Ultraviolet C II and Si III Transit Spectroscopy and Modeling of the Evaporating Atmosphere of GJ436b
R. O. Parke Loyd, T. T. Koskinen, Kevin France +2
Hydrogen gas evaporating from the atmosphere of the hot-Neptune GJ436b absorbs over 50% of the stellar Ly emission during transit. Given the planet's atmospheric composition and…
Velocity Segregation and Systematic Biases In Velocity Dispersion Estimates With the SPT-GMOS Spectroscopic Survey
Matthew. B. Bayliss, Kyle Zengo, Jonathan Ruel +15
The velocity distribution of galaxies in clusters is not universal; rather, galaxies are segregated according to their spectral type and relative luminosity. We examine the velocit…
Detection of thermal radio emission from a single coronal giant
Eamon O'Gorman, Graham M. Harper, Wouter Vlemmings
We report the detection of thermal continuum radio emission from the K0 III coronal giant Pollux ( Gem) with the Karl G. Jansky Very Large Array (VLA). The star was detected at…
Analytic solution of an oscillatory migratory alpha^2 stellar dynamo
Axel Brandenburg
Analytic solutions of the mean-field induction equation predict a nonoscillatory dynamo for homogeneous helical turbulence or constant alpha effect in unbounded or periodic domains…
The Puzzling Detection of X-rays From Pluto by Chandra
C. M. Lisse, R. L. McNutt, S. J. Wolk +17
Using Chandra ACIS-S, we have obtained imaging Xray spectrophotometry of the Pluto system in support of the New Horizons flyby on 14 July 2015. 174 ksec of observations were obtain…
Improved Measurement of the Spectral Index of the Diffuse Radio Background Between 90 and 190 MHz
Thomas. J. Mozdzen, Judd. D. Bowman, Raul. A. Monsalve +1
We report absolutely calibrated measurements of diffuse radio emission between 90 and 190 MHz from the Experiment to Detect the Global EoR Signature (EDGES). EDGES employs a wide b…
