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…
