The recent transit observation of HD 209458 ban extrasolar planet orbiting a Sun-like star¨ con—rmed that it is a gas giant and determined that its orbital inclination is 85i. This inclination makes possible investigations of the planet atmosphere. In this paper we discuss the planet transmission spectra during a transit. The basic tenet of the method is that the planet atmosphere absorption features will be superimposed on the stellar —ux as the stellar —ux passes through the planet atmosphere… CONTINUE READING
