Towards measuring supermassive black hole masses with interferometric observations of the dust continuum

GRAVITY Collaboration, A. Amorim, G. Bourdarot +40

This work focuses on active galactic nuclei (AGNs), and the relation between the sizes of the hot dust continuum and the broad-line region (BLR). We find that the continuum size me…

The binary system of the spinning-top Be star Achernar

P. Kervella, S. Borgniet, A. Domiciano de Souza +16

Achernar, the closest and brightest classical Be star, presents rotational flattening, gravity darkening, occasional emission lines due to a gaseous disk, and an extended polar win…

The dust sublimation region of the Type 1 AGN NGC4151 at a hundred micro-arcsecond scale as resolved by the CHARA Array interferometer

Makoto Kishimoto, Matt Anderson, Theo ten Brummelaar +10

The nuclear region of Type 1 AGNs has only been partially resolved so far in the near-infrared (IR) where we expect to see the dust sublimation region and the nucleus directly with…

Smoke on the wind: dust nucleation in archetype colliding wind pinwheel WR104

A. Soulain, A. Lamberts, F. Millour +2

A handful of binary Wolf-Rayet stars are known to harbour spectacular spiral structures spanning a few hundred AU. These systems host some of the highest dust production rates in t…

Building a GRAVITY+ Adaptive Optics Test Bench

The Gravity Plus Consortium, Florentin Millour, Philippe Berio +22

We present the testbench aimed at integrating the GRAVITY+ adaptive optics GPAO. It consists of two independent elements, one reproducing the Coud{é} focus of the telescope, includ…

Locating dust and molecules in the inner circumstellar environment of R~Sculptoris with MATISSE

Julien Drevon, Florentin Millour, Pierre Cruzalèbes +49

AGB stars are one of the main sources of dust production in the Galaxy. However, it is not clear what this process looks like and where the dust is condensing in the circumstellar…
