Rushton, M. T., Kaminsky, B., Lynch, D. K., Pavlenko, Ya. V., Evans, A., Eyres, S. P. S., ...
We present near infrared spectroscopy of the recurrent nova RS Oph obtained on several occasions after its latest outburst in 2006 February. The 1-5 mircon spectra are dominated by the red giant, but...
The disk and environment of a young Altair analog: SAO 206462 (2009)
Grady, C. A., Schneider, G., Sitko, M. L., Williger, G. M., Hamaguchi, K., Brittain, S. D., ...
Proto-planetary and transitional disks which are detected in scattered light provide a critical test of the interpretation of circumstellar disks based on the IR spectral energy distribution (SED)...
Sitko, M. L., Carpenter, W. J., Kimes, R. L., Wilde, J. L., Lynch, D. K., Russell, R. W., ...
Infrared photometry and spectroscopy covering a time span of a quarter century are presented for HD 31648 (MWC 480) and HD 163296 (MWC 275). Both are isolated Herbig Ae stars that exhibit signs of...
THE STAR-GRAZING EXTRA-SOLAR COMETS IN THE HD 100546 SYSTEM (2007)
C. A. Grady, M. L. Sitko, Karen S. Bjorkman, Mario R. P Erez, D. K. Lynch, R. W. Russell, ...
Redshifted, absorption profiles resembling the high velocity circumstellar gas features in the spectrum of fi Pic have been detected in IUE data for the 2 Myr-old Herbig Be star, HD 100546, on 1995...
The disk and environment of a young Vega analog: HD 169142 (2007)
Grady, C. A., Schneider, G., Hamaguchi, K., Sitko, M. L., Carpenter, W. J., Hines, D., ...
We trace the disk of HD 169142 (A8 Ve) from 0.57" to 1.4" (~80-200 AU projected distance) in 1.1 mum scattered light with HST NICMOS coronagraphy. The azimuthally symmetric disk has a peak...

We trace the disk of HD 169142 (A8Ve) from 0.57 ′ ′ to 1.4 ′ ′ (≈80-200 AU projected distance) in 1.1µm scattered light with HST/NICMOS coronagraphy. The azimuthally-symmetric disk has a...
Mid-Infrared Ethane Emission on Neptune and Uranus (2006)
Hammel, H. B., Lynch, D. K., Russell, R. W., Sitko, M. L., Bernstein, L. S., Hewagama, T.
We report 8- to 13-micron spectral observations of Neptune and Uranus from the NASA Infrared Telescope Facility spanning more than a decade. The spectroscopic data indicate a steady increase in...

Cutri, R., Lynch, D. K., Rudy, R. J., Russell, R. W., Rice, C. J., Mazuk, S., ...
This paper talks about infrared spectroscopy.
FUSE Spectroscopy of the Two Prototype White Dwarfs With Signatures of a Super-hot Wind (2002)
Werner, K., Dreizler, S., Kruk, J. W., Sitko, M. L.
The O VIII phenomenon describes the occurrence of ultra-high ionization absorption lines of the CNO elements (e.g. O VIII, N VII, C VI, and even Ne X) in the optical spectra hot of DO WDs.
Hines, D. C., Schmidt, G. D., Gordon, K. D., Smith, P. S., Wills, B. J., Allen, R. G., ...
We present UV and optical spectropolarimetry of two highly polarized IRAS-selected QSOs, IRAS 13349+2438 and the BALQSO IRAS 14026+4341. The polarization in both objects rises rapidly toward the...
Silicate Emission in the TW Hydrae Association (2000)
Sitko, M. L., Lynch, D. K., Russell, R. W
The TW Hydrae Association is the nearest young stellar association. Among its members are HD 98800, HR 4796A, and TW Hydrae itself, the nearest known classical T Tauri star. We have observed these...
