Solar Interior Rotation and its Variation
This article surveys the development of observational understanding of the interior rotation of the Sun and its temporal variation over approximately forty years, starting with the 1960s attempts to determine the solar core rotation from oblateness and proceeding through the development of helioseismology to the detailed modern picture of the internal rotation deduced from continuous helioseism...
متن کاملTemporal variations of the rotation rate in the solar interior
The temporal variations of the rotation rate in the solar interior are studied using frequency splittings from Global Oscillations Network Group (GONG) data obtained during the period 1995–99. We find alternating latitudinal bands of faster and slower rotation which appear to move towards the equator with time — similar to the torsional oscillations seen at the solar surface. This flow pattern ...
متن کاملTrends in rates of herpes zoster-related hospitalizations: are they real, are they costly, and are they linked to varicella vaccination?
To the Editor—We read with interest the article by Patel et al., who argue that their data suggest an increase in the incidence of herpes zoster (HZ) in the US population, as signaled by increases in rates of HZ-related hospital discharges; that the increase in the incidence of HZ is attributable to reduced circulation of the varicella zoster virus after initiation of varicella vaccination in c...
متن کاملLetter to the Editor Measurement of the electron temperature gradient in a solar coronal hole
It has long been established that the high speed solar wind streams observed at 1 A.U. originate from the coronal hole regions of the Sun. Theoretical modelling of the acceleration mechanism depends critically on the value of the maximum of temperature existing close to the Sun. Measurements of the temperature in coronal holes prior to SOHO are unreliable. The very low luminosity leads to extre...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
