The case for optical interferometric polarimetry

Nicholas M. Elias, Carol E. Jones, Henrique R. Schmitt +3

Within the last 10 years, long-baseline optical interferometry (LBOI) has benefited significantly from increased sensitivity, spatial resolution, and spectral resolution, e.g., mea…

delta Cen: a new binary Be star detected by VLTI/AMBER spectro-interferometry

Anthony Meilland, Florentin Millour, Philippe Stee +5

We study the Be star Cen circumstellar disk using long-baseline interferometry which is the only observing technique capable of resolving spatially and spectroscopically object…
