STIS Imaging of the HR 4796A Circumstellar Debris Ring
G. Schneider, A. J. Weinberger, E. E. Becklin +2
We have obtained high spatial resolution imaging observations of the HR 4796A circumstellar debris dust ring using the broad optical response of the Hubble Space Telescope Imaging…
Complex Organic Materials in the Circumstellar Disk of HR 4796A
J. H. Debes, A. J. Weinberger, G. Schneider
We combine HST/NICMOS imaging photometry of the HR 4796A disk at previously unobserved wavelengths between 1.71-2.22\micron with reprocessed archival observations to produce a meas…
The Effect of the Transit of Venus on ACRIM's Total Solar Irradiance Measurements: Implications for Transit Studies of Extrasolar Planets
G. Schneider, J. M. Pasachoff, R. C. Willson
We used the 8 June 2004 transit of Venus (ToV) as a surrogate to test observing methods, strategies and techniques that are being contemplated for future space missions to detect a…
High Spatial Resolution HST/NICMOS Observations of Markarian 231
F. J. Low, G. Schneider, G. Neugebauer
Observations of Markarian 231 at 1.1 microns taken with NICMOS on the Hubble Space Telescope are described. The brightness of the object in the near infrared and the inherent short…
