VLTI/AMBER differential interferometry of the broad-line region of the quasar 3C273
Romain G. Petrov, Florentin. Millour, Stéphane Lagarde +4
Unveiling the structure of the Broad Line Region (BLR) of AGNs is critical to understand the quasar phenomenon. Resolving a few BLRs by optical interferometry will bring decisive i…
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…
V838 Monocerotis: the central star and its environment a decade after outburst
Olivier Chesneau, Florentin Millour, Orsola De Marco +8
Aims. V838 Monocerotis erupted in 2002, brightened in a series of outbursts, and eventually developed a spectacular light echo. A very red star emerged a few months after the outbu…
Optical interferometry and adaptive optics of bright transients
Florentin Millour, Olivier Chesneau, Anthony Meilland +1
Bright optical transients (i.e. transients typically visible with the naked eye) are populated mainly by novae eruptions plus a few supernovae (among which the SN1987a event). One…
Statistical characterization of polychromatic absolute and differential squared visibilities obtained from AMBER/VLTI instrument
Antony Schutz, Martin Vannier, David Mary +3
In optical interferometry, the visibility squared modulus are generally assumed to follow a Gaussian distribution and to be independent of each other. A quantitative analysis of th…
DISCO: a Spatio-Spectral Recombiner for Pupil Remapping Interferometry
Florentin Millour, Romain Petrov, Stéphane Lagarde +3
Pupil-remapping is a new high-dynamic range imaging technique that has recently demonstrated feasibility on sky. The current prototypes present however deceiving limiting magnitude…
