Constraining the Physical Parameters of the Circumstellar Disk of chi Ophiuchi
C. Tycner, C. E. Jones, T. A. A. Sigut +4
We present a numerical model describing a circularly symmetric gaseous disk around the Be star chi Ophiuchi. The model is constrained by long-baseline interferometric observations…
A Parameter Study of Classical Be Star Disk Models Constrained by Optical Interferometry
C. E. Jones, C. Tycner, T. A. A. Sigut +2
We have computed theoretical models of circumstellar disks for the classical Be stars Dra, Psc, and Cyg. Models were constructed using a non-LTE radiative transf…
Infrared Excess in the Be Star Delta Scorpii
R. J. Halonen, C. E. Jones, T. A. A. Sigut +6
We present infrared photometric observations of the Be binary system delta Scorpii obtained in 2006. The J,H and K magnitudes are the same within the errors compared to observation…
The Thermal Structure of the Circumstellar Disk Surrounding the Classical Be Star gamma Cassiopeia
T. A. A. Sigut, C. E. Jones
We have computed radiative equilibrium models for the gas in the circumstellar envelope surrounding the hot, classical Be star Cassiopeia. This calculation is performed using a…
Molecular Hydrogen and [FeII] in Active Galactic Nuclei
Alberto Rodriguez-Ardila, Miriani G. Pastoriza, Sueli Viegas +2
(Abridge) Near-infrared spectroscopy is used to study the kinematics and excitation mechanisms of the H2 and [FeII] gas in a sample of AGN. The H2 lines are unresolved in all objec…
Magnetic topology and surface differential rotation on the K1 subgiant of the RS CVn system HR 1099
P. Petit, J. -F. Donati, G. A. Wade +8
We present here spectropolarimetric observations of the RS CVn system HR 1099 (V711 Tau) secured from 1998 February to 2002 January with the spectropolarimeter MuSiCoS at the Teles…
