XO-6b is one of the puffiest planets ever discovered, with a maximum mass of 4.4 times of Jupiter. It is over twice as wide, making it one of the largest exoplanets ever found (see list of largest exoplanets ).

2024年10月24日 · XO-6 b is a gas giant exoplanet that orbits a F-type star. Its mass is 4.4 Jupiters, it takes 3.8 days to complete one orbit of its star, and is 0.0815 AU from its star. Its discovery was announced in 2016.

2016年12月8日 · Here, we report the discovery of the transiting hot Jupiter XO-6b, which orbits a bright, hot, and fast rotating star: V = 10.25, Teff = 6720 +/- 100 K, v sin i = 48 +/- 3 km/s. We detected the planet from its transits using the XO instruments and conducted a …

2017年2月3日 · We show that XO-6b is a transiting hot Jupiter on a prograde, misaligned orbit with a sky-projected obliquity λ = −20 7 ± 2 3. XO-6b orbits around a bright star (H = 9.27) and is relatively warm (K), thus it is well suited to atmospheric studies. We derive the stellar parameters through a spectral analysis and a minimization in stellar ...

2020年9月22日 · Abstract: From previous ground-based observations, the hot Jupiter exoplanet XO-6b was reported to exhibit apparently periodic transit timing variations (TTVs), with a semi-amplitude of 14 minutes and a period of about 450 days. These variations were interpreted as being due to a resonant perturbation between XO-6b and a hitherto unknown low ...

XO-1b to XO-5b1. A new version of XO was deployed in 2011 and 2012 and operated nominally from 2012 to 2014. In this paper, we report the discovery of XO-6b, a transiting hot Jupiter orbiting a bright and fast rotat-ing star. After its detection by the XO instruments, we conducted a follow-up campaign via photometry, radial

2019年11月16日 · Only a few exoplanets are known to orbit around fast rotating stars. One of them is XO-6b, which orbits an F5V-type star. Shortly after the discovery, we started multicolor photometric and radial-velocity follow-up observations of XO-6b, using the telescopes of Astronomical Institute of the Slovak Academy of Sciences.

Here, we report the discovery of XO-6b, a hot Jupiter orbiting a fast rotating and bright F5 star (Teff = 6605 K, Vsini = 45 km/s, V = 10.25). This transiting hot Jupiter system is one of the very few with a stellar rotation period smaller than the planet orbital period (Prot < 1.41 d, Porb = 3.77 d), and adds to the sample of hot Jupiters ...
