A Terra Hunting Experiment at the INT Rationale To detect smaller mass planets (down to 1Mе) using the radial velocity technique, we need to be able to retrieve a signal in the limit of stellar variability noise. ... Such an observing program is not feasible with a non-dedicated telescope. To address this, we are proposing a "Terra Hunting Experiment" to be performed using a close-copy of the HARPS spectrograph installed on the 2.5m Isaac Newton Telescope (INT) in La Palma. ...
