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…
Nonthermal Hard X-ray Emission and Iron Kalpha Emission from a Superflare on II Pegasi
R. A. Osten, S. Drake, J. Tueller +4
We report on an X-ray flare detected on the active binary system II~Pegasi with the Swift telescope. The trigger had a 10-200 keV luminosity of 2.2 erg s-- a…
Radio Constraints on Activity in Young Brown Dwarfs
R. A. Osten, R. Jayawardhana
We report on searches for radio emission from three of the nearest known young brown dwarfs using the Very Large Array. We have obtained sensitive upper limits on 3.6cm emission fr…
From Radio to X-ray: The Quiescent Atmosphere of the dMe Flare Star EV Lacertae
R. A. Osten, S. L. Hawley, J. Allred +3
We report on multi-wavelength observations spanning radio to X-ray wavelengths of the M dwarf flare star, EV Lacertae, probing the characteristics of the outer atmospheric plasma f…
