Carboniferous of Eastern Kentucky - Stops 4-6.
This guidebook was produced for participants of the Sixth Gondwana Symposium held at the Institute of Polar Studies in August 1985. The trip traverses the highly scenic Appalachian Plateau. Enroute to eastern Kentucky, nonmarine sandstone, mudstone, coal, and limestone of the Upper Carboniferous to Permian (?) Dunkard Group, and Upper Carboniferous Monongahela and Conemaugh Formations will be examined in southern Ohio and western West Virginia. In eastern Kentucky, examination of the rocks will proceed up through the sequence starting with the Lower Carboniferous Berea Sandstone, a shallow marine deposit with abundant sedimentary structures; followed by the Borden Formation, which represents a prograding delta with shelf to basin facies including turbidites and abundant sedimentary structures; followed by the Borden Formation, which represents a prograding delta with shelf to basin facies including turbidites and abundant sedimentary structures, trace, and invertebrate fossils; the Slade Formation, a shallow carbonate sequence with paleokarst and paleosol features, and ending with the Upper Carboniferous Breathitt Formation, a marine to nonmarine sandstone, mudstone, and coal unit with famous coal ball localities

Detection of a Thermal Spectral Component in the Prompt Emission of GRB 100724B
Observations of GRB 100724B with the Fermi Gamma-Ray Burst Monitor (GBM) find
that the spectrum is dominated by the typical Band functional form, which is
usually taken to represent a non-thermal emission component, but also includes
a statistically highly significant thermal spectral contribution. The
simultaneous observation of the thermal and non-thermal components allows us to
confidently identify the two emission components. The fact that these seem to
vary independently favors the idea that the thermal component is of
photospheric origin while the dominant non-thermal emission occurs at larger
radii. Our results imply either a very high efficiency for the non-thermal
process, or a very small size of the region at the base of the flow, both quite
challenging for the standard fireball model. These problems are resolved if the
jet is initially highly magnetized and has a substantial Poynting flux.Comment: 6 pages, 3 figures, 1 table, Accepted for publication in the

Hubble Space Telescope search for the transit of the Earth-mass exoplanet α Centauri Bb
Results from exoplanet surveys indicate that small planets (super-Earth size and below) are abundant in our Galaxy. However, little is known about their interiors and atmospheres. There is therefore a need to find small planets transiting bright stars, which would enable a detailed characterization of this population of objects. We present the results of a search for the transit of the Earth-mass exoplanet α Centauri Bb with the Hubble Space Telescope (HST). We observed α Centauri B twice in 2013 and 2014 for a total of 40h. We achieve a precision of 115ppm per 6-s exposure time in a highly saturated regime, which is found to be consistent across HST orbits. We rule out the transiting nature of α Centauri Bb with the orbital parameters published in the literature at 96.6 per cent confidence. We find in our data a single transit-like event that could be associated with another Earth-sized planet in the system, on a longer period orbit. Our programme demonstrates the ability of HST to obtain consistent, high-precision photometry of saturated stars over 26h of continuous observation
