Towards Understanding Stellar Radial Velocity Jitter as a Function of Wavelength: The Sun as a Proxy
Robert C. Marchwinski, Suvrath Mahadevan, Paul Robertson +2
Using solar spectral irradiance measurements from the SORCE spacecraft and the F/F' technique, we have estimated the radial velocity (RV) scatter induced on the Sun by stellar acti…
The Habitable-zone Planet Finder Calibration System
Samuel Halverson, Suvrath Mahadevan, Lawrence Ramsey +9
We present the design concept of the wavelength calibration system for the Habitable-zone Planet Finder instrument (HPF), a precision radial velocity (RV) spectrograph designed to…
Development of Fiber Fabry-Perot Interferometers as Stable Near-infrared Calibration Sources for High Resolution Spectrographs
Samuel Halverson, Suvrath Mahadevan, Lawrence Ramsey +10
We discuss the ongoing development of single-mode fiber Fabry-Perot (FFP) Interferometers as precise astro-photonic calibration sources for high precision radial velocity (RV) spec…
Suppression of Fiber Modal Noise Induced Radial Velocity Errors for Bright Emission-Line Calibration Sources
Suvrath Mahadevan, Samuel Halverson, Lawrence Ramsey +1
Modal noise in optical fibers imposes limits on the signal to noise and velocity precision achievable with the next generation of astronomical spectrographs. This is an increasingl…
