PySME v1.0: improved modelling of stellar spectra for survey-scale applications
Mingjie Jian, Nikolai Piskunov, Jeff Valenti +4
Stellar abundance analysis relies on flexible, high-performance spectral synthesis. To meet these needs, we present PySME v1.0, an updated Python implementation of Spectroscopy Mad…
Deep high-resolution L band spectroscopy in the Pictoris planetary system
Markus Janson, Jonas Wehrung-Montpezat, Ansgar Wehrhahn +4
The beta Pictoris system, with its two directly imaged planets beta Pic b and beta Pic c and its well characterised debris disk, is a prime target for detailed characterisation of…
Optimising spectroscopic observations of transiting exoplanets
Linn Boldt-Christmas, Fabio Lesjak, Ansgar Wehrhahn +4
When observing the atmospheres of transiting exoplanets using high-resolution spectroscopy, one aims to detect well-resolved spectral features with high signal-to-noise ratios (SNR…
CRIRES on sky at the ESO Very Large Telescope
R. J. Dorn, P. Bristow, J. V. Smoker +49
The CRyogenic InfraRed Echelle Spectrograph (CRIRES) Upgrade project CRIRES extended the capabilities of CRIRES. It transformed this VLT instrument into a cross-dispersed spe…
PySME -- Spectroscopy Made Easier
Ansgar Wehrhahn, Nikolai Piskunov, Tanja Ryabchikova
The characterization of exoplanet requires reliable determination of the fundamental parameters of their host stars. Spectral fitting plays an important role in this process. For t…
Non-LTE abundance corrections for late-type stars from 2000Å to 3μm: I. Na, Mg, and Al
K. Lind, T. Nordlander, A. Wehrhahn +6
It is well known that cool star atmospheres depart from local thermodynamic equilibrium (LTE). Accurate abundance determination requires taking those effects into account, but the…
