WASP-8 b
WASP-8 b is an extrasolar planet in the constellation of Sculptor. WASP-8 b is a gas giant exoplanet which was discovered on 1st April 2008 by Dr. Don Pollacco of Queen's University Belfast, Northern Ireland. This system is located 89 parsecs away, 293 light-years, which is closer than most Hot Jupiters.
Calculation of the radius
The coordinates of this exoplanet are RA 23h59m36.21s and Dec -35d01m52.81s, in the sexagesimal system.
Light curve calculation results:
Calculation of the Radius. We are going to use the units Jupiter Radius (R Jup), because it is a Hot Jupiter exoplanet so that, it is better to compare its radius to Jupiter.
As we have worked on base 1, now we have to multiply the result by a hundred. So then, the result is that WASP-8 b has a radius of 1,196 R Jup.
Now, searching weather the data is the same as the scientific articles at Scholar Google, we obtain that this data, approximately, corresponds with V. Bourrier et al. Article Number A33 in which it is said: "WASP-8b is a Jupiter-size planet (1.04 RJup; Queloz et al. 2010)". The small difference between our result and this value is probably due to the approximations made during the calculation.
Searching this data at Exoplanet Data Archive NASA-CALTECH we found that this value is of 1.13±0.05 Jupiter Radius.
Calculation of the mass
The calculation of the mass can be made from the calculation of the slope of the linear regression graphic of Terran worlds.
For the calculation of the mass, it has been used our own radius data obtained previously.
We obtain that the result is that WASP-8 b has a mass of 1,52 M Jup.
Searching weather the data is the same as the scientific articles at Scholar Google, we obtain that this data, approximately, corresponds with Patricio Cubillos et al. Article in which it is said: "WASP-8b has 2.18 times Jupiter's mass and (...).".
The difference between these values may be due to the approximations made during calculation: conversion factors, the radius data used, square roots approximations...
