Attaining m s⁻¹ level intrinsic Doppler precision with RHEA, a low-cost single-mode spectrograph
We present RHEA, a compact and inexpensive single-mode spectrograph which is built to exploit the capabilities of modest-sized telescopes in an economic way. The instrument is fed by up to seven optical waveguides with the aim of achieving an efficient and modal-noise-free unit, suitable for attaining extreme Doppler precision. The cross-dispersed layout features a wavelength coverage from 430-650 nm, with spectral resolution of R∼75,000. When coupled to small telescopes using fast tip/tilt...[Show more]
