The long-period Galactic Cepheid RS Puppis - I. A geometric distance from its light echoes
Pierre Kervella, Antoine Mérand, Laszlo Szabados +4
Context: The bright southern Cepheid RS Pup is surrounded by a circumstellar nebula reflecting the light from the central star. The propagation of the light variations from the Cep…
The environment of the fast rotating star Achernar - High-resolution thermal infrared imaging with VISIR in BURST mode
Pierre Kervella, Armando Domiciano De Souza
Context: The geometry of the circumstellar envelopes (CSE) surrounding Be stars is still uncertain, although it is often assumed that they are formed by a disk around the stellar e…
Eta Car through the eyes of interferometers
Olivier Chesneau, R. Van Boekel, T. Herbst +6
The core of the nebula surrounding Eta Carinae has recently been observed with VLT/NACO, VLTI/VINCI, VLTI/MIDI and VLTI/AMBER in order to spatially and spectrally constrain the war…
VLTI/VINCI observations of the nucleus of NGC 1068 using the adaptive optics system MACAO
M. Wittkowski, P. Kervella, R. Arsenault +3
We present the first near-infrared K-band long-baseline interferometric measurement of the prototype Seyfert 2 galaxy NGC 1068 with resolution lambda/B \~ 10 mas obtained with the…
Modeling of Alpha Cen and Procyon using VLTI observations
P. Kervella, F. Thevenin, P. Morel +4
We present a novel approach to model the nearby stars Alpha Cen A & B and Procyon A using asteroseismic and interferometric constraints. Using the VINCI instrument installed at the…
Tests of stellar model atmospheres by optical interferometry: VLTI/VINCI limb-darkening measurements of the M4 giant psi phe
M. Wittkowski, J. P. Aufdenberg, P. Kervella
We present K-band interferometric measurements of the limb-darkened intensity profile of the M4 giant star psi Phoenicis obtained with VLTI/VINCI. High-precision squared visibility…
