The inner disk of RY Tau: evidence of stellar occultation by the disk atmosphere at the sublimation rim from K-band continuum interferometry
Claire L. Davies, Stefan Kraus, Tim J. Harries +13
We present models of the inner region of the circumstellar disk of RY Tau which aim to explain our near-infrared (-band: m) interferometric observations while remaining…
Probing the Inner Disk Emission of the Herbig Ae Stars HD 163296 and HD 190073
Benjamin R. Setterholm, John D. Monnier, Claire L. Davies +16
The physical processes occurring within the inner few astronomical units of proto-planetary disks surrounding Herbig Ae stars are crucial to setting the environment in which the ou…
A multi-instrument and multi-wavelength high angular resolution study of MWC614: quantum heated particles inside the disk cavity
Jacques Kluska, Stefan Kraus, Claire L. Davies +13
High angular resolution observations of young stellar objects are required to study the inner astronomical units of protoplanetary disks in which the majority of planets form. As t…
The H-band Emitting Region of the Luminous Blue Variable P Cygni: Spectrophotometry and Interferometry of the Wind
N. D. Richardson, G. H. Schaefer, D. R. Gies +20
We present the first high angular resolution observations in the nearinfrared H-band (1.6 microns) of the Luminous Blue Variable star P Cygni. We obtained six-telescope interferome…
A CHARA Array Survey of Circumstellar Disks around Nearby Be-type Stars
Y. Touhami, D. R. Gies, G. H. Schaefer +11
We report on a high angular resolution survey of circumstellar disks around 24 northern sky Be stars. The K-band continuum survey was made using the CHARA Array long baseline inter…
FUV Detection of the Suspected Subdwarf Companion to the Be Star 59 Cygni
Geraldine J. Peters, Tiffany D. Pewett, Douglas R. Gies +2
We report on the detection of a hot subdwarf component in the Be binary system, 59 Cygni. The spectral signature is found in cross-correlation functions of photospheric model spect…
Stellar Diameters and Temperatures I. Main Sequence A, F, & G Stars
Tabetha S. Boyajian, Harold A. McAlister, Gerard van Belle +15
We have executed a survey of nearby, main sequence A, F, and G-type stars with the CHARA Array, successfully measuring the angular diameters of fortyfour stars with an average prec…
The 2011 outburst of the recurrent novaT Pyx. Evidence for a face-on bipolar ejection
Olivier Chesneau, A. Meilland, D. P. K. Banerjee +19
We report on near-IR interferometric observations of the outburst of the recurrent nova T Pyx. We obtained near-IR observations of T Pyx at dates ranging from t=2.37d to t=48.2d af…
Gas Distribution, Kinematics, and Excitation Structure in the Disks around the Classical Be Stars Beta Canis Minoris and Zeta Tauri
Stefan Kraus, John D. Monnier, Xiao Che +11
Using CHARA and VLTI near-infrared spectro-interferometry with hectometric baseline lengths (up to 330m) and with high spectral resolution (up to 12000), we studied the gas distrib…
The Infrared Continuum Sizes of Be Star Disks
Y. Touhami, D. R. Gies, G. H. Schaefer
We present an analysis of the near-infrared continuum emission from the circumstellar gas disks of Be stars using a radiative transfer code for a parametrized version of the viscou…
Multi-epoch Near-Infrared Interferometry of the Spatially Resolved Disk Around the Be Star Zeta Tau
G. H. Schaefer, D. R. Gies, J. D. Monnier +14
We present interferometric observations of the Be star Zeta Tau obtained using the MIRC beam combiner at the CHARA Array. We resolved the disk during four epochs in 2007-2009. We f…
The Be Star HD 215227: A Candidate Gamma-ray Binary
S. J. Williams, D. R. Gies, R. A. Matson +4
The emission-line Be star HD 215227 lies within the positional error circle of the newly identified gamma-ray source AGL J2241+4454. We present new blue spectra of the star, and we…
Spectro-interferometry of the Be star delta Sco: Near-Infrared Continuum and Gas Emission Region Sizes in 2007
