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…

A Stellar Activity F-statistic for Exoplanet Surveys (SAFE)

Parker H. Holzer, Jessi Cisewski-Kehe, Lily Zhao +3

In the search for planets orbiting distant stars the presence of stellar activity in the atmospheres of observed stars can obscure the radial velocity signal used to detect such pl…

Stability Constrained Characterization of Multiplanet Systems

Daniel Tamayo, Christian Gilbertson, Daniel Foreman-Mackey

Many discovered multiplanet systems are tightly packed. This implies that wide parameter ranges in masses and orbital elements can be dynamically unstable and ruled out. We present…

Toward Extremely Precise Radial Velocities: II. A Tool For Using Multivariate Gaussian Processes to Model Stellar Activity

Christian Gilbertson, Eric B. Ford, David E. Jones +1

The radial velocity method is one of the most successful techniques for the discovery and characterization of exoplanets. Modern spectrographs promise measurement precision of ~0.2…

Predicting the long-term stability of compact multiplanet systems

Daniel Tamayo, Miles Cranmer, Samuel Hadden +11

We combine analytical understanding of resonant dynamics in two-planet systems with machine learning techniques to train a model capable of robustly classifying stability in compac…

Towards Extremely Precise Radial Velocities: I. Simulated Solar Spectra for Testing Exoplanet Detection Algorithms

Christian Gilbertson, Eric B. Ford, Xavier Dumusque

Recent and upcoming stabilized spectrographs are pushing the frontier for Doppler spectroscopy to detect and characterize low-mass planets. Specifications for these instruments are…
