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…
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 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…
Retrieval of Precise Radial Velocities from Near-Infrared High Resolution Spectra of Low Mass Stars
Peter Gao, Peter Plavchan, Jonathan Gagné +21
Given that low-mass stars have intrinsically low luminosities at optical wavelengths and a propensity for stellar activity, it is advantageous for radial velocity (RV) surveys of t…
Discovery And Characterization of Wide Binary Systems With a Very Low Mass Component
Frédérique Baron, David Lafrenière, Étienne Artigau +7
We report the discovery of 14 low-mass binary systems containing mid-M to mid-L dwarf companions with separations larger than 250 AU. We also report the independent discovery of 9…
A 3D Search for Companions to 12 Nearby M-Dwarfs
Cassy L. Davison, Russel J. White, Todd J. Henry +7
We present a carefully vetted equatorial ( 30 Decl.) sample of all known single (within 4'') mid M-dwarfs (M2.5V-M8.0V) extending out to 10 pc; their proximity and low…
The Solar Neighborhood. XXXIII. Parallax Results from the CTIOPI 0.9m Program: Trigonometric Parallaxes of Nearby Low-Mass Active and Young Systems
Adric R. Riedel, Charlie T. Finch, Todd J. Henry +14
We present basic observational data and association membership analysis for 45 young and active low-mass stellar systems from the ongoing RECONS photometry and astrometry program a…
The Closest M-Dwarf Quadruple System to the Sun
Cassy L. Davison, Russel J. White, Wei-Chun Jao +8
We report new infrared radial velocity measurements obtained with CSHELL at NASA's Infrared Telescope Facility that reveal the M3.5 dwarf GJ 867B to be a single-lined spectroscopic…
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…
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…
Design and Construction of Absorption Cells for Precision Radial Velocities in the K Band using Methane Isotopologues
Guillem Anglada-Escudé, Peter Plavchan, Sean Mills +11
We present a method to optimize absorption cells for precise wavelength calibration in the near-infrared. We apply it to design and optimize methane isotopologue cells for precisio…
