Sentences with phrase «induced by an orbiting planet»

From the ground, the researchers looked for Doppler shifts in the suspect stars» light spectra that would reveal a gravitational wobble induced by an orbiting planet.

Small shifts of the spectrum relative to the stable wavelength standard provided by the laser comb would yield a precision measurement of the wobble induced by an orbiting planet.

Not exact matches

Although hundreds of exoplanets had already been found orbiting sun - like stars throughout the Milky Way, they had been discovered by indirect means — astronomers had inferred the presence of a planet by observing the dimming effects or gravitational wobble an orbiting companion induces on its parent star.

Of the more than 300 other known exoplanets, all have been detected indirectly by their effects on their parent stars — either a wobble in induced by the object's orbit or a decrease in detected light from the star as the planet passes in front of it.

The changes in eccentricity of Earth's orbit are due to alterations in the gravitational tugs induced by other planets.
