Mapping stellar surfaces III: An Efficient, Scalable, and Open-Source Doppler Imaging Model
Rodrigo Luger, Megan Bedell, Daniel Foreman-Mackey +3
The study of stellar surfaces can reveal information about the chemical composition, interior structure, and magnetic properties of stars. It is also critical to the detection and…
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…
EXPRES. II. Searching for Planets Around Active Stars: A Case Study of HD 101501
Samuel H. C. Cabot, Rachael M. Roettenbacher, Gregory W. Henry +7
By controlling instrumental errors to below 10 cm/s, the EXtreme PREcision Spectrograph (EXPRES) allows for a more insightful study of photospheric velocities that can mask weak Ke…
Excalibur: A Non-Parametric, Hierarchical Wavelength-Calibration Method for a Precision Spectrograph
L. L. Zhao, D. W. Hogg, M. Bedell +1
Excalibur is a non-parametric, hierarchical framework for precision wavelength-calibration of spectrographs. It is designed with the needs of extreme-precision radial velocity (EPR…
EXPRES I. HD~3651 an Ideal RV Benchmark
John M. Brewer, Debra A. Fischer, Ryan T. Blackman +10
The next generation of exoplanet-hunting spectrographs should deliver up to an order of magnitude improvement in radial velocity precision over the standard 1 m/s state of the art.…
A Hermite-Gaussian Based Radial Velocity Estimation Method
Parker Holzer, Jessi Cisewski-Kehe, Debra Fischer +1
As the first successful technique used to detect exoplanets orbiting distant stars, the Radial Velocity Method aims to detect a periodic Doppler shift in a star's spectrum. We intr…
