Journal ArticleDOI
A disk asymmetry in motion around the B[e] star MWC158
Jacques Kluska,Myriam Benisty,Ferréol Soulez,Jean-Philippe Berger,J.-B. Le Bouquin,Fabien Malbet,Bernard Lazareff,Éric Thiébaut +7 more
TL;DR: In this article, the authors investigated the origin of the variability within the inner astronomical unit of the central star using near-infrared interfero-metric observations with PIONIER over a two-year period.
Journal ArticleDOI
The Pulsation of Chi Cygni Imaged by Optical Interferometry; a Novel Technique to Derive Distance and Mass of Mira Stars

TL;DR: In this article, the S-type Mira star Chi Cygni was observed at four different epochs in 2005-2006 with the IOTA optical interferometer (H band) and images showed up to 40% variation in the stellar diameter, as well as significant changes in the limb darkening and stellar inhomogeneities.
Proceedings ArticleDOI
The 2012 interferometric imaging beauty contest
Fabien Baron,W. D. Cotton,Peter R. Lawson,S. T. Ridgway,Alicia Aarnio,John D. Monnier,Karl Heinz Hofmann,Dieter Schertl,G. Weigelt,Éric Thiébaut,Ferréol Soulez,David Mary,Florentin Millour,Martin Vannier,John Young,N. M. Elias,Henrique R. Schmitt,Sridharan Rengaswamy +17 more
TL;DR: The fifth Interferometric Imaging Beauty Contest consists in blind imaging of test data sets derived from model sources and distributed in the OIFITS format and the results of the image reconstruction obtained by each method are discussed.
Proceedings ArticleDOI
2008 imaging beauty contest

TL;DR: A formal comparison is presented of the performance of algorithms used for imaging data from optical/infrared long-baseline interferometers using the OI-FITS format.
Proceedings ArticleDOI

TL;DR: This process has shown that new comers can use publicly-available imaging software to interpret VLTI/PIONIER imaging data, as long as sufficient observations are taken to have complete uv coverage { a luxury that is often missing}, and urges proposers to request adequate observing nights to collect sufficient data for imaging and for time allocation committees to recognise the importance of uv Coverage.
