A New Diagnostic Method for Assessment of Stellar Stratification in Star Clusters
Dimitrios A. Gouliermis, Richard de Grijs, Yu Xin
We propose a new method for the characterization of stellar stratification in stellar systems. The method uses the mean-square radius (also called the Spitzer radius) of the system…
Results of WEBT, VLBA and RXTE monitoring of 3C 279 during 2006-2007
V. M. Larionov, S. G. Jorstad, A. P. Marscher +2
We present radio-to-optical data taken by the WEBT, supplemented by VLBA and RXTE observations, of 3C 279. Our goal is to use this extensive database to draw inferences regarding t…
Plasmoids in Reconnecting Current Sheets: Solar and Terrestrial Contexts Compared
J. Lin, S. R. Cranmer, C. J. Farrugia
Magnetic reconnection plays a crucial role in violent energy conversion occurring in the environments of high electrical conductivity, such as the solar atmosphere, magnetosphere,…
Absorption of 10--200 Gev Gamma Rays by Radiation from BLR in Blazars
H. T. Liu, J. M. Bai
In this paper, we study the photon-photon pair production optical depth for gamma-rays with energies from 10 to 200 GeV emitted by powerful blazars due to the diffuse radiation fie…
Absorption of 10 Gev--1 Tev Gamma Rays by Radiation from Broad-Line Region in 3C 279
H. T. Liu, J. M. Bai, L. Ma
In this paper, we study the photon-photon pair production optical depth for 10 GeV--1 TeV gamma rays from 3C 279 due to the diffuse radiation of broad-line region (BLR). Assuming a…
The evolutionary status of W Ursae Majoris-type systems
Lifang Li, Fenghui Zhang, Zhanwen Han +2
Well-determined physical parameters of 130 W UMa systems have been collected from the literature. Based on these data, the evolutionary status and dynamical evolution of W UMa syst…
Solar Models with Revised Abundances and Opacities
W. M. Yang, S. L. Bi
Using reconstructed opacities, we construct solar models with low heavy-element abundance. Rotational mixing and enhanced diffusion of helium and heavy elements are used to reconci…
A search for southern ultracool dwarfs in young moving groups
J. R. A. Clarke, D. J. Pinfield, M. C. Galvez-Ortiz +7
We associate 132 low-mass ultracool dwarfs in the southern hemisphere as candidate members of five moving groups using photometric and astrometric selection techniques. Of these ob…
Discovery of superstrong, fading, iron line emission and double-peaked Balmer lines of the galaxy SDSSJ0952+2143 - the light echo of a huge flare
S. Komossa, H. Zhou, T. Wang +9
We report the discovery of superstrong, fading, high-ionization iron line emission in the galaxy SDSSJ095209.56+214313.3 (SDSSJ0952+2143 hereafter), which must have been caused by…
Broad-line and Multi-wave Band Emission from Blazars
T. F. Yi, G. Z. Xie
We study the correlations of the flux of the broad-line emission () with the X-ray emission flux, optical emission flux at 5500 Åand radio emission flux at 5 GHz, respecti…
Tests for Standard Accretion Disk Models by Variability in Active Galactic Nuclei
H. T. Liu, J. M. Bai, X. H. Zhao +1
In this paper, standard accretion disk models of AGNs are tested using light curves of 26 objects well observed for reverberation mapping. Time scales of variations are estimated b…
Spins of the supermassive black hole in M87: new constraints from TeV observations
Jian-Min Wang, Yan-Rong Li, Jain-Cheng Li +1
The rapid TeV ray variability detected in the well-known nearby radio galaxy M87 implies an extremely compact emission region (5-10 Schwarzschild radii) near the horizon of the…
Radio-to-UV monitoring of AO 0235+164 by the WEBT and Swift during the 2006--2007 outburst
C. M. Raiteri, M. Villata, V. M. Larionov +2
The blazar AO 0235+164 was claimed to show a quasi-periodic behaviour in the radio and optical bands. Moreover, an extra emission component contributing to the UV and soft X-ray fl…
Optical Intra-day Variability in Blazars
A. C. Gupta, J. H. Fan, J. M. Bai +1
We selected a sample of a dozen blazars which are the prime candidates for simultaneous multi-wavelength observing campaigns in their outburst phase. We searched for optical outbur…
A New Scenario on X-ray Shallow Decay of Gamma-ray Bursts
Jirong Mao, Jiancheng Wang
In this Letter, we propose that a microphysical process takes a vital role in the shocked region in which the prompt emission of GRBs is emitted. The turbulent energy is included i…
