The HD 163296 Circumstellar Disk in Scattered Light: Evidence of Time-Variable Self-Shadowing
John P. Wisniewski, Mark Clampin, Carol A. Grady +6
We present the first multi-color view of the scattered light disk of the Herbig Ae star HD 163296, based on coronagraphic observations from the Hubble Space Telescope Advanced Came…
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…

Cindy R. Tam, Fotis P. Gavriil, Rim Dib +3
(Abridged) We report on new and archival X-ray and near-infrared observations of the anomalous X-ray pulsar 1E 1048.1-5937 performed between 2001-2007 with RXTE, CXO, Swift, HST, a…
The Magnetic Field Structure of the LMC 2 Supershell: NGC 2100
John P. Wisniewski, Karen S. Bjorkman, Antonio M. Magalhaes +2
We present U,B,V,R,I imaging polarimetry of NGC 2100 and its surrounding environment, which comprise a part of the LMC 2 supershell. The morphology of the observed position angle d…
