Gas and grain chemistry in a protoplanetary disk The chemistry in a protoplanetary accretion disk is modelled between a radius of 100 and 0.1 AU of the central object. We find that interaction of the gas ... K Willacy,HH Klahr,TJ Millar,... - 《Astronomy & Astrophysics》 被引量: 164...
IL:Probably that private education in Estonia is uncommon – less than 5% of students go to private schools. So parents think “private school” means a paradise school with no problems. The challenge was that in the beginning we were a normal school with the same challenges and growing pains...
(au), and these distances can involve a lot of zeros. using scientific notation makes these calculations much more manageable. does scientific notation have applications in computing? scientific notation is often used in computing and programming, especially when dealing with very large or very small...
Qualitatively, a planetary magnetosphere is the volume of space from which the solar wind is excluded by a planet's magnetic field. (A schematic illustration of the terrestrial magnetosphere is given in Fig. 1, which shows how the solar wind is diverted around the magnetopause, a surface that...
Copper chemistry is remarkably complex. Just to give you an idea, the chloride ions play an important role in this reaction. E.g. if you do the same with hydrogen peroxide and dilute sulphuric acid, then you'll see that the reaction is much slower. The special thing is that Cu2+ ...
