X-Raying a Be star disk: fundamental parameters of the eclipsing binary Be star V658 Car
Tajan H. de Amorim, Alex C. Carciofi, Jonathan Labadie-Bartz +8
With its two stellar eclipses and two disk attenuations per binary orbit, V658 Carinae stands out as the first clear eclipsing Be + sdOB system. This rare alignment offers a unique…
A Spitzer-IRS Detection of Crystalline Silicates in a Protostellar Envelope
Charles A. Poteet, S. Thomas Megeath, Dan M. Watson +12
We present the Spitzer Space Telescope Infrared Spectrograph spectrum of the Orion A protostar HOPS-68. The mid-infrared spectrum reveals crystalline substructure at 11.1, 16.1, 18…
Achernar: Rapid Polarization Variability as Evidence of Photospheric and Circumstellar Activity
A. C. Carciofi, A. M. Magalhães, N. V. Leister +2
We present the results of a high accuracy () polarization monitoring of the Be Star Achernar that was carried out between July 7th and November 5th, 2006. Our resu…
The Role of Evolutionary Age and Metallicity in the Formation of Classical Be Circumstellar Disks II. Assessing the Evolutionary Nature of Candidate Disk Systems
John P. Wisniewski, Karen S. Bjorkman, Antonio M. Magalhaes +3
(Abridged version) We present the first detailed imaging polarization observations of six SMC and six LMC clusters, known to have large populations of B-type stars which exhibit ex…
Observations and modeling of the inner disk region of T Tauri stars
R. L. Akeson, C. H. Walker, K. Wood +7
We present observations of four T Tauri stars using long baseline infrared interferometry from the Palomar Testbed Interferometer. The target sources, T Tau N, SU Aur, RY Tau and D…
