Steady and Transient Radio Emission from Ultracool Dwarfs
R. A. Osten, N. Phan-Bao, S. L. Hawley +2
We detect radio emission in an additional two epochs of the ultracool dwarf binary LP 349- 25, finding that the observed emission is broadband and steady on timescales between 10s…
First Confirmed Detection of a Bipolar Molecular Outflow from a Young Brown Dwarf
Ngoc Phan-Bao, Basmah Riaz, Chin-Fei Lee +6
Studying the earliest stages in the birth of stars is crucial for understanding how they form. Brown dwarfs with masses between that of stars and planets are not massive enough to…
Simultaneous Multi-Wavelength Observations of Magnetic Activity in Ultracool Dwarfs. II. Mixed Trends in VB10 and LSR1835+32 and the Possible Role of Rotation
E. Berger, G. Basri, J. E. Gizis +8
[Abridged] As part of our on-going investigation of magnetic activity in ultracool dwarfs we present simultaneous radio, X-ray, UV, and optical observations of LSR1835+32 (M8.5), a…
Simultaneous Multi-Wavelength Observations of Magnetic Activity in Ultracool Dwarfs. I. The Complex Behavior of the M8.5 Dwarf TVLM513-46546
E. Berger, J. E. Gizis, M. S. Giampapa +8
[Abridged] We present the first simultaneous radio, X-ray, ultraviolet, and optical spectroscopic observations of the M8.5 dwarf TVLM513-46546, with a duration of 9 hours. These ob…
Discovery of new nearby L and late-M dwarfs at low Galactic latitude from the DENIS database
N. Phan-Bao, M. S. Bessell, E. L. Martin +9
We report new nearby L and late-M dwarfs (d_phot <= 30 pc) discovered in our search for nearby ultracool dwarfs (I-J >= 3.0, later than M8.0) at low Galactic latitude (|b| < 15 deg…
Discovery of Radio Emission from the Tight M8 Binary: LP 349-25
N. Phan-Bao, R. A. Osten, J. Lim +2
We present radio observations of 8 ultracool dwarfs with a narrow spectral type range (M8-M9.5) using the Very Large Array at 8.5 GHz. Only the tight M8 binary LP 349-25 was detect…
