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…
Low-Mass Dwarf Template Spectra from the Sloan Digital Sky Survey
John J. Bochanski, Andrew A. West, Suzanne L. Hawley +1
We present template spectra of low-mass (M0-L0) dwarfs derived from over 4,000 Sloan Digital Sky Survey (SDSS) spectra. These composite spectra are suitable for use as medium-resol…
Meeting the Cool Neighbors. IX. The Luminosity Function of M7-L8 Ultracool Dwarfs in the Field
Kelle L. Cruz, I. Neill Reid, J. Davy Kirkpatrick +7
We present a 20-pc, volume-limited sample of M7-L8 dwarfs created through spectroscopic follow-up of sources selected from the Two Micron All Sky Survey (2MASS) Second Incremental…
Using the Galactic Dynamics of M7 Dwarfs to Infer the Evolution of Their Magnetic Activity
Andrew A. West, John J. Bochanski, Suzanne L. Hawley +5
We present a spectroscopic study and dynamical analysis of ~2600 M7 dwarfs. We confirm our previous finding that the fraction of magnetically active stars decreases with vertical d…
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…
