Imaging the spotty surface of Betelgeuse in the H band
X. Haubois, G. Perrin, S. Lacour +9
This paper reports on H-band interferometric observations of Betelgeuse made at the three-telescope interferometer IOTA. We image Betelgeuse and its asymmetries to understand the s…
A binary engine fuelling HD87643' s complex circumstellar environment, using AMBER/VLTI
Florentin Millour, Olivier Chesneau, Marcelo Borges Fernandes +19
Context. The star HD 87643, exhibiting the "B[e] phenomenon", has one of the most extreme infrared excesses for this object class. It harbours a large amount of both hot and cold d…
Pre-maximum spectro-imaging of the Mira star T Lep with AMBER/VLTI
Jean-Baptiste Le Bouquin, Sylvestre Lacour, Stephanie Renard +3
Diffuse envelopes around Mira variables are among the most important sources influencing the chemical evolution of galaxies. However they represent an observational challenge becau…
ASKI: full-sky lensing map making algorithms
C. Pichon, E. Thiebaut, S. Prunet +4
Within the context of upcoming full-sky lensing surveys, the edge-preserving non- linear algorithm Aski is presented. Using the framework of Maximum A Posteriori inversion, it aims…
