Is there one method of detecting exoplanets that is more effective than the others? Or are they all equally effective? Are some methods better suited for different conditions?
The easiest way to detect exoplanets is by the transit method. This is when the exoplanet passes between the earth and the star its orbiting, causing the star to dim. This is the process of how most exoplanets have been discovered.
Before there was great technology to find these exoplanets, scientist used the pulsar method. This method is when a pulsar (which is a star) lets off radio waves. The exoplanets orbiting these pulsars are detected by the radio waves the pulsar lets off. This method was how the first two exoplanets were discovered.
Astronomers have learned that the parent star will wiggle more if there is a large exoplanet near by and learned that parent stars will most likely be brighter then the exoplanet.

DeleteYou mentioned that the two first discovered exoplanets took years to discover due to limited technology. What strategy was used to discover those?

DeleteWhat are the majority of exoplanets composed of?
ReplyDeleteMost exoplanets are kind of similar to earth. They are rockey and mostly composed of oxygen, iron, magnesium, and carbon.
DeleteWhat periods have astronomers used the Doppler Spectroscopy?
ReplyDeleteThe Doppler Spectroscopy was used to find about 30% of the exoplanets that have been found up to date. It was proposed in 1952
DeleteHow do astronomers use exoplanets to learn more about their parent star? Can an exoplanet be used to located other things in out solar system?
ReplyDeleteAstronomers have learned that the parent star will wiggle more if there is a large exoplanet near by and learned that parent stars will most likely be brighter then the exoplanet.
