"The Latest on 'Be' Stars"

Jon Bartz, Lehigh University

So-called "Be stars" are massive, rapidly rotating, pulsating stars that occasionally eject mass from their surface, which then forms a disk. I will present recent results that describe the behavior of hundreds of these systems on timescales from hours to years.

Jonathan Labadie-Bartz is a 5th year graduate student at Lehigh University, whose research interests include massive stars and discovering "Hot Jupiter" exoplanets with the KELT collaboration. His dissertation work involves studying large numbers of "Be stars", which are massive and highly variable.

The :LVAAS July General Meeting is a "pot-luck" picnic, with burgers, hot dogs, and beverages supplied by LVAAS. Please plan to bring a covered dish, dessert, or snack to share. The event is scheduled for Saturday, but may be rescheduled for Sunday in the event of bad weather. If this occurs, an email will be sent to members in addition to announcement on this page.

THE LEHIGH VALLEY AMATEUR ASTRONOMICAL SOCIETY -- 620B East Rock Road -- Allentown, PA 18103 -- 610-797-3476 --


Founded in 1957, the Lehigh Valley Amateur Astronomical Society (LVAAS) is one of the oldest continuously-operating amateur astronomy organizations in the U.S. The mission of LVAAS is to promote the study of Astronomy and to maintain a meeting space, observatories, and a planetarium.

LVAAS operates two astronomy sites: The South Mountain site in Salisbury Township is the headquarters of the Society. It has a planetarium with a Spitz A3P projector, a 21 foot dome, meeting space, the Red Shift store, library, workshop space, and three observatories. The Pulpit Rock site near Hamburg is LVAAS's members-only dark sky site. At 1600 feet above sea level, the site features five observatories and a pad for member's scopes.

Members who receive training on the scopes may obtain keys to the observatories. LVAAS also maintains a rental "fleet" of telescopes that members may rent at low cost. Members also receive access to The Observer, our online newsletter, as well as reduced subscription prices to Sky and Telescope and Astronomy Magazine. If you want to learn more about astronomy and LVAAS, please join us at our next public star party.
