| Abstract: |
The NIRSPEC Brown Dwarf Spectroscopic Survey (BDSS) was initiated in 1999 by Ian McLean (UCLA) and Davy Kirkpatrick (IPAC) following deployment of NIRSPEC to Keck II and the discovery of brown dwarf candidates in the Two Micron All Sky Survey (2MASS). High quality near-infrared spectra for a large sample of M, L, and T dwarfs have been obtained by many members of the BDSS team since inception of the project. Moderate-resolution (R∼2,000) near-IR spectra include over 200 objects (approximately 20% field M dwarfs, 30% young M dwarfs, 10% M giants, 30% L dwarfs, and 10% T dwarfs). These medium-resolution data products include J-band (1.143–1.375 micron) coverage for every object and broader coverage (0.96–2.31 micron) for about 30 targets. High-resolution (R∼20,000) spectra consist primarily of cross-dispersed J-band (1.165–1.323 micron) observations, resulting in eight dispersion orders for ∼70 objects (approximately 15% field M dwarfs, 40% young M dwarfs, 25% L dwarfs, and 20% T dwarfs). The BDSS Online Archive (BDSSarchive.org) described in this poster is a catalog of all observed objects, with published data available as reduced and extracted ascii files. Unpublished data are also available upon request. Other database updates, including a mutable table and links to reductions for multiple observational epochs, will be implemented in the near future. The sample size, wavelength coverage, spectral resolution, and high quality data makes the BDSS Online Archive a premier library of brown dwarf medium-to-high resolution near-infrared spectra. |
