Photometry and Spectroscopy of KS Ursae Majoris during Superoutburst
Yinghe Zhao, Zongyun Li, Xiaoan Wu +3
We report photometric and spectroscopic observations of the SU UMa-type dwarf novae, KS Ursae Majoris, during its 2003 February superoutburst. Modulations with a period of $0.07017…
Polar Outflows in Six Broad Absorption Line Quasars
Hongyan Zhou, Tinggui Wang, Huiyuan Wang +3
Using the radio observations by FIRST and NVSS, we build a sample of 151 radio variable quasars selected from the Sloan Digital Sky Survey Data Release 3 (SDSS DR3). Six (probably…
XMM-Newton view of PKS 2155-304: hardness ratio and cross-correlation analysis of EPIC pn observations
Y. H. Zhang, A. Treves, L. Maraschi +2
With currently available XMM-Newton EPIC pn observations spanned over about 3 years, we present a detailed spectral and temporal variability of the 0.2--10 keV X-ray emission from…
Envelope Expansion with Core Collapse II. Quasi-Spherical Self-Similar Solutions for an Isothermal Magnetofluid
Cong Yu, Yu-Qing Lou
We investigate self-similar magnetohydrodynamic (MHD) processes in an isothermal self-gravitating fluid with a quasi-spherical symmetry and extend the envelope expansion with core…
Spectral lags caused by the Doppler effect of fireballs
R. -J. Lu, Y. -P. Qin, Z. -B. Zhang +1
Recently, Shen et al. (2005) studied the contributions of curvature effect of fireballs to the spectral lag and showed that the observed lags could be accounted for by the effect.…
Evolutionary Population Synthesis for Binary Stellar Population at High Spectral Resolution: Integrated Spectral Energy Distributions and Absorption-feature Indices
Fenghui Zhang, Lifang Li, Zhanwen Han
Using EPS we present high resolution (0.3 Å, HRes) ISEDs from 3000 to 7000 Åand Lick/IDS absorption-line indices, for an extensive set of instantaneous burst binary stellar populat…
Relationship between the rise width and the full width of gamma-ray burst pulses and its implications in terms of the fireball model
Rui-Jing Lu, Yi-Ping Qin, Ting-Feng Yi
Kocevski et al. (2003) found that there is a linear relation between the rise width and the full width of gamma-ray burst pulses detected by the BATSE instrument based on their emp…
Spectral state transitions in low-mass X-ray binaries - the effect of hard and soft irradiation
B. F. Liu, F. Meyer, E. Meyer-Hofmeister
In neutron star and black hole X-ray binaries the transitions between the two spectral states, hard and soft, signals the change between accretion via a hot advection-dominated flo…
XMM-Newton View of PKS 2155-304: Characterizing the X-ray Variability Properties with EPIC-PN
Y. H. Zhang, A. Treves, A. Celotti +2
Starting from XMM-Newton EPIC-PN data, we present the X-ray variability characteristics of PKS 2155-304 using a simple analysis of the excess variance, \xs, and of the fractional r…
The FWHM of local pulses and the corresponding power-law index of gamma-ray burst FRED pulses
L. -W. Jia, Y. -P. Qin
The FWHM of gamma-ray burst (GRB) pulses is known to be related with energy by a power-law. We wonder if the power-law index is related with the corresponding local pulse width…
Testing the Universal Structured Jet Models of Gamma-Ray Bursts by BATSE Observations
X. H. Cui, E. W. Liang, R. J. Lu
Assuming that the observed gamma-ray burst (GRB) rate as a function of redshift is proportional to a corrected star formation rate, we derive the empirical distribution of the view…
Deviation of light curves of gamma-ray burst pulses from standard forms due to the curvature effect of spherical fireballs or uniform jets
Y. -P. Qin, R. -J. Lu
As revealed previously, under the assumption that some pulses of gamma-ray bursts are produced by shocks in spherical fireballs or uniform jets of large opening angles, there exist…
On the difference between type E and A OH/IR stars
J. H. He, P. S. Chen
The observed SEDs of a sample of 60 OH/IR stars are fitted using a radiative transfer model of a dusty envelope. Among the whole sample, 21 stars have reliable phase-lag distances…
Method of determining cosmological parameter ranges with samples of candles with an intrinsic distribution
Yi-Ping Qin, Bin-Bin Zhang, Yun-Ming Dong +8
In this paper, the effect of the intrinsic distribution of cosmological candles is investigated. We find that, in the case of a narrow distribution, the deviation of the observed m…
