The diameter of the CoRoT target HD 49933. Combining the 3D limb darkening, asteroseismology, and interferometry
L. Bigot, D. Mourard, P. Berio +21
Context. The interpretation of stellar pulsations in terms of internal structure depends on the knowledge of the fundamental stellar parameters. Long-base interferometers permit us…
Chromosphere of K giant stars Geometrical extent and spatial structure detection
P. Berio, T. Merle, F. Thevenin +19
We aim to constrain the geometrical extent of the chromosphere of non-binary K giant stars and detect any spatial structures in the chromosphere. We performed observations with the…
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…
Observing Compact Disks Inside Pre-Planetary Nebulae with the Very Large Telescope Interferometer
S. N. Bright, O. De Marco, O. Chesneau +3
AGB stars appear to lose mass spherically, but many PNe resulting from the AGB mass-loss have non-spherical morphologies. Compact disks have been found in some bipolar PNe, but the…
Penetrating the Homunculus -- Near-Infrared Adaptive Optics Images of Eta Carinae
Étienne Artigau, John C. Martin, Roberta M. Humphreys +3
Near-infrared adaptive optics imaging with NICI and NaCO reveal what appears to be a three-winged or lobed pattern, the "butterfly nebula", outlined by bright Br and H emi…
A mid-infrared imaging catalogue of post-AGB stars
Eric Lagadec, Tijl Verhoelst, Djamel Mekarnia +11
Post-AGB stars are key objects for the study of the dramatic morphological changes of low- to intermediate-mass stars on their evolution from the Asymptotic Giant Branch (AGB) towa…
VLTI observations of the dust geometry around R Coronae Borealis stars
S. N. Bright, O. Chesneau, G. C. Clayton +4
We are investigating the formation and evolution of dust around the hydrogen-deficient supergiants known as R Coronae Borealis (RCB) stars. We aim to determine the connection betwe…
The galactic unclassified B[e] star HD 50138. II. Interferometric constraints on the close circumstellar environment
Marcelo Borges Fernandes, Anthony Meilland, Philippe Bendjoya +7
HD 50138 is a southern star that presents the B[e] phenomenon, but its evolutionary stage is still not well known. This object presents spectral variability, which can be explained…
