In search of Exo-earths: Development of next generation spectrographs for discovering planets around other stars
Search for earth-like exoplanets in habitable zone (exo-earths) has been the holy grail in exoplanet astronomy research. The extreme precision radial velocity (EPRV) community have made incredible progress in building ultra-stable spectrographs for bringing down the measurable radial velocity (rv) precision to sub-m/sec. However, to detect earth-like planets around sun-like stars in earth-like orbits, we need to be able to measure radial velocities at a few cm/sec level.
For comparison, our Earth has ~9 cm/sec rv effect on our Sun.
