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…
Water vapor on supergiants. The 12 micron TEXES spectra of mu Cephei
N. Ryde, M. J. Richter, G. M. Harper +2
Several recent papers have argued for warm, semi-detached, molecular layers surrounding red giant and supergiant stars, a concept known as a MOLsphere. Spectroscopic and interferom…
Far-UV Emissions of the Sun in Time: Probing Solar Magnetic Activity and Effects on Evolution of Paleo-Planetary Atmospheres
Edward F. Guinan, Ignasi Ribas, Graham M. Harper
We present and analyze FUSE observations of six solar analogs. These are single, main-sequence G0-5 strs selected as proxies for the Sun at several stages of its main-sequence life…
Investigating a Possible Spectral Signature of the Wind-ISM Interaction Region of Alpha Tau
Brian E. Wood, Graham M. Harper, Hans-Reinhard Mueller +1
Ultraviolet spectra from the GHRS instrument on board the Hubble Space Telescope reveal the presence of a mysterious absorption feature in the Mg II h & k lines of the nearby (d=20…
