Comparison of Interplanetary Disturbances at the near Spacecraft with Coronal Mass Ejections at the Sun
We examined interplanetary magnetic field disturbances recorded at the NEARShoemaker spacecraft when it was above either the east or west solar limb as seen from Earth, and then we identified the associated coronal mass ejections (CMEs) detected above the limbs by the SOHO/LASCO coronagraph. We found 10 cases where a nonrecurring IP disturbance could be associated with a CME. Eight of the distu...
متن کاملEvolution of Near-Sun Solar Wind Turbulence
This paper presents a preliminary analysis of the turbulence spectrum of the solar wind in the near-Sun region R < 50R⊙, obtained from interplanetary scintillation measurements with the Ooty Radio Telescope at 327 MHz. The results clearly show that the scintillation is dominated by density irregularities of size about 100 − 500 km. The scintillation at the small-scale side of the spectrum, alth...

سرطانهای جلدی را می توان به انواع پیش بدخیم و بدخیم تقسیم نمود. شایعترین ضایعه جلدی پیش بدخیم، کراتوز آفتابی نام دارد که بصورت ضایعات خشک و دلمه دار جلدی بروز می کنند - لنتیگو آفتابی یک ضایعه پیش بدخیم دیگرن است که بصورت لکه های قهوه ای و صاف (غیر برجسته روی پوست مشاهده می شوند) ضایعات پیش بدخیم در صورت عدم درمان می توانند بدخیم شوند.
متن کاملRing diagram analysis of near - surface flows in the Sun
Ring diagram analysis of solar oscillation power spectra obtained from MDI data is carried out to study the velocity fields in the outer part of the solar convection zone. The three dimensional power spectra are fitted to a model which has a Lorentzian profile in frequency and which includes the advection of the wave front by horizontal flows, to obtain the two components of the sub-surface flo...
متن کاملThe Science of Sungrazers, Sunskirters, and Other Near-Sun Comets
This review addresses our current understanding of comets that venture close to the Sun, and are hence exposed to much more extreme conditions than comets that are typically studied from Earth. The extreme solar heating and plasma environments that these objects encounter change many aspects of their behaviour, thus yielding valuable information on both the comets themselves that complements ot...
