Precision near-infrared radial velocity instrumentation I: Absorption Gas Cells
Peter P. Plavchan, Guillem Anglada-Escude, Russel White +18
We have built and commissioned gas absorption cells for precision spectroscopic radial velocity measurements in the near-infrared in the H and K bands. We describe the construction…
A High-Precision NIR Survey for RV Variable Low-Mass Stars
Jonathan Gagné, Peter Plavchan, Peter Gao +26
We present the results of a precise near-infrared (NIR) radial velocity (RV) survey of 32 low-mass stars with spectral types K2-M4 using CSHELL at the NASA IRTF in the -band wit…
Precise Near-Infrared Radial Velocities
Peter Plavchan, Peter Gao, Jonathan Gagne +31
We present the results of two 2.3 micron near-infrared radial velocity surveys to detect exoplanets around 36 nearby and young M dwarfs. We use the CSHELL spectrograph (R ~46,000)…
A planet within the debris disk around the pre-main-sequence star AU Microscopii
Peter Plavchan, Thomas Barclay, Jonathan Gagné +84
AU Microscopii (AU Mic) is the second closest pre main sequence star, at a distance of 9.79 parsecs and with an age of 22 million years. AU Mic possesses a relatively rare and spat…
APF - The Lick Observatory Automated Planet Finder
Steven S. Vogt, Matthew Radovan, Robert Kibrick +45
The Automated Planet Finder (APF) is a facility purpose-built for the discovery and characterization of extrasolar planets through high-cadence Doppler velocimetry of the reflex ba…
Precision near-infrared radial velocity instrumentation II: Non-Circular Core Fiber Scrambler
Peter P. Plavchan, Michael Bottom, Peter Gao +18
We have built and commissioned a prototype agitated non-circular core fiber scrambler for precision spectroscopic radial velocity measurements in the near-infrared H band. We have…
