In this page, we show some examples of observations using REACH.

Resolving a high-dispersion spectrum of a close companion

HIP 18413 was a spectroscopic binary SB1 (Tokovinin+2019). Using REACH, we obtained high-dispersion spectra of the host star A and the companion D separately (gray regions indicate telluric lines). This observation was performed using non-coronagraphic mode (HRS-NC). Taken from the results of an engneering run in Oct 16th (2019).
