TL;DR: In this paper, the authors present near-UV transmission spectroscopy of the highly irradiated transiting exoplanet WASP-12b, obtained with the Cosmic Origins Spectrograph on the Hubble Space Telescope.

TL;DR: In this paper, the authors present a new non-detection limit of the nearby SN Ia 2011fe, obtained at a time that appears to be just 4-hr after the explosion, allowing them to directly constrain the initial primary radius (Rp ).

TL;DR: In this article, a new non-detection limit of the nearby SN Ia 2011fe, obtained what appears to be just 4 hours after the explosion, was presented, allowing us to directly constrain the initial primary radius, R_p Coupled with the nondetection of a quiescent X-ray counterpart and the inferred synthesized Ni mass, we show that R_ p 10,000 gm cm^{-3}, and that the effective temperature must be less than a few x 10^5 K.

TL;DR: In this article, the authors observed the distant but more extreme close-in hot Jupiter system, WASP-12, with the Hubble Space Telescope (HST) and revealed significantly enhanced absorption (greater than 3σ below the median) at ~200 individual wavelengths on each of two HST visits, using a strict criterion for velocity matching that excludes matches with velocity shifts exceeding ~20 km s−1.

TL;DR: In this article, the authors observed the extreme close-in hot Jupiter system WASP-12 with HST and revealed significantly enhanced absorption (greater than 3σigma below the median) at ~200 wavelengths on each of two HST visits; 65 of these wavelengths are consistent between the two visits, using a strict criterion for velocity matching which excludes matches with velocity shifts exceeding 20 km/s.
