HD 95086 b's brightness at 3.8 μm when combined with sensitive upper limits on its brightness at shorter wavelengths [12] is consistent with trends seen for other young, directly imaged planets like those around HR 8799. In particular, the lower limit of its 1.65–3.8 μm color of 3.1 magnitudes excludes background stars and most brown dwarfs.
The host star of HD 63433 c is HD 63433, a G-type main-sequence star that is located 73 light-years from Earth in the constellation Gemini. [ 4 ] [ note 5 ] The properties of this star, such as its radius (0.912 R ☉ ) and its mass (0.99 M ☉ ) are very similar to those of the Sun , which makes it classified as a Solar analog . [ 4 ]
HD 100546, also known as KR Muscae, is a pre-main sequence star of spectral type B8 to A0 located 353 light-years (108 parsecs) from Earth in the southern constellation of Musca. [4] The star is surrounded by a circumstellar disk from a distance of 0.2 to 4 AU, and again from 13 AU out to a few hundred AU, with evidence for a protoplanet ...
NASA Exoplanet Exploration Program "travel poster" for HD 40307 g. HD 40307 g is an exoplanet candidate suspected to be orbiting in the habitable zone of HD 40307.It is located 42 light-years away in the direction of the southern constellation Pictor.
HD 222925 is a horizontal branch star about 1,470 light years away in the southern constellation Tucana. It is magnitude 9, far below naked-eye visibility. It is an Ap star, a type of chemically peculiar star with an over-abundance of certain metals in its spectrum. HD 222925 has been referred to as the 'gold standard star' by the media. [8]
HD 189733 b is an exoplanet in the constellation of Vulpecula approximately 64.5 light-years (19.8 parsecs) away [7] from the Solar System. Astronomers in France discovered the planet orbiting the star HD 189733 on October 5, 2005, by observing its transit across the star's face. [ 1 ]
