Image modeling of compact starburst clusters: I. R136
Zeinab Khorrami, Farrokh Vakili, Olivier Chesneau
Continuous progress in data quality from HST, recent multiwavelength high resolution spectroscopy and high contrast imaging from ground adaptive optics on large telescopes need mod…
Pseudomagnitudes and Differential Surface Brightness: Application to the apparent diameter of stars
Alain Chelli, Gilles Duvert, Laurent Bourgès +4
The diameter of a star is a major observable that serves to test the validity of stellar structure theories. It is also a difficult observable that is mostly obtained with indirect…
VLT/SPHERE deep insight of NGC 3603's core: Segregation or confusion?
Z. Khorrami, T. Lanz, F. Vakili +19
We present new near-infrared photometric measurements of the core of the young massive cluster NGC 3603 obtained with extreme adaptive optics. The data were obtained with the SPHER…
Observations of binaries in AGB, post-AGB stars and Planetary Nebulae
Eric Lagadec, Olivier Chesneau
During the last years, many observational studies have revealed that binaries play an active role in the shaping of non spherical planetary nebulae. We review the different works t…
Improving the surface brightness-color relation for early-type stars using optical interferometry
M. Challouf, N. Nardetto, D. Mourard +18
The aim of this work is to improve the SBC relation for early-type stars in the color domain, using optical interferometry. Observations of eight B- and A-type…
The RCB star V854 Cen is surrounded by a hot dusty shell
Olivier Chesneau, Florentin Millour, Orsola De Marco +5
Aims : The hydrogen-deficient supergiants known as R Coronae Borealis (RCB) stars might be the result of a double-degenerate merger of two white dwarfs (WDs), or a final helium she…
