HAT-P-26 is a K-type main-sequence star located about 466 light-years (143 parsecs) away in the constellation of Virgo. A survey in 2015 did not find any stellar companions in orbit around it, [4] although a red dwarf companion with a temperature 4000+100. −350 K …

2024年10月25日 · HAT-P-26 b is a Neptune-like exoplanet that orbits a K-type star. Its mass is 22.2481 Earths, it takes 4.2 days to complete one orbit of its star, and is 0.0479 AU from its star. Its discovery was announced in 2010.

2017年5月12日 · Using data from the Hubble and Spitzer Space Telescopes from 0.5 to 5 micrometers, we conducted a detailed atmospheric study of the transiting Neptune-mass exoplanet HAT-P-26b. We detected prominent H 2 O absorption bands with a maximum base-to-peak amplitude of 525 parts per million in the transmission spectrum.

detailed atmospheric study of the transiting Neptune-mass exoplanet HAT-P-26b. We detected prominent H 2O absorption bands with a maximum base-to-peak amplitude of 525 parts per million in the transmission spectrum. Using the water abundance as a proxy for metallicity, we measured HAT-P-26b’s atmospheric heavy element content (4:8þ21:5 4:0 ...

2011年1月31日 · HAT-P-26b is the fourth Neptune-mass transiting planet discovered to date. It has a mass that is comparable to those of Neptune and Uranus, and slightly smaller than those of the other transiting Super-Neptunes, but a radius that is ∼65% larger than those of Neptune and Uranus, and also larger than those of the other transiting Super-Neptunes.
