Due to the global confinement situation caused by the COVID-19 pandemic, we cannot guaranty that the Planets of red dwarf stars Colloquium can be held nor organized as planned in September 2020.
We are thus postponing the colloquium to next year, 2021.
We will announce the new dates and program later this year once the situation is stable again. If you have any question regarding the 2020 canceled edition, please contact ohp-colloque2020 AT lam.fr.
Scientific Rationale
Planets orbiting low-mass M-dwarf stars have been among the prime targets of exoplanet research for many years. The well-known reasons include an increased transit depth, radial velocity signal, and contrast with respect to planets orbiting hotter stars. With the upcoming telescopes and observatories such as JWST and the E-ELT, the characterisation of the atmospheres of rocky planets around low-mass stars is going to become feasible, and will open new avenues of research.
The Colloquium ``OHP-2020: planets of red dwarf stars’’ will review the last years of observational and theoretical advances in the research of planets around low-mass stars, including their detection and the characterisation of their interior structure and atmospheres. We hope to identify ways to advance the key questions and solve the most pressing issues regarding the study of these systems, exploring the synergies between current and new facilities, and theoretical advances.
The colloquium will focus on:
- detection of exoplanets around low-mass stars by radial-velocity, transit, and imaging surveys - characterisation of M-dwarf planets (e.g. atmospheres, interiors, obliquity, host multiplicity, etc.) - interior and atmospheric modelling (including habitability around red dwarfs) - stellar variability for the lowest-mass stars (granulation, rotation, activity cycles, etc.) - theories of formation and evolution - future instrumentation and observatories
The Observatoire de Haute Provence is located in Southern France, near the village of Saint Michel l’Observatoire. It is place of discovery of 51 Peg b --an achievement that earned Mayor & Queloz the Nobel prize in Physics in 2019-- and of the co-discovery of Gl876 b, the first planet detected around an M-dwarf star. The 193-cm telescope is now equipped with the SOPHIE spectrograph, which produces a steady contribution to exoplanet studies. Up to 80 participants are expected. Accommodation will be provided inside and close to the Observatory for the duration of the Colloquium. Students and post-docs are particularly encouraged to register and contribute their work. Limited financial support to cover travel and lodging expenses will be available for students/young researchers that submit abstract.
December 1st, 2019: first announcement and pre-registration.
March 5th, 2020: second annoucement and abstract submission.
May 1st, 2020: cancellation of the 2020 edition due to the COVID-19 pandemic.
