Statistical Analysis of Interferometric Measurements of Axis Ratios for Classical Be Stars
Richard P. Cyr, Carol E. Jones, Christopher Tycner
This work presents a novel method to estimate the effective opening angle of CBe star disks from projected axis ratio measurements, obtained by interferometry using Bayesian statis…
Fundamental Parameters of 87 Stars from the Navy Precision Optical Interferometer
Ellyn K. Baines, J. Thomas Armstrong, Henrique R. Schmitt +5
We present the fundamental properties of 87 stars based on angular diameter measurements from the Navy Precision Optical Interferometer, 36 of which have not been measured previous…
Properties of the H-alpha-emitting Circumstellar Regions of Be Stars
Christopher Tycner, John B. Lester, Arsen R. Hajian +6
Long-baseline interferometric observations obtained with the Navy Prototype Optical Interferometer of the H-alpha-emitting envelopes of the Be stars eta Tauri and beta Canis Minori…
Spiral Density Enhancements in Be Binary Systems
Isabelle H. Cyr, Carol E. Jones, Alex C. Carciofi +3
We use a smoothed particle hydrodynamics (SPH) code to examine the effects of a binary companion on a Be star disk for a range of disk viscosities and misalignment angles, i.e. the…
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…
The DDO IVC Distance Project: Survey Description and the Distance to G139.6+47.6
Christopher R. Burns, Christopher Tycner, Megan McClure +4
We present a detailed analysis of the distance determination for one intermediate Velocity Cloud (IVC G139.6+47.6) from the ongoing DDO IVC Distance Project. Stars along the line o…
