The TEXES Survey For H2 Emission From Protoplanetary Disks
M. A. Bitner, M. J. Richter, J. H. Lacy +9
We report the results of a search for pure rotational molecular hydrogen emission from the circumstellar environments of young stellar objects with disks using the Texas Echelon Cr…
Mg I emission lines at 12 and 18 micrometer in K giants
J. O. Sundqvist, N. Ryde, G. M. Harper +2
The solar Mg I emission lines at 12 micrometer have already been observed and analyzed well. Previous modeling attempts for other stars have, however, been made only for Procyon an…
A potential new method for determining the temperature of cool stars
S. Viti, H. R. A. Jones, M. J. Richter +3
We present high resolution (R = 90,000) mid-infrared spectra of M dwarfs. The mid infrared region of the spectra of cool low mass stars contain pure rotational water vapour transit…
TEXES Observations of Pure Rotational H2 Emission From AB Aurigae
M. A. Bitner, M. J. Richter, J. H. Lacy +3
We present observations of pure rotational molecular hydrogen emission from the Herbig Ae star, AB Aurigae. Our observations were made using the Texas Echelon Cross Echelle Spectro…
High Resolution Mid-Infrared Imaging of Radio Ultra-Compact HII Regions
Uriel Giveon, Matthew J. Richter, Robert H. Becker +1
We present data from mid-infrared Keck Telescope imaging of 18 radio-selected ultra-compact HII region candidates at diffraction-limited resolution. The goal of these observations…
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…
