the vast majority have been detected through indirect methods such as the transit method and the radial-velocity method. In the case of theTransit Method(aka. Transit Photometry), a planet is observed when crossing the path (i.e. transiting) in front of its parent star's...
The mass is a fundamental characteristic of an exoplanet. Scientists can learn a lot about how planets form around their stars by comparing how massive different exoplanets are. Two methods can provide us with information on the mass of exoplanets. One is the radial velocity method, used by se...
Astronomers who work on the complex modeling of the interiors of rocky planets make the simplifying assumption that the planet consists of two or three layers. This is not perfect, but it is a reasonable approximation and another good example of how science works. Often, the first step in und...
It was not an easy detection; never before had such a small planet in such a distant orbit been spotted using the radial velocity method. The research team analyzed 20 years' worth of observations, which were made by seven different instruments.Barnard's Star b lies about 0.4 astronomical ...

Aiming at the difficult detection precision test problem for a netted radar system,a method of calculating detection precision for netted radar system is proposed in this paper. 针对雷达组网系统探测精度的考核问题,提出了一种评估雷达组网系统探测精度的方法。 更多例句>> 4...
The standard deviation is indicated by the error bar. The figure shows that the liquid fraction for the upward and downward flows reduce with increasing gas superficial velocity. The observed trend could be as a result of an increase in gas production leading to a corresponding decrease in ...

You were instructed to keep this velocity, by a method that would guarantee it was kept. Therefore your tangential velocity is also r/t. You do not have an orbital velocity, since there is no such thing as an orbital velocity. Velocities do not curve. What you have is a sort of ...
