Near-Ultraviolet Spectra of Flares on YZ CMi
Suzanne L. Hawley, Lucianne M. Walkowicz, Joel C. Allred +1
Near-ultraviolet spectroscopic data obtained with the HST STIS instrument on the dMe flare star YZ Canis Minoris (YZ CMi) were analyzed. Flare and quiet intervals were identified f…
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…
Radiative Hydrodynamic Models of Optical and Ultraviolet Emission from M Dwarf Flares
Joel C. Allred, Suzanne L. Hawley, William P. Abbett +1
We report on radiative hydrodynamic simulations of M dwarf stellar flares and compare the model predictions to observations of several flares. The flares were simulated by calculat…
Optical Spectroscopy of a Flare on Barnard's Star
D. Paulson, J. Allred, R. Anderson +3
We present optical spectra of a flare on Barnard's star. Several photospheric as well as chromospheric species were enhanced by the flare heating. An analysis of the Balmer lines s…
Radiative Hydrodynamic Models of the Optical and Ultraviolet Emission from Solar Flares
J. C. Allred, S. L. Hawley, W. P. Abbett +1
We report on radiative hydrodynamic simulations of moderate and strong solar flares. The flares were simulated by calculating the atmospheric response to a beam of non-thermal elec…
From Radio to X-ray: Flares on the dMe Flare Star EV Lacertae
R. A. Osten, S. L. Hawley, J. C. Allred +2
We present the results of a campaign to observe flares on the M dwarf flare star EV Lacertae over the course of two days in 2001 September, utilizing a combination of radio continu…
