Relationship between the gamma-ray burst pulse width and energy due to the Doppler effect of fireballs
Y. -P. Qin, Y. -M. Dong, R. -J. Lu +2
We study in details how the pulse width of gamma-ray bursts is related with energy under the assumption that the sources concerned are in the stage of fireballs. Due to the Doppler…
Hot subdwarfs from the ESO Supernova Ia Progenitor Survey - I. Atmospheric parameters and cool companions of sdB stars
T. Lisker, U. Heber, R. Napiwotzki +4
We present the analysis of a high-resolution, high-quality sample of optical spectra for 76 subdwarf B (sdB) stars from the ESO Supernova Ia Progenitor Survey (SPY). Effective temp…
Effects of chemical composition and thermohaline mixing on the accreting components for low--mass close binaries: application to blue stragglers
X. Chen, Z. Han
We studied the effects of surface composition and thermohaline mixing caused by secular instability on the accreting components for low--mass binaries and applied the results on a…
Distribution of the extensive Doppler redshift of quasars
Yi-Ping Qin, Hong-Tao Liu, En-Wei Liang +2
We make an analysis of the distribution of the extensive Doppler redshift defined as with a sample of 1317 absorption redshifts a…
Constraining and Dark Energy with Gamma-Ray Bursts
Z. G. Dai, E. W. Liang, D. Xu
An relationship with a small scatter for current -ray burst (GRB) data was recently reported, where is the beaming-correc…
Testing the Predictions of the Universal-Structured Jet Model of Gamma-Ray Bursts by Simulations
E. W. Liang, X. F. Wu, Z. G. Dai
Based on the standard energy reservoir of gamma-ray burst (GRB) jets and the relationship between peak energy () of spectrum and the equivalent-isotropic energy ($E_{\r…
Doppler effect of gamma-ray bursts in the fireball framework
Yi-Ping Qin, Fu-Wen Zhang
The influence of the Doppler effect in the fireball framework on the spectrum of gamma-ray bursts is investigated. The study shows that the shape of the expected spectrum of an exp…
Jet break time -- flux density relationship and constraints on physical parameters of GRB afterglows
X. F. Wu, Z. G. Dai, E. W. Liang
We derive a relation between the flux density at the light-curve break of a gamma-ray burst (GRB) afterglow and the break time . The break is due to the transition…
The WEBT BL Lacertae Campaign 2001 and its extension
M. Villata, C. M. Raiteri
BL Lacertae has been the target of four observing campaigns by the Whole Earth Blazar Telescope (WEBT) collaboration. In this paper we present light curves obtained by the…
The Luminosity - E_p Relation within Gamma--Ray Bursts and Implications for Fireball Models
E. W. Liang, Z. G. Dai, X. F. Wu
Using a sample of 2408 time-resolved spectra for 91 BATSE gamma-ray bursts (GRBs) presented by Preece et al., we show that the relation between the isotropic-equivalent luminosity…
Structure and evolution of low mass W UMa type systems
Lifang Li, Zhanwen Han, Fenghui Zhang
The structure and evolution of low mass W UMa type contact binaries are discussed by employing Eggleton's stellar evolution code. Assuming that these systems completely satisfy Roc…
Gamma-ray Emission Properties from Mature Pulsars in the Galaxy and in the Gould Belt
K. S. Cheng, L. Zhang, P. Leung +1
We study the -ray emission properties of pulsars by using a new self-consistent outer gap model. The outer gap can exist in pulsars with age over million years old if the effect…
The Peak Energy Distribution of the nu F_nu Spectra and the Implications for the Jet Structure Models of Gamma-Ray Bursts
E. W. Liang, Z. G. Dai
We study the peak energy () distribution of the spectra of gamma-ray bursts (GRBs) and X-ray flashes (XRFs) with a sample of 57 bursts observed by {\em High Ener…
Gamma-ray Luminosity and Death Lines of Pulsars with Outer Gaps
L. Zhang, K. S. Cheng, Z. J. Jiang +1
We re-examine the outer gap size by taking the geometry of the dipole magnetic field into account. Furthermore, we also consider that instead of taking the gap size at half of the…
Emission and absorption lines of gamma-ray bursts affected by the relativistic motion of fireball ejecta
Yi-Ping Qin
We display by numerical calculation how rest frame spectral lines appear in the observed spectrum of gamma-ray bursts due to the Doppler effect in the fireball framework. The analy…
Characteristics of profiles of gamma-ray burst pulses associated with the Doppler effect of fireballs
Yi-Ping Qin, Zhi-Bin Zhang, Fu-Wen Zhang +1
In this paper, we derive in a much detail the formula of count rates, in terms of the integral of time, of gamma-ray bursts in the framework of fireballs, where the Doppler effect…
