Exoplanet Definition and 70 Threads

Exoplanet discoveries continue to be made using various sensitive techniques. Since there is no evidence to the contrary none of them are thought to harbor life forms. Here is a new set of maps showing where the exoplanets are located in both the Northern and Southern Hemispheres...

Is it possible to detect exoplanets with amateur telescopes? If so what size would be needed. I have seen some amateur protoplanetary disks pictures and would one be able to tell if an exoplanet existed in it as I carved out the material for planet formation? Is it possible for us with current...

So I've read that super Earth's masses 2-10 can be habitable hold thick atmosphere and generate plate tectonics. So I am wondering the absolute minimum mass an exoplanet or moon can be to stay habitable in the liquid H2O zone? I guess these would be called subEarth's.

I'm amazed by this illustration :eek: I've known that exoplanet discovery had come a long way in recent years but to see it like this is astonishing. I'm curious, what does the near future hold for this field?

Well, I just made my first light curve of a transiting exoplanet, TRES-3B, the graph is here. It's my first time ever doing any photometry, but seeing as how the light curve matches the expected transit pretty much spot on it looks like I was successful. It's got me wanting to get more or...

Noob here, be gentle… I am of the understanding that the solar system formed by means of an accretion disk that made its plane normal to the sun rotation. I suppose that the Galactic plane formed by the same basic gravitational and centripetal means. Question: Does our Solar System’s...

Kepler22b--first exoplanet found in hab-zone of sun-like star http://science.nasa.gov/science-news/science-at-nasa/2011/05dec_firstplanet/ NASA newsletter ==quote== Kepler Confirms First Planet in Habitable Zone of Sun-like Star Dec 5, 2011: NASA's Kepler mission has confirmed its first...

What do you think is the best type to find planets in the habitabel zone? What do you think of the suggetsion of white dwarfs? http://news.softpedia.com/news/White-Dwarfs-Are-Newest-Targets-for-Exoplanet-Research-192407.shtml any better suggestions?

http://www.cnn.com/2011/US/01/10/nasa.planet.discovery/index.html?hpt=C1 This is a portion of the article, but it's quite optimistic. I hope that I'm not posting old news, and if I am please just delete this mentors. If not, I'm impressed, and this new era of finding exoplanets... what are...

Recently I been reading about exoplanets on wikipedia when I came across a line that caught my idea: So I started wondering exactly what did Wikipedia mean by "based on the intensity of light" and later on by "temperature measure by observing the variation in infrared radiation". I mean...

http://arxiv.org/abs/1006.2799 "On 15 June 2010 the Kepler Mission released data on all but 400 of the ~156,000 planetary target stars to the public. At the time of this publication, 706 targets from this first data set have viable exoplanet candidates with sizes as small as that of the Earth...

The German magazine Bild has a story that a team of astronomers have actually taken IR pictures of an exoplanet system around HR 8799, about 130 light years away. There are three planets, all larger than Jupiter, visible as three specks in the pictures. In addition, a team from the University of...

Hey all, Can anyone suggest any good websites or books that explain the hunt for and quantification of results about exoplanets and their orbits. Regards

Hi everyone. I am trying to find out which is the first comfirmed discovery of an exoplanet. When I look on the web, I find some sources telling me it was the one found around peg51 by Michel Mayor and team in 1995, but others saying it was the one found around pulsar PSR B1257+12 in 1992...

Hi there, Im wondering if it is possible to observe a known star that is known to have a Jupiter planet orbiting it, and analyse its light intensity to search for the planet with a Celestron C11 XLT and a CCD? Examining its spectra with some computer software. Its a thought for my final...

Hey guys, i made a thread a couple of weeks ago about how to derive equations for exoplanet data, and so far i´ve managed to derive an equation for the radial velocity as: V_{rad}=K[cos(\theta + \omega) + ecos(\theta + \omega) Which I'm guessing would be the function to be plotting against...

Hello Everyone I am currently researching a paper on the history of exoplanet hunting and I have reached an impass. I have heard a theory about how massive planets migrate towards their parent star by interacting with other massive planets, but ihave been unable to find the original journal...

I've been googling like crazy the past few hours trying to find something i can use :) I find a lot of general explenations, but I'm having a hard time finding a concrete model to what is used to get the final values that seem to be extracted from the data gained from doppler/radial velocity...

Questions in the title. Any help is appreciated :)
