Multiepoch Radial Velocity Observations of L Dwarfs
ASTROPHYSICAL JOURNAL, no. 2 (2007): 1198-1204
Abstract
We report on the development of a technique for precise radial velocity measurements of cool stars and brown dwarfs in the near infrared. Our technique is analogous to the iodine (I-2) absorption cell method that has proven so successful in the optical regime. We rely on telluric CH4 absorption features to serve as a wavelength reference,...More
