Sentences with phrase «via radial velocity»

When the first exoplanet was identified via the radial velocity method, the Swiss team was able to detect a wobble in the star 51 Pegasi at a rate of 50 meters per second.

Artist's impression of 51 Pegasi b, discovered via radial velocity to be a hot, Jupiter - like planet around a Sun - like star.

[106] Theoretical studies on the detectability via radial velocity analysis have shown that a dedicated campaign of high - cadence observations with a 1 - meter class telescope can reliably detect a hypothetical planet of 1.8 M ⊕ in the habitable zone of B within three years.

[109] The observational thresholds for planet detection in the habitable zones via the radial velocity method are currently (2017) estimated to be about 50 M ⊕ for Alpha Centauri A, 8 M ⊕ for B, and 0.5 M ⊕ for Proxima.

Found via radial velocity variations, the planet's true mass could not be known with knowing whether its orbit around Star B is being viewed edge - on, face - on, or somewhere in between.

Not exact matches

Still, many of the nearby planets are detectable via three exoplanet hunting methods: planetary transits, high - contrast imaging, and stellar radial velocity measurements.

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).

The planet is confirmed via both the detection of the radial velocity orbit, and the Doppler tomographic detection of the shadow of the planet over two transits.

The planet is confirmed via both the detection of the radial velocity orbit, and the Doppler tomographic detection of the sha... ▽ More We present the discovery of a hot - Jupiter transiting the V = 9.23 mag main - sequence A-star KELT - 17 (BD +14 1881).

We detected the transit light - curve signature in the course of the TrES multi-site transiting planet survey, and confirmed the planetary nature of the companion via multicolor photometry and precise radial velocity measurements.

Most importantly, as Feng explained via an email exchange shared with Gizmodo, the research pushes the limits of the sorts of planets we can detect with the radial velocity method, boosting our prospects of discovering truly Earth - sized, rocky worlds in the future.
