Validation of the ESPRESSO Wavelength Calibration Using Iodine Absorption Cell Spectra
Tobias M. Schmidt, Ansgar Reiners, Michael T. Murphy +3
High quality wavelength calibration is crucial for science cases like radial-velocity studies of exoplanets, the search for a possible variation of fundamental constants, and the r…
HIRES, the high-resolution spectrograph for the ELT
Alessandro Marconi, Manuel Abreu, Vardan Adibekyan +99
HIRES will be the high-resolution spectrograph of the European Extremely Large Telescope at optical and near-infrared wavelengths. It consists of three fibre-fed spectrographs prov…
A giant exoplanet orbiting a very low-mass star challenges planet formation models
J. C. Morales, A. J. Mustill, I. Ribas +179
Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…
A systematic approach to determining the properties of an iodine absorption cell for high-precision radial velocity measurements
V. Perdelwitz, P. Huke
Absorption cells filled with diatomic iodine are frequently employed as wavelength reference for high-precision stellar radial velocity determination due their long-term stability…
The CARMENES search for exoplanets around M dwarfs - HD 147379b: A nearby Neptune in the temperate zone of an early-M dwarf
A. Reiners, I. Ribas, M. Zechmeister +169
We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around M dwarfs. HD 147379…
Radial velocity observations of the 2015 Mar 20 eclipse - A benchmark Rossiter-McLaughlin curve with zero free parameters
Ansgar Reiners, Ulrike Lemke, Florian Bauer +2
On March 20, 2015, we obtained 159 spectra of the Sun as a star with the solar telescope and the FTS at the Institut für Astrophysik Göttingen, 76 spectra were taken during partial…
