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…
On-sky observations with an achromatic hybrid phase knife coronagraph in the visible
Lyu Abe, Mathilde Beaulieu, Farrokh Vakili +4
CONTEXT: The four-quadrant phase mask stellar coronagraph, introduced by D. Rouan et al., is capable of achieving very high dynamical range imaging and was studied in the context o…
Achernar Can be a Differential Rotator
Juan Zorec, Armando Domiciano De Souza, Yves Fremat +1
We take advantage of interferometric measurements of Achernar to inquire on its internal rotational law. The reinterpretation of interferome-tric data and the use of fundamental pa…
