Four Giant Exoplanets of Star HR 8799 (Infographic) Unlike most exoplanet discoveries, the system of HR 8799 can be directly viewed by Earth-based telescopes. The enhanced carbon-to-oxygen ratio and depleted levels of C and O in planet c favor a history in which the planet formed through core accretion. The iron abundance was updated to 30+6−5% of solar value. The best accepted value for an age of HR 8799 is 30 million years, consistent with being a member of the Columba association co-moving group of stars. Planetary systems with the best-fit masses from evolutionary models would be stable if the outer three planets are in a 1:2:4 orbital resonance (similar to the Laplace resonance between Jupiter's inner three Galilean satellites: Io, Europa and Ganymede as well as three of the planets in the Gliese 876 system). Brown dwarfs would not be stable in such a configuration. This footage consists of 7 images of HR 8799 taken with the Keck Telescope over 7 years.

However, in 2010 a team from NASAs Jet Propulsion Laboratory demonstrated that a vortex coronagraph could enable small telescopes to directly image planets. [17] The system is more likely to be stable if the planets "e", "d" and "c" are in a 4:2:1 resonance, which would imply that the orbit of the planet d has an eccentricity exceeding 0.04 in order to match the observational constraints. Comparison with stars having similar motion through space gives an age in the range 30–160 million years. The first spectroscopic study of planet b (performed at near-infrared wavelengths) detected strong water absorption, which indicates a hydrogen-rich atmosphere. --Janke | Talk 22:25, 4 March 2017 (UTC) Thank you Janke. = 2.2 times farther from HR 8799 than from the Sun, meaning that corresponding planets in the solar and HR 8799 systems receive similar amounts of stellar radiation.[7]. Awesome! Compared to models of planetary atmospheres, this first spectrum of planet b is best matched by a model of enhanced metallicity (about 10 times the metallicity of the Sun), which may support the notion that this planet formed through core-accretion. [36] In 2011, three further exoplanets were rendered viewable in a NICMOS image taken in 1998, using advanced data processing. [11], In 2020, spectral analysis utilizing multiple data sources have detected an inconsistency in prior data and concluded the star carbon and oxygen abundances are the same or slightly higher than solar. Officially pronounced with a hard "J" Press J to jump to the feed. Given the star's position on the Hertzsprung–Russell diagram of luminosity versus temperature, it has an estimated age in the range of 30–1,128 million years. The star is also classified as a Lambda Boötis star, which means its surface layers are depleted in iron peak elements. The center black blob is a star well over 100 light years away named HR 8799 . The diameter of Pluto's orbit (≈ 80 AU) is shown for reference as a dot in the centre. Follow. [27], Moderate-resolution near-infrared spectroscopy, obtained with the Keck telescope, definitively detected carbon monoxide and water absorption lines in the atmosphere of planet c. The carbon-to-oxygen ratio, which is thought to be a good indicator of the formation history for giant planets, for planet c was measured to be slightly greater than that of the host star HR 8799. [3][4], Age determination of this star shows some variation based on the method used. These objects are near the upper mass limit for classification as planets; if they exceeded 13 Jupiter masses, they would be capable of deuterium fusion in their interiors and thus qualify as brown dwarfs under the definition of these terms used by the IAU's Working Group on Extrasolar Planets. The most distant worlds orbiting HR 8799 take hundreds of years to make a complete revolution.
