Correcting stellar contamination in transmission spectroscopy with contemporaneous monitoring: Application to GJ 1214 b
Ò. Porqueras-León, M. Perger, J. C. Morales +19
Transmission spectroscopy has emerged as an essential tool for characterising the atmospheres of transiting exoplanets. However, stellar surface inhomogeneities contaminate transmi…
Decoding the Radial Velocity Signatures of Solar Faculae with 3D MHD Simulations
Florian Kröll, Sowmya Krishnamurthy, Alexander Shapiro +8
We model the solar radial velocity (RV) signal induced by faculae, the dominant contributor to RV variability in Sun-like stars. We use a representative case of a facular patch tra…
Deciphering transmission spectra by exploring the solar paradigm
Nina-Elisabeth Nèmec, Òscar Porqueras- Léon, Ignasi Ribas +1
Transmission spectroscopy probes exoplanet atmospheres via the wavelength dependence of transit depths, but stellar contamination from magnetic activity can significantly bias thes…
Forward modelling of brightness variations in Sun-like stars -- II. Light curves and variability
N. -E. Nèmec, A. I. Shapiro, E. Işik +2
The amplitude and morphology of light curves of solar-like stars change substantially with increasing rotation rate: brightness variations get amplified and become more regular, wh…
Faculae cancel out on the surfaces of active Suns
N. -E. Nèmec, A. I. Shapiro, E. Işık +5
Surfaces of the Sun and other cool stars are filled with magnetic fields, which are either seen as dark compact spots or more diffuse bright structures like faculae. Both hamper de…
Predictions of Astrometric Jitter for Sun-like Stars. III. Fast Rotators
K. Sowmya, N. -E. Nèmec, A. I. Shapiro +3
A breakthrough in exoplanet detections is foreseen with the unprecedented astrometric measurement capabilities offered by instrumentation aboard Gaia space observatory. Besides, as…
