Orbits, Distance, and Stellar Masses of the Massive Triple Star Sigma Orionis
G. H. Schaefer, C. A. Hummel, D. R. Gies +11
We present interferometric observations of the sigma Orionis triple system using the CHARA Array, NPOI, and VLTI. Using these measurements, we spatially resolve the orbit of the cl…
Surveying the Bright Stars by Optical Interferometry I: A Search for Multiplicity Among Stars of Spectral Types F - K
Donald Hutter, Robert Zavala, Christopher Tycner +5
We present the first results from an ongoing survey for multiplicity among the bright stars using the Navy Precision Optical Interferometer (NPOI). We first present a summary of NP…
Observing the PTPS Sample of Evolved Exoplanet Host Candidates Using the NPOI
Ellyn K. Baines, J. Thomas Armstrong, Henrique R. Schmitt +6
We plan to measure the angular diameters of a sample of Penn State-Torun Planet Search (PTPS) giant exoplanet host star candidates using the Navy Precision Optical Interferometer.…
Binary Black Holes, Gas Sloshing, and Cold Fronts in the X-ray Halo Hosting 4C+37.11
Felipe Andrade-Santos, Akos Bogdan, Roger W. Romani +5
We analyzed deep ACIS-I exposures of the cluster-scale X-ray halo surrounding the radio source 4C+37.11. This remarkable system hosts the closest resolved pair of super-m…
VISION: A Six-Telescope Fiber-Fed Visible Light Beam Combiner for the Navy Precision Optical Interferometer
Eugenio V. Garcia, Matthew W. Muterspaugh, Gerard van Belle +15
Visible-light long baseline interferometry holds the promise of advancing a number of important applications in fundamental astronomy, including the direct measurement of the angul…
