DESCRIPTION:"High-resolution\, stabilised\, echelle spectrographs play a k
 ey role in exoplanet science\, from the discovery of the first exoplanet a
 round a main-sequence star\, to the study of planetary atmospheres\, the c
 haracterisation of planetary systems and now\, the forefront of the search
  for Earth-like planets.\nFrom an optics perspective\, high-resolution ech
 elle spectrographs are extremely constrained systems\, with each top-level
  parameter impacting the design of the rest of the optical system.\nThis t
 alk will present an overview on the design of echelle spectrographs and so
 me of the factors that impact their stability.\nWe will discuss the applic
 ation of these concepts to HARVY: A Highly-repeatable Autonomous extreme-p
 recision Radial Velocity facilitY concept.\nThe HARVY concept consists of 
 four highly efficient (goal: 30% throughput)\, compact (instrument footpri
 nt: ~0.6mX0.5mX0.15m)\, extreme precision (req: 20cm/s\, goal: 5cm/s instr
 ument stability) radial-velocity\, echelle-spectrographs each efficiently 
 coupled to their own off-the-shelf 1.5m telescope\; with the aim to increa
 se the accessibility of radial velocity facilities\, easing the bottle-nec
 k on exoplanet transit follow-up and enabling further large-scale intensiv
 e search for low-mass\, long-period\, ‘Earth-like’ planets around main
 -sequence stars."
