You mentioned in the presentation that some planets orbit opposite of the direction of the star. Is there any particular reason that might occur that we know of?
This was just discovered in the last six years and is still very unusual. The planets with this paradoxical orbit are usually giant planets. The reverse orbit is caused by the other planets gravitational pull on the exoplanet.
A star wobbles because of a planets gravitational pull. So when astronomers find a star that has a wobble they know there is a planet (exo planet) orbiting it and causing it to wobble. For example in our solar system our sun has a wobble in it due to Jupiter's gravity.
In your presentation, you said Radial Velocity was the second most common method to detect exoplanets. What is the first most common way?
ReplyDeleteThe most successful method used to detect exoplanets is the transit photometry method.
DeleteWhy is the Pulsar timing method the rarest method to use when detecting exoplanets?
ReplyDeleteTo use the Pulsar timing method astronomers have to detect Pulsars. Pulsars themselves are very rare as of right now.

DeleteHow are scientists able to detect these planets beyond our solar system?
ReplyDeleteThere are many different methods for detecting these planets. We listed and explained these methods on slide 6-11!

DeleteIf you could pick a method to detect exoplanets, which one would you choose and why?
ReplyDeleteI would pick the Pulsar timing method because it is very interesting how they use a neutron star to detect a planet from so far away!
DeleteIf you could name an exoplanet, what would you name it?
ReplyDeleteI would name it Plavchan because that is our teachers name.
DeleteHow many exoplanets have scientists actually confirmed? Are there any more than the ones you have presented ?
ReplyDeleteScientists have confirmed more than 1,000 exo planets. There are about 3,500 planets waiting to be confirmed.
DeleteMore than 1,900 confirmed**
DeleteHow/why do stars wobble and why is it important in relation to exoplanets?
ReplyDeleteA star wobbles because of a planets gravitational pull. So when astronomers find a star that has a wobble they know there is a planet (exo planet) orbiting it and causing it to wobble. For example in our solar system our sun has a wobble in it due to Jupiter's gravity.
