As always with brown dwarfs, the results are much more far - reaching than people often realize: brown dwarfs are excellent proxies
for giant exoplanets: often what we can not learn from giant exoplanets we learn from brown dwarfs.
Young stars that are from a few million to one billion years old and appear to have a disk of dust and debris orbiting them may be the best place to look
for giant exoplanets.
The paper suggests that when astronomers are looking
for these giant exoplanets, they should concentrate on looking at young star systems that have debris disks around them.

giants orbiting distant stars and, one day, rocky
exoplanets similar to our own.
Astronomers have
for the first time detected ingredients in the atmosphere of a super-Earth, an exotic type of
exoplanet of which there is no parallel in our solar system: It's larger than our home but not as large as a gas

I'm still holding out
for the news that reads: «Second Earth Found» -[this
exoplanet] will have all the right ingredients: orbit its star inside the habitable zone, spectroscopic analysis will reveal a nitrogen - rich atmosphere, evidence of water, roughly the same mass as our planet and it will belong in a system with a couple of gas
giants shepherding the outer system.
Before Kepler, plenty of Jupiter - sized worlds could be seen, but with its precision eye
for spotting the tiniest of fluctuations of star brightness (as a small
exoplanet passes between Kepler and the star), the space telescope has found that smaller
exoplanets outnumber the larger gas
giants.
We underscore the significance of long - term ground - based monitoring of hot stars and space - based targeting of hot stars with the Transiting
Exoplanet Survey Satellite (TESS) to search
for inflated
giants in longer - period orbits.
The project, led by principal investigator George Ricker, a senior research scientist at the MIT Kavli Institute
for Astrophysics and Space Research (MKI) will use an array of wide - field cameras to perform an all - sky survey to discover transiting
exoplanets, ranging from Earth - sized planets to gas
giants, in orbit around the brightest stars in the sun's neighborhood.
