Spiral Structure in Ip Pegasi; How Persistent Is It?
Figure 4. Trailed spectrograms (top panels), Doppler maps (middle panels) and computed data (bottom panels) are plotted for Hβ, He ii λ4686Å, and He i λ4472Å for both nights. The computed data were reconstructed from the Doppler maps. The letters A, B and C mark flares visible in both Hβ and He ii λ4686Å; these lead to some artifacts (diagonal stripes) in the maps. ABSTRACT We present spectrosc...
متن کاملSpiral structure in the accretion disc of the binary IP Pegasi
We have found the first convincing evidence for spiral structure in the accretion disc of a close binary. The eclipsing dwarf nova binary IP Peg, observed during the end phase of a rise to outburst, shows strong Balmer and Helium emission lines in its spectra, with asymmetric double peaked velocity profiles produced in the accretion disc around the white dwarf. To reveal the two armed spiral on...
متن کاملSimulations of spiral structure in the accretion disc of IP Pegasi during outburst
We consider the implications of the detection of spiral structure in the accretion disc of the binary IP Pegasi. We use numerical simulations of the development of a disc outburst to construct predicted Doppler tomograms, which are found to be in close agreement with the observations if the spiral pattern arises as a transient feature when the disc expands viscously at the start of the outburst...
متن کاملPlatelet Refractoriness and how it is formed
Abstract Background and Objectives Transfusion of platelet has become one of the main treatments for thrombocytopenic patients to reduce the severity and frequency of bleeding consequences. Failure to attain the desired level of platelets in a patient following platelet transfusion is defined as platelet refractoriness. The purpose of present paper is to review and study the mechanisms involve...
متن کاملPatient Safety Behavior in Physicians: How is it Predicted?
Background: Patient safety is a serious global public health issue. Estimates show that every day many patients are harmed while receiving hospital care. Health care staff plays a key role in providing quality and safe patient care, especially physicians who are main members of the medical team and a critical element in patient safety efforts. Objective: ...
