Gamma rays from halos around stars and the Sun
Inverse Compton (IC) scattering by relativis-tic electrons produces a major component of the diffuse emission from the Galaxy. The photon fields involved are the cosmic microwave background and the interstel-lar radiation field (ISRF) from stars and dust. We expect which could be detectable by instruments such as GLAST. Even individual nearby luminous stars could be detectable assuming just the...

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 کاملDetecting transits from Earth-sized planets around Sun-like stars
Context. Detecting regular dips in the light curve of a star is an easy way to detect the presence of an orbiting planet. CoRoT is a Franco-European mission launched at the end of 2006, and one of its main objectives is to detect planetary systems using the transit method. Aims. In this paper, we present a new method for transit detection and determine the smallest detected planetary radius, as...
متن کاملMeyerson phenomenon around naevi: resolution after sun exposure?
Meyerson phenomenon (MP) is an inflammatory, some times itchy, eczematous eruption usually encircling a pre-existing melanocytic naevus. The terms halo derma-titis and Meyerson's naevus are also frequently used to describe it (1). MP usually appears in otherwise healthy young male individuals, but has also been reported in females and young children (2). Apart from slight itching, no other sym...
متن کاملTransience of Hot Dust around Sun-like Stars
There is currently debate over whether the dust content of planetary systems is stochastically regenerated or originates in planetesimal belts evolving in quasi-steady state. In this paper a simple model for the steady state evolution of debris disks due to collisions is developed and confronted with the properties of the emerging population of 7 sun-like stars that have hot dust at < 10 AU. Th...
