Answer 2

Answer #2

Methods used by astronomers to detect planets around the stars are

i) Radial Velocity

ii) Direct Imaging

iii)Gravitational Lensing

iv) Transit method

v) Orbital Brightness

-------------------------------------------------------------------------

Majority of planets detected so far are done by transit method

Amount of light dimmed by the planet when it is passing between star and us is measured

---------------------------------------------------------------------------------------------------------

If they can find time taken for planet to revolve around the star. Using Keplers 3rd law they can find the size of the planet. ( Radial velocity method is used to find out time period of the planet)

In recent years, scientists have discovered hundreds of planets orbiting other stars. Some of these planets are in orbits that are similar to that of earth, which orbits the sun (Msun = 1.99 × 1030 kg) at a distance of 1.50 × 1011 m, called 1 astronomical unit (1 au). Others have extreme orbits that are much different from anything in our solar system. The following problem relates to one of these planets that follows circular orbit around its star....

What did Paul Ehrlich achieve with his discovery of 606 that was new to the field of microbe hunting? What was the unforeseen aspect of a “magic bullet”? From the time that Leeuwnhoek first saw microbes to the time Ehrlich discovered the cure for a disease caused by a microbe, information was steadily gained. Summarize what the microbe hunters had discovered. How did the microbe hunters use information from former and fellow scientists to help in their individual searches? Although...

The discovery of pulsars –rotating neutron stars that generate regular pulses of radiation at their spin rate- was fortuitous. A group of astrophysicists from Cambridge University lead by Anthony Hewish was looking for quasars (these are extremely bright, compact and remote objects that emit up to a thousand times as much light as our entire galaxy). For that purpose the research group designed a radio-telescope that was built on the flat fields surrounding Cambridge in central England. This telescope did...
