Add  Attaining m s⁻¹ level intrinsic Doppler precision with RHEA, a low-cost single-mode spectrograph
Authors: Feger, Tobias | Ireland, Michael J | Schwab, Christian | Bento, Joao | Bacigalupo, Carlos | Coutts, David W
Date: 2016
Subject Keyword: Instrumentation | Single-mode spectrograph | High-resolution | Radial velocity | Tube lens | Extrasolar planets | Asteroseismology
Language: eng
Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/1198978
Description: 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 optic ... More
