WASP-1b is an extrasolar planet orbiting the star WASP-1 located 1,300 light-years away in the constellation Andromeda. The planet's mass and radius indicate that it is a gas giant with a similar bulk composition to Jupiter.

2024年10月24日 · WASP-1 b is a gas giant exoplanet that orbits a F-type star. Its mass is 0.854 Jupiters, it takes 2.5 days to complete one orbit of its star, and is 0.03889 AU from its star. Its discovery was announced in 2007.

wasp-1b是一刻環繞著恆星wasp-1的太陽系外行星，距離地球一千的光年，大小跟木星差不多，但是和離母恆星的距離很近，因此被歸類於熱木星。 木星 和WASP-1b的大小比較：

The orbit of WASP-1b is inclined to rotational axis of the star by 79.0 +4.3 −4.5 degrees, making it a nearly "polar" orbit. [7] Two searches for additional planets using transit-timing variations have yielded negative results. [8] [9]

2006年9月25日 · Using the newly-commissioned radial-velocity spectrograph SOPHIE at the Observatoire de Haute-Provence, we found that both objects exhibit reflex orbital radial-velocity variations with amplitudes characteristic of planetary-mass companions and in-phase with the photometric orbits.

WASP-1b and WASP-2b have orbital periods of 2.52 and 2.15 d, respectively. Given mass estimates for their F7V and K1V primaries, we derive planet masses 0.80–0.98 and 0.81–0.95 times that of Jupiter, respectively. WASP-1b appears to have an inflated radius of at least 1.33 R Jup, whereas WASP-2b has a radius in the range 0.65–1.26 R Jup.

Abstract: We report on photometric follow-up of the recently discovered transiting planet WASP-1b. We observed two transits with the Wise Observatory 1-m telescope, and used a variant of the Eclipsing Binary Orbit Program (ebop) code together with the Sys-Rem detrending approach to …

2006年10月19日 · We present precise z-band photometric time series spanning times of transit of the two exoplanets recently discovered by the SuperWASP collaboration. We find planetary radii of 1.44 +/- 0.08 R_J and 1.04 +/- 0.06 R_J for WASP-1b and WASP-2b, respectively.
