Evidence for localized onset of episodic mass loss in Mira
G. Perrin, S. T. Ridgway, S. Lacour +9
We report Multi-telescope interferometric measurements taken with the Interferometric Optical Telescope Array (IOTA) to provide imagery of the LPV Mira in the H-band. This waveleng…
The Pulsation of Chi Cygni Imaged by Optical Interferometry; a Novel Technique to Derive Distance and Mass of Mira Stars
S. Lacour, E. Thiébaut, G. Perrin +13
We present infrared interferometric imaging of the S-type Mira star Chi Cygni. The object was observed at four different epochs in 2005-2006 with the IOTA optical interferometer (H…
Detection of non-radial pulsation and faint companion in the symbiotic star CH Cyg
E. Pedretti, J. D. Monnier, S. Lacour +10
We have detected asymmetry in the symbiotic star CH Cyg through the measurement of precision closure-phase with the IONIC beam combiner, at the IOTA interferometer. The position of…
The limb-darkened Arcturus; Imaging with the IOTA/IONIC interferometer
S. Lacour, S. Meimon, E. Thiebaut +14
This paper is an H band interferometric examination of Arcturus, a star frequently used as a spatial and spectral calibrator. Using the IOTA 3 telescope interferometer, we performe…
First Images of R Aquarii and its Asymmetric HO Shell
S. Ragland, H. Le Coroller, E. Pluzhnik +7
We report imaging observations of the symbotic long-period Mira variable R Aquarii (R Aqr) at near-infrared and radio wavelengths. The near-infrared observations were made with the…
Physical Orbit for Lambda Virginis and a Test of Stellar Evolution Models
M. Zhao, J. D. Monnier, G. Torres +12
Lambda Virginis (LamVir) is a well-known double-lined spectroscopic Am binary with the interesting property that both stars are very similar in abundance but one is sharp-lined and…
