Measuring and characterizing the line profile of HARPS with a laser frequency comb
Fei Zhao, G. Lo Curto, L. Pasquini +13
Aims. We study the 2D spectral line profile of HARPS (High Accuracy Radial Velocity Planet Searcher), measuring its variation with position across the detector and with changing li…
Performance Verification of the EXtreme PREcision Spectrograph
Ryan T. Blackman, Debra A. Fischer, Colby A. Jurgenson +25
The EXtreme PREcision Spectrograph (EXPRES) is a new Doppler spectrograph designed to reach a radial velocity measurement precision sufficient to detect Earth-like exoplanets orbit…
A crucial test for astronomical spectrograph calibration with frequency combs
Rafael A. Probst, Dinko Milaković, Borja Toledo-Padrón +23
Laser frequency combs (LFCs) are well on their way to becoming the next-generation calibration sources for precision astronomical spectroscopy. This development is considered key i…
LARS - An Absolute Reference Spectrograph for solar observations, Upgrade from a prototype to a turn-key system
J. Loehner-Boettcher, W. Schmidt, H. -P. Doerr +4
LARS is an Absolute Reference Spectrograph designed for ultra-precise solar observations. The high-resolution echelle spectrograph of the Vacuum Tower Telescope is supported by a s…
Comb-calibrated solar spectroscopy through a multiplexed single-mode fiber channel
R A Probst, L Wang, H-P Doerr +7
We investigate a new scheme for astronomical spectrograph calibration using the laser frequency comb at the Solar Vacuum Tower Telescope on Tenerife. Our concept is based upon a si…
