A public interferometric survey of the gaseous circumstellar environments of hot stars is being conducted. It is named OHANA тАФ the Observatory survey at High ANgular resolution of Active OB stars. The survey is a bad weather/filler programme currently carried out by the VLTI group at the Paranal Observatory.
Public VLTI Survey of Environments of Early-type Stars
Published: 28 Nov 2013
The targets are selected from three classes: Be stars; supergiants and LBVs; and interacting binaries. The data are taken with the AMBER instrument in its high spectral resolution setting (R=12000). The data are available immediately through the ESO archive under programme 092.D-0289. Quick-look reductions are published soon after and can be obtained from a dedicated forum.
