The UMIST database for astrochemistry 2012
D. McElroy, C. Walsh, A. J. Markwick +3
We present the fifth release of the UMIST Database for Astrochemistry (UDfA). The new reaction network contains 6173 gas-phase reactions, involving 467 species, 47 of which are new…
Separated Structure Functions for Exclusive and Electroproduction at 5.5 GeV with CLAS
D. S. Carman, K. Park, B. A. Raue +1
We report measurements of the exclusive electroproduction of and final states from an unpolarized proton target using the CLAS detector at the Thomas Jefferson Nati…
The Solar Connection of Enhanced Heavy Ion Charge States in the Interplanetary Medium: Implications for the Flux-rope Structure of CMEs
N. Gopalswamy, P. MÄkelÄ, S. Akiyama +3
We investigated a set of 54 interplanetary coronal mass ejection (ICME) events whose solar sources are very close to the disk center (within 15 degrees from the central meridian).…
Stochastic coupling of solar photosphere and corona
Vadim M. Uritsky, Joseph M. Davila, Leon Ofman +1
The observed solar activity is believed to be driven by the dissipation of nonpotential magnetic energy injected into the corona by dynamic processes in the photosphere. The enormo…
Measurement of transparency ratios for protons from short-range correlated pairs
O. Hen, H. Hakobyan, R. Shneor +5
Nuclear transparency, Tp(A), is a measure of the average probability for a struck proton to escape the nucleus without significant re-interaction. Previously, nuclear transparencie…
Near Threshold Neutral Pion Electroproduction at High Momentum Transfers and Generalized Form Factors
P. Khetarpal, P. Stoler, I. G. Aznauryan +157
We report the measurement of near threshold neutral pion electroproduction cross sections and the extraction of the associated structure functions on the proton in the kinematic ra…
The Driver of Coronal Mass Ejections in the Low Corona: A Flux Rope
X. Cheng, J. Zhang, D. M. Ding +2
Recent Solar Dynamic Observatory observations reveal that coronal mass ejections (CMEs) consist of a multi-temperature structure: a hot flux rope and a cool leading front (LF). The…
Observations and models of slow solar wind with Mg9+ ions in quiescent streamers
Leon Ofman, Lucia Abbo, Silvio Giordano
Quiescent streamers are characterized by a peculiar UV signature as pointed out by the results from the observations of the Ultraviolet and Coronograph Spectrometer (UVCS) on board…
Multiwavelength study of a Solar Eruption from AR NOAA 11112: II. Large-Scale Coronal Wave and Loop Oscillation
Pankaj Kumar, K. -S. Cho, P. F. Chen +2
We analyse multiwavelength observations of an M2.9/1N flare that occurred in AR NOAA 11112 on 16 October 2010. AIA 211 Å EUV images reveal the presence of a faster coronal wave (de…
Multiwavelength study of a Solar Eruption from AR NOAA 11112 I. Flux Emergence, Sunspot Rotation and Triggering of a Solar Flare
Pankaj Kumar, Sung-Hong Park, K. -S. Cho +1
We analyse the multiwavelength observations of an M2.9/1N flare that occurred in the active region (AR) NOAA 11112 in the vicinity of a huge filament system on 16 October 2010. SDO…
Direct Measurement of the X-ray Time-Delay Transfer Function in Active Galactic Nuclei
E. Legg, L. Miller, T. J. Turner +3
The origin of the observed time lags, in nearby active galactic nuclei (AGN), between hard and soft X-ray photons is investigated using new XMM-Newton data for the narrow-line Seyf…
Magnetic Field Configuration Models and Reconstruction Methods for Interplanetary Coronal Mass Ejections
N. Al-Haddad, T. Nieves-Chinchilla, N. P. Savani +6
This study aims to provide a reference to different magnetic field models and reconstruction methods for interplanetary coronal mass ejections (ICMEs). In order to understand the d…
Persistent Doppler shift oscillations observed with HINODE/EIS in the solar corona: spectroscopic signatures of Alfvenic waves and recurring upflows
Hui Tian, Scott W. McIntosh, Tongjiang Wang +4
Using data obtained by the EUV Imaging Spectrometer (EIS) onboard Hinode, we have per- formed a survey of obvious and persistent (without significant damping) Doppler shift oscilla…
Rotational and Cyclical Variability in gamma Cassiopeiae. II. Fifteen Seasons
Gregory W. Henry, Myron A. Smith
The B0.5IVe star gam Cas is of great interest because it is the prototype of a small group of classical Be stars having hard X-ray emission of unknown origin. We discuss results fr…
Hot Gas, Cold Gas and Sub-Halos in a Lyman-alpha Blob at Redshift 2.38
Paul. J. Francis, Michael A. Dopita, James W. Colbert +5
We present integral field spectroscopy of a Lyman-alpha blob at redshift 2.38, with a spectral resolution three times better than previous published work. As with previous observat…
Comparative Modelling of the Spectra of Cool Giants
T. Lebzelter, U. Heiter, C. Abia +24
Our ability to extract information from the spectra of stars depends on reliable models of stellar atmospheres and appropriate techniques for spectral synthesis. Various model code…
