Near-Contemporaneous Optical Spectroscopic and Infrared Photometric Observations of Candidate Herbig Ae/Be Stars in the Magellanic Clouds
Bradley W. Rush, John P. Wisniewski, Karen S. Bjorkman
We present near-IR (J,H,Ks) photometry for 27 of the 28 candidate Herbig Ae/Be stars in the Small and Large Magellanic Clouds identified via the EROS1 and EROS2 surveys as well as…
A New Diagnostic of the Radial Density Structure of Be Disks
Zachary H. Draper, John P. Wisniewski, Karen S. Bjorkman +5
We analyze the intrinsic polarization of two classical Be stars in the process of losing their circumstellar disks via a Be to normal B star transition originally reported by Wisni…
Disk-Loss and Disk Renewal Phases in Classical Be Stars II. Detailed Analysis of Spectropolarimetric Data
Zachary H. Draper, John P. Wisniewski, Karen S. Bjorkman +4
In Wisniewski et al. 2010, paper I, we analyzed 15 years of spectroscopic and spectropolarimetric data from the Ritter and Pine Bluff Observatories of 2 Be stars, 60 Cygni and π Aq…
