Spectral Line Depth Variability in Radial Velocity Spectra
Alexander Wise, Peter Plavchan, Xavier Dumusque +2
Stellar active regions, including spots and faculae, can create radial velocity (RV) signals that interfere with the detection and mass measurements of low mass exoplanets. In doin…
Stellar activity correction using PCA decomposition of shells
M. Cretignier, X. Dumusque, F. Pepe
Context. Stellar activity and instrumental signals are the main limitations to the detection of Earth-like planets using the radial velocity (RV) technique. Recent studies show tha…
A candidate short-period sub-Earth orbiting Proxima Centauri
J. P. Faria, A. Suárez Mascareño, P. Figueira +34
Proxima Centauri is the closest star to the Sun. This small, low-mass, mid M dwarf is known to host an Earth-mass exoplanet with an orbital period of 11.2 days within the habitable…
The EXPRES Stellar Signals Project II. State of the Field in Disentangling Photospheric Velocities
Lily L. Zhao, Debra A. Fischer, Eric B. Ford +40
Measured spectral shifts due to intrinsic stellar variability (e.g., pulsations, granulation) and activity (e.g., spots, plages) are the largest source of error for extreme precisi…
Investigating the architecture and internal structure of the TOI-561 system planets with CHEOPS, HARPS-N and TESS
G. Lacedelli, T. G. Wilson, L. Malavolta +115
We present a precise characterization of the TOI-561 planetary system obtained by combining previously published data with TESS and CHEOPS photometry, and a new set of HARPS-N…
