WZ Sagittae as a DQ Herculis star
We argue that quiescent WZ Sge is a rapidly spinning magnetic rotator in which most of the matter transfered from the secondary is ejected from the system. Assuming that the observed 27.87 s oscillation period is due to the spinning white dwarf we propose that the other observed principal period of 28.96 s is a beat due to reprocessing of the rotating white dwarf beam on plasma blobs in Kepleri...
متن کاملUnusual State in V Sagittae
It has been recently demonstrated that the recurring high/low states in the peculiar binary V Sge can be explained by considering the limit-cycle oscillation involving negative feedback by the wind on the mass-transfer from the secondary star. We noticed, from the recent observations reported to the VSNET, the presence of a different state of recurring variations (recurrence time ∼ 30 d) showin...
متن کاملWZ Sagittae - an old dwarf nova
We model the evolution of the accretion disk of WZ Sagittae during the long quiescence. We find that the large amount of mass in the disk derived from the outburst luminosity is a severe constraint and demands values of αc ≈ 0.001 in contradiction to some recent suggestions. We include in our computations the formation of an inner disk hole and the growth of the disk due to redistribution of an...
متن کاملTackling Latency Using Fg
Applications that operate on datasets which are too big to fit in main memory, known in the literature as external-memory or out-of-core applications, store their data on one or more disks. Several of these applications make multiple passes over the data, where each pass reads data from disk, operates on it, and writes data back to disk. Compared with an in-memory operation, a disk-I/O operatio...
متن کاملنشانگان FG
هدف معرفی یک مورد نادر به نام نشانگان FG است که برای اولین بار در ایران گزارش می شود که به صورت عقب ماندگی ذهنی، هیپوتونی، ماکروسفالی، صورت مشخص و یبوست تظاهر می کند. این نشانگان مرتبط با کروموزوم X و مغلوب است. بیمار مورد نظر پسری 4 ساله است که به دلیل تب و تشنج مراجعه و در بیمارستان امام حسین (ع) بستری گردید. تشنج از نوع تونیک کولونیک و عمومی بوده و سابقه تشنج را از یکسالگی نیز داشته است فرزن...
