Effect of stellar spot-only spectral lines in high-resolution transit spectroscopy
W. Dethier, E. Cristo, O. D. S. Demangeon +3
We investigate how a representative single spectral line present only in a stellar spot can introduce distortions in high-resolution planetary absorption spectra. Specifically, we…
The impact of interpolation in high-resolution spectroscopy -- The overlooked role of interpolation in radial velocity extraction
A. M. Silva, D. Doshi, K. Al Moulla +11
We explore the impact of spectral interpolation in radial velocity (RV) time-series extracted through template-based methods. We build synthetic datasets with Gaussian profiles to…
Precise measurement of WASP-31 b's Rossiter-McLaughlin effect and characterization of the planet transmission spectra
M. Steiner, V. Bourrier, D. Ehrenreich +23
Context. Hot Jupiters are ideal natural laboratories to investigate atmospheric composition and dynamics. However, high-resolution transmission spectroscopy is currently limited by…
SOAPv4: A new step toward modeling stellar signatures in exoplanet research
E. Cristo, J. P. Faria, N. C. Santos +6
We present and describe a new version of the spot oscillation and planet code, SOAPv4. Our aim is to demonstrate its capabilities in modeling stellar activity in the context of RV…
A systematic bias in template-based RV extraction algorithms
André M. Silva, N. C. Santos, J. P. Faria +30
In this paper we identify and explore a previously unidentified, multi meter-per-second, systematic correlation between time and RVs inferred through TM and LBL methods. We evaluat…
The ESPRESSO transmission spectrum of HD189733b : Extracting the planetary sodium and lithium signatures amid stellar contamination
D. Mounzer, W. Dethier, C. Lovis +20
While transmission spectroscopy has allowed us to detect many atomic and molecular species in exoplanet atmospheres, the improvement in resolution and signal-to-noise ratio enabled…
