Improving the Precision of Line-by-Line Radial Velocities: A Data-Driven Iterative Algorithm for Spectral Line Selection
Kanishk Pandey, Eric A. Ford, Joseph M. Salzer +17
Independent analysis of individual spectral lines, or line-by-line (LBL) analyses, can improve upon standard cross-correlation function (CCF) methods for measuring radial velocitie…
GJ 523b is a Massive, 170 Myr-old Mega-Earth, Likely on a Polar Orbit
Maxwell A. Kroft, Thomas G. Beatty, Joseph M. Salzer +18
We use WIYN/NEID radial velocity measurements to confirm the planetary nature and measure the mass of the TESS transiting exoplanet candidate around the mid-K dwarf GJ 523 ($V=9.23…
Searching for Low-Mass Exoplanets Amid Stellar Variability with a Fixed Effects Linear Model of Line-by-Line Shape Changes
Joseph Salzer, Jessi Cisewski-Kehe, Eric B. Ford +1
The radial velocity (RV) method, also known as Doppler spectroscopy, is a powerful technique for exoplanet discovery and characterization. In recent years, progress has been made t…
Accounting for stellar activity signals in radial-velocity data by using Change Point Detection techniques
U. Simola, A. Bonfanti, X. Dumusque +3
Active regions on the photosphere of a star have been the major obstacle for detecting Earth-like exoplanets using the radial velocity (RV) method. A commonly employed solution for…
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…
