Non-LTE Monte Carlo Radiative Transfer: II. Non-Isothermal Solutions for Viscous Keplerian Disks
A. C. Carciofi, J. E. Bjorkman
We discuss the basic hydrodynamics that determines the density structure of the disks around hot stars. Observational evidence supports the idea that these disks are Keplerian (rot…
On the Determination of the Rotational Oblateness of Achernar
A. C. Carciofi, A. Domiciano de Souza, A. M. Magalhaes +2
The recent interferometric study of Achernar, leading to the conclusion that its geometrical oblateness cannot be explained in the Roche approximation, has stirred substantial inte…
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…
Modeling the Structure of Hot Star Disks: a Critical Evaluation of the Viscous Decretion Scenario
A. C. Carciofi, J. E. Bjorkman, A. S. Miroshnichenko +2
We present self-consistent solutions for the disk structure of classical Be stars. Our disk model is hydrostatically supported in the vertical direction and the radial structure is…
Polarimetry and the Envelopes of Magellanic B[e] Supergiants
A. M. Magalhaes, R. Melgarejo, A. Pereyra +1
We discuss the nature of the circumstellar envelopes around the B[e] supergiants (B[e]SG) in the Magellanic Clouds (MC). Contrary to those in the Galaxy, the MC B[e]SG have a well…
The Polarization Signature of Extrasolar Planets Transiting Cool Dwarfs
A. C. Carciofi, A. M. Magalhaes
We investigate the linear polarization in the light of extrasolar planetary systems that may arise as a result of an occultation of the star by a transiting planet. Such an occulta…
