The kinematics of very low mass dwarfs: splinter session summary
Adam J. Burgasser, Jacqueline K. Faherty, Sarah Schmidt +10
Kinematic investigations are being increasingly deployed in studies of the lowest mass stars and brown dwarfs to investigate their origins, characterize their atmospheres, and exam…
The L dwarf/T dwarf transition: multiplicity, magnetic activity and mineral meteorology across the hydrogen burning limit
Adam J. Burgasser
The transition between the L dwarf and T dwarf spectral classes is one of the most remarkable along the stellar/brown dwarf Main Sequence, separating sources with photospheres cont…
Extremely metal-poor gas at a redshift of 7
Robert A. Simcoe, Peter W. Sullivan, Kathy L. Cooksey +3
In typical astrophysical environments, the abundance of heavy elements ranges from 0.001 to 2 times the solar concentration. Lower abundances have been seen in select stars in the…
Science with the Murchison Widefield Array
Judd D. Bowman, Iver Cairns, David L. Kaplan +58
Significant new opportunities for astrophysics and cosmology have been identified at low radio frequencies. The Murchison Widefield Array is the first telescope in the Southern Hem…
Detection of Radio Emission from the Hyperactive L Dwarf 2MASS J13153094-2649513AB
Adam J. Burgasser, Carl Melis, B. Ashley Zauderer +1
We report the detection of radio emission from the unusually active L5e + T7 binary 2MASS J13153094-2649513AB made with the Australian Telescope Compact Array. Observations at 5.5…
Keck NIRSPEC Radial Velocity Observations of Late-M dwarfs
Angelle Tanner, Russel White, John Bailey +5
We present the results of an infrared spectroscopic survey of 23 late-M dwarfs with the NIRSPEC echelle spectrometer on the Keck II telescope. Using telluric lines for wavelength c…
