2011/10/14
Charged-current neutrino-nucleus cross sections for 54,56Fe and 58,60Ni are calculated and compared using frameworks based on relativistic and Skyrme energy density functionals, and the shell model. T...

2011/10/18
To investigate the structure and composition of the dusty interstellar medium (ISM) of low surface brightness (LSB) disk galaxies, we have used multiwavelength photometry to construct spectral energy ...
Genesis of the dusty Universe: modeling submillimetre source counts
galaxies: evolution – galaxies: general – galaxies: starburst – infrared:galaxies – submillimetre: galaxies
font style='font-size:12px;'>
2011/10/13
We model the evolution of IR galaxies using a phenomenological approach to match the observed source counts at different IR wavelengths. We introduce a new algorithm for reproducing source counts base...

HALOGAS: HI Observations Modeling Nearby Edge-on Spiral
font style='font-size:12px;'>
2011/10/12
We present 21-cm observations and models of the HI kinematics and distribution of NGC 4244, a nearby edge-on Scd galaxy observed as part of the Westerbork Hydrogen Accretion in LOcal GAlaxieS (HALOGAS...
Modeling blue stragglers in young clusters

font style='font-size:12px;'>
2011/10/12
In this paper, a grid of the binary evolution models are calculated for the study of blue straggler (BS) population in intermediate age ($\log Age$=7.85-8.95) star clusters. The BS formation via mass ...
Nonradial and nonpolytropic astrophysical outflows IX. Modeling T Tauri jets with a low mass-accretion rate
MHD, Stars: pre-main sequence, Stars: winds, outfl ows, Stars: mass-loss, Stars: rotation, ISM
font style='font-size:12px;'>
2011/10/8
Context: A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity. The disk-locking mechanism has been shown to ...

Modeling differential rotation rapidly rotating solar-type stars
font style='font-size:12px;'>
2011/10/9
We investigate differential rotation in rapidly rotating solar-type stars by means of an axisymmetric mean field model that was previously applied to the sun. This allows us to calculate the latitudin...
Stochastic Acceleration and the Evolution of Spectral Distributions in SSC Sources: A Self Consistent Modeling of Blazars' Flares
Stochastic Acceleration Evolution Spectral Distributions
font style='font-size:12px;'>
2011/9/30
The broad-band spectral distributions of non-thermal sources, such as those of several known blazars, are well described by a log-parabolic fit. The second degree term in these fits measures the curva...
Multi-wavelength modeling of the spatially resolved debris disk of HD 107146

2011/9/28
We aim to constrain the location, composition, and dynamical state of planetesimal populations and dust around the young, sun-like (G2V) star HD 107146}. We consider coronagraphic observations obtaine...
