The Disk Population of the Taurus Star-Forming Region
We have analyzed nearly all images of the Taurus star-forming region at 3.6, 4.5, 5.8, 8.0, and 24??m that were obtained during the cryogenic mission of the Spitzer Space Telescope (46 deg2) and haveExpand

THE DISK POPULATION OF THE CHAMAELEON I STAR-FORMING REGION
We present a census of circumstellar disks in the Chamaeleon I star-forming region. Using the Infrared Array Camera and the Multiband Imaging Photometer on board the Spitzer Space Telescope, we haveExpand

Meeting the Cool Neighbors. IX. The Luminosity Function of M7-L8 Ultracool Dwarfs in the Field
We present a 20 pc, volume-limited sample of M7YL8 dwarfs created through spectroscopic follow-up of sources selected from the Two Micron All Sky Survey Second Incremental Release Point SourceExpand

Star Formation via the Little Guy: A Bayesian Study of Ultracool Dwarf Imaging Surveys for Companions
I have undertaken a comprehensive statistical investigation of the ultracool dwarf companion distribution (spectral type M6 and later). Utilizing a Bayesian algorithm, I tested models of theExpand

THE SUBSTELLAR MASS FUNCTION: A BAYESIAN APPROACH
We report our efforts to constrain the form of the low-mass star and brown dwarf mass function via Bayesian inference. Recent surveys of M, L, and T dwarfs in the local solar neighborhood are anExpand

An Infrared/X-ray Survey for New Members of the Taurus Star-Forming Region
We present the results of a search for new members of the Taurus star-forming region using data from the Spitzer Space Telescope and the XMM-Newton Observatory. We have obtained optical andExpand

MEETING THE COOL NEIGHBORS. VIII. A PRELIMINARY 20 PARSEC CENSUS FROM THE NLTT CATALOGUE
Continuing our census of late-type dwarfs in the solar neighborhood, we present BVRI photometry and optical spectroscopy of 800 mid-type M dwarfs drawn from the NLTT proper-motion catalog. TheExpand

A new brown dwarf desert? A scarcity of wide ultracool binaries
We present the results of a deep-imaging search for wide companions to low-mass stars and brown dwarfs using NSFCam on the Infrared Telescope Facility. We searched a sample of 132 M7-L8 dwarfs toExpand
