Commonly used methods of indirect planet detection?
The most common method use to detect planets involve measuring the change in light intensity of a star. By observing and measuring the light output of a star over a period of time, regular, periodic fluctuations in the intensity of the light output can indicate a planet orbiting the star. As the planet pass in front of the start, the measurable light is less.

Radial velocity - Just like the star pulls on the planet, so does the planet pulls on the star - but only a bit. By observing a star for a long period one can detect periodica…l movements caused by an orbiting planet. Transits - Sometimes a planet will pass in front of a star and hide a small portion of its light. By tracking a star's brightness, it is possible to detect a passage of a planet. Micro-lensing - General relativity has taught us that massive objects bend light. If one star with a planet passes in front of another star we can see a distortion of light which can tell us whether a planet is present or not. Direct observation - The most unlikely method, since extrasolar planets are hidden in their stars glare, but people are working on it.

No because microlensing requires the object being to be producing alight source and a plant doesn't. Even if a planet were reflectinglight it wouldn't be enough to be seen.
The easiest is to search for the drops in the measured brightness of their stars when some of the planets transit across them. Not all planets do this however. This will tell …you the planet's radius and its orbital period. This is called "the transit method" or "transit photometry" Another popular way is to detect the "wobble" of the star as the planet gravitationally tugs on it while orbiting around it. Measuring this will give you the minimum mass of the planet and its orbital period. This wobbling is very hard to detect, so it must be done indirectly, by watching the light from the star shifted by the Doppler effect. This is called "Doppler spectroscopy" or "radial velocity method." If you can detect a planet using both of these methods, then the mass of the planet is no longer a minimum mass, but you can determine the real mass, which you can combine with the radius to get a density which will tell you something about what kind of planet it is (a gas giant, or a solid terrestrial planet?). Another way is to directly observe the star wobbling around. This is hard to do but is feasible for some of the closer stars. This is called "astrometry." A more exotic way to do so is by waiting for a planetary system to pass in front of a background star. The foreground star's gravity will act as a magnifying glass, amplifying the brightness of the background star. The presence of a planet around the foreground star can, for some cases, cause further magnification or distortion to the light of the background star. This is called "gravitational microlensing."
Indirect measurement is a technique that uses proportions to find ameasurement when direct measurement is not possible.

"Give" and "tell" frequently have indirect objects: "He gave me five dollars." "I tell you the truth." Indirect objects are also supported by "lend", "throw", "save", …"leave": "Friends, Romans, countrymen, lend me your ears." "I threw him the ball." "I saved you a slice of pie." "He left me nothing."

Metal is generally recycled through the process of melting down the scraps of metal (making sure they're all the same type of metal) and then forming the melted metal into a n…ew form or product.
Cancer screening is done by several different methods depending on the type of cancer. It can be a blood test, a test of fluids from a growth or a scan.
