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…
Spectro-interferometric observations of classical nova V458 Vul 2007
Samira Rajabi, Matthew W. Muterspaugh, Benjamin F. Lane +6
We used the Palomar Testbed Interferometer (PTI) to resolve 2.2 m emission from the classical nova V458 Vul 2007 over the course of several days following its discovery on 2007…
