Navy Prototype Optical Interferometer Imaging of Line Emission Regions of beta Lyrae Using Differential Phase Referencing
H. R. Schmitt, T. A. Pauls, C. Tycner +9
We present the results of an experiment to image the interacting binary star beta Lyrae with data from the Navy Prototype Optical Interferometer (NPOI), using a differential phase…
Turbulence Time Series Data Hole Filling using Karhunen-Loeve and ARIMA methods
M. P. J. L. Chang, H. Nazari, C. O. Font +2
Measurements of optical turbulence time series data using unattended instruments over long time intervals inevitably lead to data drop-outs or degraded signals. We present a compar…
Humidity's influence on visible region refractive index structure parameter
Mark P. J. L. Chang, Carlos O. Font, G. Charmaine Gilbreath +1
In the infrared and visible bandpass, optical propagation theory conventionally assumes that humidity does not contribute to the effects of atmospheric turbulence on optical beams.…
Vega is a rapidly rotating star
D. M. Peterson, C. A. Hummel, T. A. Pauls +8
Vega, the second brightest star in the northern hemisphere, serves as a primary spectral type standard. While its spectrum is dominated by broad hydrogen lines, the narrower lines…
Constraining Disk Parameters of Be Stars using Narrowband H-alpha Interferometry with the NPOI
C. Tycner, G. C. Gilbreath, R. T. Zavala +7
Interferometric observations of two well-known Be stars, gamma Cas and phi Per, were collected and analyzed to determine the spatial characteristics of their circumstellar regions.…
Resolving the Effects of Rotation in Altair with Long-Baseline Interferometry
D. M. Peterson, C. A. Hummel, T. A. Pauls +7
We report successful fitting of a Roche model, with a surface temperature gradient following the von Zeipel gravity darkening law, to observations of Altair made with the Navy Prot…
