“The life cycles of Be star disks”

ABSTRACT

Be stars are main sequence objects surrounded by a gaseous disk ejected by the star itself. Although the ejection mechanism is not yet fully understood, it is partially credited to the close to critical rotation observed in these objects. In this talk, I will present our recent results about the life cycles of these viscous disks, based on the interpretation of the infrared SED of 80 Be stars. Finally, I will show the preliminary results of our current work, in which we observed 22 objects in high angular resolution using infrared interferometry.

STUDENTS – after the talk, you’re encouraged to return to the 2nd floor Atrium lounge to meet with the speaker.
COFFEE – coffee and cookies will be available in the 2nd floor Atrium lounge at 1:15 p.m.
CELL PHONES – as a courtesy to the speaker and audience, please set your cellphones to “silent” mode. Thanks!
