Following the tradition of previous workshops organised in Penn State and Yale, this fourth opus will dig into the instrumental and data analysis challenges required to enable the detection of an Earth twin using Doppler velocimetry.

As we know, today's main limitations are the instrumental precision and stellar activity that perturb radial-velocity measurements. This edition of the workshop will therefore focus on:

  • lessons learned from past and next generation EPRV instruments,
  • hardware challenges,
  • modelling and diagnosing stellar noise,
  • mitigating stellar and instrumental noises.
