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…
The Spectrum of Thorium from 250 nm to 5500 nm: Ritz Wavelengths and Optimized Energy Levels
Stephen L. Redman, Gillian Nave, Craig J. Sansonetti
We have made precise observations of a thorium-argon hollow cathode lamp emission spectrum in the region between 350 nm and 1175 nm using a high-resolution Fourier transform spectr…
A near infrared frequency comb for Y+J band astronomical spectroscopy
Steve Osterman, Gabriel G. Ycas, Scott A. Diddams +8
Radial velocity (RV) surveys supported by high precision wavelength references (notably ThAr lamps and I2 cells) have successfully identified hundreds of exoplanets; however, as th…
Optical fiber modal noise in the 0.8 to 1.5 micron region and implications for near infrared precision radial velocity measurements
Keegan McCoy, Lawrence Ramsey, Suvrath Mahadevan +2
Modal noise in fibers has been shown to limit the signal-to-noise ratio achievable in fiber-coupled, high-resolution spectrographs if it is not mitigated via modal scrambling techn…
Development of a New, Precise Near-infrared Doppler Wavelength Reference: A Fiber Fabry-Perot Interferometer
Samuel Halverson, Suvrath Mahadevan, Lawrence Ramsey +5
We present the ongoing development of a commercially available Micron Optics fiber-Fabry Perot Interferometer as a precise, stable, easy to use, and economic spectrograph reference…
The Habitable-Zone Planet Finder: A Stabilized Fiber-Fed NIR Spectrograph for the Hobby-Eberly Telescope
Suvrath Mahadevan, Lawrence Ramsey, Chad Bender +12
We present the scientific motivation and conceptual design for the recently funded Habitable-zone Planet Finder (HPF), a stabilized fiber-fed near-infrared (NIR) spectrograph for t…
