You mentioned that planets orbit burned-out remnants of some stars, would that not cause the planets to collapse in on the stars that have been burned out because gravity would pull on the planet more strongly as the star dies out?
How would you have felt if you were Dr. Wolszczan? Do you think that there was a lot of pressure put on him in hopes that there was life on this exoplanet?
If I Were Dr. Wolszczan I would have been very proud of my discovery. I do believe he had a lot of pressure but not in the hopes that there was life on the exoplanet. I believe he probably faced more pressure to find more exoplanets.
The gravitational pull distorts the protoplanetary disks, so when there are two or more it causes it to pull causing there to be a disk of gas. The astronomers can then see the "gap" in the disk.
Because astronomers are still looking for planets that could sustain life. If something does happen and we can no longer live on Earth we would need to inhabit another planet
In your presentation you mention types of exoplanets. You state that they range from lava planets to water worlds and super-Earths. What does that mean? And are there any other types that you did not mention in your presentation?
With lava planets the surface is mostly covered with molten lava, water worlds are mostly covered with water, and super earths are larger than earth but similar qualities such as land and water masses. And yes there are types of planets that we did not name and I would imagine there would also be different types that we have yet to identify also.
In your presentation you talk about Protplanetary disks, what are they?
ReplyDeleteBasically just a ring of gas and dust that forms around a star that has recently formed.

ReplyDeleteHow do planets make their stars appear to wobble on the celestial sphere in the Astrometric method?
ReplyDeletePlanets have their own gravitational pull, so when they are around the sun their gravity kind of pulls on the sun.

ReplyDeleteYes the gravity does increase, but not to the amount that would be required to collapse it.
Deletehow many exoplanets have scientists confirmed?
ReplyDeleteAround 2,000 exoplanets.

DeleteYou mention if one or two planets orbit in a protplanetary disk it will affect the disk of gas and dust. But how does this detect the exoplanets?

ReplyDeleteWhy do you think it is important for scientists to continue to look for exoplanets?
