Sentences with phrase «giant exoplanets»
The phrase "giant exoplanets" refers to very large planets that orbit stars outside of our solar system. They are similar to the planets in our own solar system, like Jupiter and Saturn, but are located in different star systems far away from us. Full definition

SPHERE's primary task is to discover and study giant exoplanets orbiting nearby stars using direct imaging.
The best planet - imaging project on Earth is now at ESO's Very Large Telescope (VLT) in the high desert of northern Chile, where an instrument called SPHERE uses adaptive optics and coronagraphs to snap near - infrared and visible - light pictures of bright, young, giant exoplanets glowing red - hot from their recent formation.

«By showing astronomers where future missions such as NASA's James Webb Space Telescope have their best chance to find giant exoplanets, this research paves the way to future discoveries,» said chief scientist of NASA's Exoplanet Exploration Program Office and study co-author Karl Stapelfeldt of JPL.
SPHERE opens new horizons in the study of young brown dwarfs and giant exoplanets thanks to high - contrast imaging capabilities at optical and near - infrared wavelengths, as well as high signal - to - noise spectroscopy in the near - infrared from low (R ~ 30 - 50) to medium resolutions (R ~ 350).
So far the direct detection has only been able to show giant exoplanets, several times larger than Jupiter and orbiting at great distances from their stars.
Again the difficulty lies in detecting small exoplanets at far orbits, since giant exoplanets and close orbits exert much larger gravitational pulls over the star and create easily visible oscillations.
An international team1 led by Alexandre Santerne from Instituto de Astrofísica e Ciências do Espaço (IA2), made a 5 - year radial velocity3 campaign of Kepler's giant exoplanet candidates, using the SOPHIE4 spectrograph (Observatory of Haute - Provence, France), and found that 52,3 % were actually eclipsing binaries5, while 2,3 % were brown dwarfs6.
So, if other star systems contain gas giant exoplanets, it stands to reason that they would have the same effect on bodies orbiting close to their star.
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.
Constraints on the magnetic field strength of HAT - P - 7 b and other hot giant exoplanets.
So, based on our results we would expect that most giant exoplanets will have zonal circulation; we should expect that their atmospheres are not homogeneous, structureless, but in fact should display large brightness variations in the infrared.

When researchers observed star systems containing debris disks with giant exoplanets in distant orbits, they noted that the star systems had similar dual dust disks analogous to the Solar System's two zones — the asteroid belt (between Mars and Jupiter) and the Kuiper Belt (beyond the orbit of Neptune).
It will also be possible to study details of exotic objects in our Solar System, such as volcanoes on Io, and the atmospheres of giant exoplanets.
Nicolas Cowan, an astronomer at McGill University who has used Spitzer data to create thermal maps of gas - giant exoplanets, is not sure the aging telescope is up to the task of investigating smaller worlds.

Perhaps there are temperate, habitable moons orbiting some giant exoplanets.
There's also evidence to suggest that some giant exoplanets have magnetospheres, but we have yet to see conclusive proof.
Such an arrangement can only be explained, they say, by a giant exoplanet (just left of the star)-- which ALMA can't see — sweeping up all the material close to the star but pushing dust farther out still.
