Not exact matches
The standard approach has been to take additional observations for each candidate to rule out possible false positive scenarios, or to detect the planet with a second technique.
NASA came under criticism in June when it announced that its space - based telescope Kepler had detected 706 potential new exoplanets, but only released data for 306 of the candidate planets.
A number of planet candidates are three to four times larger than Jupiter, which means that Kepler most likely detected double - star systems in which one star was passing in front of the other.
When it was first detected and reported last year in Astrophysical Journal, Gliese 581g appeared to be the perfect candidate for a true «Earth - like» planet.
Several Earth - like planets and super-Earths have been detected in the habitable zones of their host stars and more than 2300 planetary candidates have been announced.
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).
Transit signals detected in 2013 observations indicate that planetary candidate c could be an Earth - sized planet with a year lasting no more than 20.4 days, putting it slightly further out than Bb but still scorchingly close to the star (Demory et al, 2015; and Jacob Aron, New Scientist, March 27, 2015).
By comparing their distribution with that of the Kepler Objects of Interest detected during the first six quarters of operation of the spacecraft, we infer the false positive rate of Kepler and study its dependence on spectral type, candidate planet size, and orbital period.
We present here 275 planet candidates observed during Campaigns 0 - 10 of the K2 mission that are orbiting stars brighter than 13 mag (i... ▽ More Since 2014, NASA's K2 mission has observed large portions of the ecliptic plane in search of transiting planets and has detected hundreds of planet candidates.
We then compare the number of observed planet candidates to the number of stars around which such planets could have been detected in order to estimate the planet occurrence rate around cool stars.
There are 49 planet candidates around these stars, including 42 detected through transits and 7 revealed by precise Doppler measurements of the host stars.
Abstract: Since 2014, NASA's K2 mission has observed large portions of the ecliptic plane in search of transiting planets and has detected hundreds of planet candidates.
Abstract: We recently used near - infrared spectroscopy to improve the characterization of 76 low - mass stars around which K2 had detected 79 candidate transiting planets.
The study, which took five years, only looked for planets that orbited rather close to their parent stars (unless the planet is very large the signal from its gravitational hug is too slight to detect with today's technology) so this batch won't produce good candidates for worlds with liquid surface water that might be suited for life.
These results are based on the 1,235 planets (formally «planet candidates») from the Kepler mission that include a nearly complete set of detected planets as small as 2 Earth radii (Re).
K2 - 27b is a warm Neptune orbiting its host star in 6.77 days and has a... ▽ More We report on Doppler observations of three transiting planet candidates that were detected during Campaign 1 of the K2 mission.
Astronomers have detected more than 1,000 confirmed planets and almost 5,000 candidates beyond our solar system, with most of them found by NASA's Kepler Space Telescope.
Abstract: We report on Doppler observations of three transiting planet candidates that were detected during Campaign 1 of the K2 mission.
In particular, it was shown that less than half of the detected big transiting planet candidates are actually there.
The smallest planet orbits Kepler - 33, a star older and more massive than our Sun, Sol, which also had the most detected planet candidates at five (ranging in size from 1.5 to 5 times that of Earth) in uninhabitable, hot inner orbits closer to their star than even Mercury around our Sun (NASA Kepler news release; and JPL news release).
