Second-Generation Fabry-Pérot Unit for CARMENES
Hanna Lina Pleteit, Michael Debus, Sebastian Schäfer +1
CARMENES consists of two high-resolution spectrographs located at the Calar Alto 3.5m telescope, covering the wavelength range from 520nm to 1710 nm. The original Fabry-Perot (FP)…
MOSES -- The MONET Star and Exoplanet Spectrograph
S. Schäfer, L. Schmidt, H. Anwand-Heerwart +2
We introduce MOSES, the new High-Resolution Echelle Spectrograph designated for the 1.2m MONET telescope at McDonald Observatory, Texas, USA. The science drivers are radial velocit…
Large-scale time-series spectroscopy for stellar ages
David Gruner, Sydney A. Barnes, Ansgar Reiners +16
To date, Galactic Astronomy has largely concerned itself with astrophysical processes, and with the locations, space motions and compositions of objects. Consider, for example, the…
Revisiting the atmosphere of HAT-P-70b with CARMENES high-resolution transmission spectroscopy
Tianjun Gan, Jaume Orell-Miquel, Fei Yan +19
Owing to hot and inflated envelopes that facilitate atmospheric studies, ultra-hot Jupiters (UHJs) have attracted much attention. Significant progress has been achieved, from enlar…
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…
Precise and efficient modeling of stellar-activity-affected solar spectra using SOAP-GPU
Yinan Zhao, Xavier Dumusque, Michael Cretignier +4
One of the main obstacles in exoplanet detection when using the radial velocity (RV) technique is the presence of stellar activity signal induced by magnetic regions. In this conte…
