Line-by-line velocity measurements, an outlier-resistant method for precision velocimetry
Étienne Artigau, Charles Cadieux, Neil J. Cook +14
We present a new algorithm for precision radial velocity (pRV) measurements, a line-by-line (LBL) approach designed to handle outlying spectral information in a simple but efficien…
Optical and Near-Infrared Radial Velocity Content of M Dwarfs: Testing Models with Barnard's Star
Étienne Artigau, Lison Malo, René Doyon +3
High precision radial velocity (RV) measurements have been central in the study of exoplanets during the last two decades, from the early discovery of hot Jupiters, to the recent m…
Telluric-line subtraction in high-accuracy velocimetry: a PCA-based approach
Étienne Artigau, Nicola Astudillo-Defru, Xavier Delfosse +8
Optical velocimetry has led to the detection of more than 500 planets to date and there is a strong effort to push m/s velocimetry to the near-infrared to access cooler and lighter…
