Kepler-705
This is a list of exoplanets discovered in 2016. As of 2024, 2016 was the year with the most discoveries of exoplanets. For exoplanets detected only by radial velocity, the mass value is actually a lower limit. (See Minimum mass for more information) List Excluded objects and former candidate The majority of exoplanet discoveries in 2016 were from a paper by Morton ''et al.'' that statistically validated over 1,000 Kepler planets. This statistical validation did not involve mass measurements, and some transiting objects validated as planets were later shown (or even previously known) to be small stars. Such cases include Kepler-469 (KOI-126), Kepler-470 (KOI-129), Kepler-486 (KOI-189), Kepler-488 (KOI-194), Kepler-503 (KOI-242), Kepler-628 (KOI-631), Kepler-699 (KOI-846), Kepler-706 (KOI-855), Kepler-807 (KOI-1288), Kepler-840 (KOI-1416), and Kepler-854 (KOI-1450). In another two cases, Kepler-492 (KOI-205) and Kepler-494 (KOI-219), the companions are brown dwarfs with masses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minimum Mass
In astronomy, minimum mass is the lower-bound calculated mass of observed objects such as planets, stars, binary systems, nebulae, and black holes. Minimum mass is a widely cited statistic for extrasolar planets detected by the radial velocity method or Doppler spectroscopy, and is determined using the binary mass function. This method reveals planets by measuring changes in the movement of stars in the line-of-sight, so the real orbital inclinations and true masses of the planets are generally unknown. This is a result of sin ''i'' degeneracy. If inclination ''i'' can be determined, the true mass can be obtained from the calculated minimum mass using the following relationship: M_\text = \frac Exoplanets Orientation of the transit to Earth Most stars will not have their planets lined up and orientated so that they eclipse over the center of the star and give the viewer on earth a perfect transit. It is for this reason that when we often are only able to extrapolate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HATS-30b
HATS-3 is an F-type main-sequence star away. Its surface temperature is 6351 K. HATS-3 is relatively depleted in its concentration of heavy elements, with a metallicity Fe/H index of −0.157, but is slightly younger than the Sun at an age of 3.2 billion years. A multiplicity survey in 2016 detected a candidate stellar companion to HATS-3, 3.671 arc-seconds away. Planetary system In 2013, one planet, named HATS-3b, was discovered on a tight, nearly circular orbit. The planetary orbit of HATS-3b is likely aligned with the equatorial plane of the star, at a misalignment angle of 3°. The planetary equilibrium temperature is 1643 K.
