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…
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…
Chemical Abundances of Main-Sequence, Turn-off, Subgiant and red giant Stars from APOGEE spectra I: Signatures of Diffusion in the Open Cluster M67
Diogo Souto, Katia Cunha, Verne V. Smith +21
Detailed chemical abundance distributions for fourteen elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of…
