Weather on an Exo-Neptune

Image at 7 mm wavelength of the dusty disk around the star HD 169142 obtained with the Very Large Array (VLA) at 7 mm wavelength. The positions of the protoplanet candidates are marked with plus signs (+) (Osorio et al. 2014, ApJ, 791, L36). The insert in the upper right corner shows, at the same scale, the bright infrared source in the inner disk cavity, as observed with the Very Large Telescope (VLT) at 3.8 micron wavelength (Reggiani et al. 2014, ApJ, 792, L23).

Clear skies and high humidity on an Exo-Neptune

A team of astronomers spanning three continents and including a member of the SPF group has observed system the atmosphere of the wholesale jerseys extrasolar planet HAT-P-11b using data from three space telescopes – Hubble, Kepler and Spitzer. HAT-P-11b is a relatively small object, roughly the size of Neptune, however it is much hotter at about 600 degrees C. The observations revealed an unambiguous signature Strips of water vapor in the atmosphere. This (Berks) came as a surprise because previous studies of similar exoplanets did not lead to detections of any of the atmospheric components. One possible explanation of this is that most such objects are covered with thick layers of clouds, apparently with the exception of HAT-P-11b.
