Multiband GPI Imaging of the HR 4796A Debris Disk
Christine H. Chen, Johan Mazoyer, Charles A. Poteet +36
We have obtained Gemini Planet Imager (GPI) J-, H-, K1-, and K2-Spec observations of the iconic debris ring around the young, main-sequence star HR 4796A. We applied several point-…
The Gemini Planet Imager view of the HD 32297 debris disk
Gaspard Duchene, Malena Rice, Justin Hom +60
We present new -band scattered light images of the HD 32297 edge-on debris disk obtained with the Gemini Planet Imager (GPI). The disk is detected in total and polarized intensi…
Dynamical Evolution of Viscous Disks around Be Stars. II : polarimetry
Xavier Haubois, Bruno C. Mota, Alex C. Carciofi +4
Be stars exhibit variability for a great number of observables. Putting the pieces together of the disk dynamics is not an easy task and requires arduous modeling before achieving…
Disk-Loss and Disk-Renewal Phases in Classical Be Stars II. Contrasting with Stable and Variable Disks
Zachary H. Draper, John P. Wisniewski, Karen S. Bjorkman +5
Recent observational and theoretical studies of classical Be stars have established the utility of polarization color diagrams (PCD) in helping to constrain the time-dependent mass…
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…
Disk Loss and Disk Renewal Phases in Classical Be Stars I: Analysis of Long-Term Spectropolarimetric Data
John P. Wisniewski, Zachary H. Draper, Karen S. Bjorkman +3
(Abridged) Classical Be stars occasionally transition from having a gaseous circumstellar disk (''Be phase'') to a state in which all observational evidence for the presence of the…
