheric composition of planets;
- The implications and different effects of the dynamical interactions between the stars and the planets that they host.
