Tomographic Simulations of Accretion Disks in Cataclysmic Variables - Flickering and Wind
Both continuum and emission line flickering are phenomena directly associated
with the mass accretion process. In this work we simulate accretion disk
Doppler maps including the effects of winds and flickering flares. Synthetic
flickering Doppler maps are calculated and the effect of the flickering
parameters on the maps is explored. Jets and winds occur in many astrophysical
objects where accretion disks are present. Jets are generally absent among the
cataclysmic variables (CVs), but there is evidence of mass loss by wind in many
objects. CVs are ideal objects to study accretion disks and consequently to
study the wind associated with these disks. We also present simulations of
accretion disks including the presence of a wind with orbital phase resolution.
Synthetic H-alpha line profiles in the optical region are obtained and their
corresponding Doppler maps are calculated. The effect of the wind simulation
parameters on the wind line profiles is also explored. From this study we
verified that optically thick lines and/or emission by diffuse material into
the primary Roche lobe are necessary to generate single peaked line profiles,
often seen in CVs. The future accounting of these effects is suggested for
interpreting Doppler tomography reconstructions.Comment: 9 pages, 9 figure
