Sentences with phrase «tight orbit with»

The high temperatures experienced by Kepler - 13Ab are a result of its tight orbit with its parent star, which has in turn led to the world becoming tidally locked with the stellar body.

Superflares - According to one recent hypothesis, unusually intense stellar flares from a sun - like («Sol - type») star could be caused by the interaction of the magnetic field of a giant planet in tight orbit with that star's own magnetic field.

Not exact matches

Instead, you're propelling it forward and back in a tight elliptical orbit, with a little jolt of the wrist for necessary lift.

But given that the era of discovering extrasolar planets is still in its infancy, with methods that more easily detect planets if they are massive and in tight orbits, how can we be certain that the exoplanets discovered so far are typical?

That parts - per - million sensitivity should allow Corot to detect the dips in a star's light caused by a transiting planet with a radius just twice that of Earth — and perhaps an even smaller one, provided its orbit is tighter than Mercury's, so that the planet completes three transits during the 150 - day viewing period.

Planets with extremely tight orbits offer scientists a wealth of data: For instance, each week Kepler 78b circles its star about 20 times, giving researchers numerous opportunities to observe its behavior.

However, other predictions, such as not expecting massive planets in tight orbits, is still largely contradictory to the hypothesis and greater testing with additional discoveries will be needed.

On October 16, 2012, a team of astronomers announced the discovery of a planet with around 1.13 + / - 0.09 Earth - masses in a very hot and tight, circular orbit around Alpha Centauri B, using the European Southern Observatory's the High Accuracy Radial velocity Planet Searcher (HARPS) instrument on the 3.6 - metre telescope at ESO's La Silla Observatory in Chile.

The main finding is that WASP - 18b, a highly irradiated hot Jupiter in a tight orbit around a hot F - type star, is «wrapped in a smothering stratosphere loaded with carbon monoxide and devoid of water».

By providing astrometry with a precision of the order of 10 microarcsecond and imaging with a resolution of 4 milliarcseconds, GRAVITY will be able to monitor stars with tighter orbits around Sgr ~ A * (within a few hundreds gravitational radii).

On June 16, 2008, a team of astronomers announced at the 2008 Extra Solar Super-Earths Workshop in France their discovery of a «super-Earth» class planet in a tight orbit around this star with with two other gas planets in outer orbits (ESO press release and Bouchy et al, 2009 — more details below).

On June 16, 2008, a team of astronomers announced at the 2008 Extra Solar Super-Earths Workshop in France their discovery of one «super-Earth» type planet in a tight orbit around this star with two other gas giant planets in outer orbits (ESO press release and Bouchy et al, 2009).

The orbit of an Earth - like planet (with liquid water) around this tight binary (Aab) would have to be centered around 1.3 AUs — between the orbital distances of Earth and Mars in the Solar System — with an orbital period between one and two Earth years.

The orbit of an Earth - like planet around the tight binary system that star Ba forms with its brown dwarf companion in the liquid water zone would have to be centered around 1.1 AU — a little farther than Earth's orbital distance around Sol — with an orbital period exceeding one Earth year.

Or we find a bunch of rocky planets — larger than Earth, but definitely rocky — gathered in tight formation around a star (with orbits that last 3.7 days!

On September 6, 2007, a team of astronomers (Michael Endl, William D. Cochran, Robert A. Wittenmyer, and Alan P. Boss) submitted a paper on the discovery of a Neptune - class planet (of at least 24.5 Earth - masses or 0.0771 Jupiter - masses) in a tight inner orbit (a = 0.0727 ± 0.0007 AUs) with a period less than 10.24 days, based on data from the HRS spectrograph on the Hobby - Eberly Telescope (Endl et al, 2008; and their web page on GJ 176 — more below).
