Sentences with phrase «using radial velocity method»

HARPS has been enormously successful at detecting exoplanets using the radial velocity method, or measuring the gravitational tugs on stars by their planets by watching the stars» spectral lines «wobble» back and forth due to the Doppler effect.

[94] Proxima Centauri b was found using the radial velocity method, where periodic Doppler shifts of spectral lines of the host star suggest an orbiting object.

Additional simulation work presented in the paper also indicates that long - term telescopic observations may detect wobbles from such planets using the radial velocity method.

The planet was found using the radial velocity method: Telescopes scrutinize a star's light to see if its frequency is periodically stretched and squeezed by the Doppler effect as the star is tugged, first away and then toward us, by an orbiting planet.

HARPS - North detects planets using the radial velocity method, which allows astronomers to measure a planet's mass.

[4] Mass estimates for planets observed using the radial velocity method are lower estimates: if the planet's orbit is highly inclined it could have a higher mass and create the same observed effects.

Not exact matches

[2] The team looked at radial velocity data of Gliese 667C, a method often used to hunt for exoplanets.

Planet «b» - In 1996, a team of astronomers (including Eric Williams, Heather M. Hauser, and Phil Shirts) led by Geoffrey W. Marcy and R. Paul Butler announced the discovery of a Jupiter - class planet around Upsilon Andromedae (ups And) A using highly sensitive radial - velocity methods (Butler and Marcy, 1997.

The method used to detect carbon monoxide utilized the radial velocity (RV) technique — a technique commonly used in the visible region of the spectrum, to which our eyes are sensitive — for discovering non-transiting exoplanets.

Using the ten - meter Keck I telescope fitted with the HIRES instrument, the team employed the radial velocity method to measure how much an orbiting planet causes its star to wobble, to determine the planet's mass.

Recent simulations suggest that an Earth - life planet could have formed within the habitable zone around Alpha Centauri B, which can be detected using the radial - velocity «wobble» method (more).

On March 25, 2015, a team of astronomers using the Hubble Space Telescope revealed observations which indicate via the transit method that Alpha Centauri B may have a second planet «c» in a hot inner orbit, just outside planet candidate «b.» After observing Alpha Centauri B in 2013 and 2014 for a total of 40 hours, the team failed to detect any transits involving planet b (previously detected using the radial velocity variations method and recently determined not to be observed edge - on in a transit orbit around Star B).

As a subgiant star subject to pulsations which affect careful measurements of variations in radial velocity caused by the gravitational pull of substellar companions, astronomers would find it very difficult to detect any Earth - type planet around Beta Hydri using present methods.

Several established planet - hunting teams have used various radial velocity or star transit methods in their searches around these two bright stars.

In 1996, a team of astronomers (including Geoffrey W. Marcy and R. Paul Butler) announced the discovery of a Jupiter - class planet around 70 Virginis using highly sensitive radial - velocity methods (Marcy and Butler, 1996).

In 1996, a team of astronomers (including Eric Williams, Heather M. Hauser, and Phil Shirts) led by Geoffrey W. Marcy and R. Paul Butler announced the discovery of a Jupiter - class planet around Star A using highly sensitive radial - velocity methods (Butler et al, 1997).

As a subgiant star subject to pulsations which affect careful measurements of radial velocity, astronomers would find it very difficult to detect any Earth - type planet arond this star using present methods.

(Many exoplanets have also been discovered using another technique called the radial velocity method, which looks for the gravitational influence of a planet on its star.)

In 2012, astronomers announced they'd found evidence for five planets between two and seven times the mass of the Earth, using the so - called radial velocity or «wobble» method, which measures the gravitational tug a planet exerts on its star.

Kepler 10b was detected using the transit method from more than eight months of data collected by the spacecraft between May 2009 and early January 2010 and confirmed by radial velocity measurements, and there evidence for another planet (KOI 72.02) in an outer orbit with a period around 45.3 days (Kepler news release; images, animations, and discovery page; and Batalha et al, 2011).

In June 2003, a team of astronomers (including Dominique Naef, Francisco Pepe, Michel Mayor, Nuno C. Santos, Didier Queloz, and Stephane Udry) announced the discovery of a Jupiter - class planet around HR 111232 using radial - velocity methods (Observatoire de Genève page on HD 111232).
