Dynamical Masses of T Tauri Stars and Calibration of Pre-Main-Sequence Evolution
We have used the high sensitivity and resolution of the IRAM interferometer to produce subarcsecond 12CO J = 2-1 images of nine protoplanetary disks surrounding T Tauri stars in the Taurus-AurigaExpand

COOL YOUNG STARS IN THE NORTHERN HEMISPHERE: β PICTORIS AND AB DORADUS MOVING GROUP CANDIDATES
As part of our continuing effort to identify new, low-mass members of nearby, young moving groups (NYMGs), we present a list of young, low-mass candidates in the northern hemisphere. We used ourExpand

THE Na 8200 Å DOUBLET AS AN AGE INDICATOR IN LOW-MASS STARS
We investigate the use of the gravity sensitive neutral sodium (Na I) doublet at 8183 A and 8195 A (Na 8200 A doublet) as an age indicator for M dwarfs. We measured the Na doublet equivalent widthExpand

LIKELY MEMBERS OF THE β PICTORIS AND AB DORADUS MOVING GROUPS IN THE NORTH
We present first results from follow-up of targets in the northern hemisphere {beta} Pictoris and AB Doradus moving group candidate list of Schlieder et al. We obtained high-resolution, near-infraredExpand

Periodic Accretion from a Circumbinary Disk in the Young Binary UZ Tau E
Close pre-main-sequence binary stars are expected to clear central holes in their protoplanetary disks, but the extent to which material can flow from the circumbinary disk across the gap onto theExpand

Adaptive Optics Imaging of the Orion Trapezium Cluster
We have imaged an area ~5 arcmin2 at the center of the Trapezium cluster in Orion in the K band using the University of Hawaii (UH) adaptive optics system at the UH 2.2 m telescope. Our surveyExpand

Mapping the Circumstellar Environment of T Tauri with Fluorescent H2 Emission
We have obtained three long-slit, far-UV spectra of the pre–main-sequence system T Tauri. These Hubble Space Telescope STIS spectra show a strong and variable on-source spectrum composed of bothExpand

Nearby Young Stars Selected by Proper Motion. I. Four New Members of the β Pictoris Moving Group From The Tycho-2 Catalog
We describe a procedure to identify stars from nearby moving groups and associations out of catalogs of stars with large proper motions. We show that from the mean motion vector of a known orExpand

β PICTORIS AND AB DORADUS MOVING GROUPS: LIKELY NEW LOW-MASS MEMBERS
We present results from our continuing program to identify new, low-mass, members of the nearby young moving groups (NYMGs) using a proper motion selection algorithm and various observationalExpand
