Measured spectral shifts due to intrinsic stellar variability (eg, pulsations, granulation) and
activity (eg, spots, plages) are the largest source of error for extreme-precision radial-velocity …

To date, only 18 exoplanets with radial velocity (RV) semi-amplitude< 2 ms− 1 have had
their masses directly constrained. The biggest obstacle to RV detection of such exoplanets is …

With dedicated exoplanet surveys underway for multiple extreme-precision radial velocity
(EPRV) instruments, the near-future prospects of RV exoplanet science are promising …

The radial velocity (RV) detection of exoplanets is challenged by stellar spectroscopic
variability that can mimic the presence of planets and by instrumental instability that can …

We present the results of Sun-as-a-star observations by the NEID Solar Telescope at WIYN
Observatory, spanning January 1, 2021 through June 30, 2024. We identify 117,060 …

A time-delay embedding (TDE), grounded in the framework of Takens's Theorem, provides a
mechanism to represent and analyze the inherent dynamics of time-series data. Recently …

For many decades, cross-correlating spectral data with a template mask has been the
standard approach to radial velocity (RV) extraction for exoplanet detection. In this proof-of …

The discovery of the first extra-solar planet was a breakthrough that revolutionized our
understanding of the Universe. The increasing number of planets discovered combined with …

The field of exoplanets is currently poised to benefit hugely from improved radial velocity
(RV) precision. Extreme precision radial-velocity (EPRV) measurements, capable of …

A quarter century after the famous discovery of 51 Peg b, the radial velocity (RV) method
remains a key exoplanet detection and characterisation method. For transiting planets, RVs …
