The t system: a new system for estimating the total magnitudes of galaxies
C. K. Young, N. Metcalfe, J. Zhu +3
We present a new, but simple, procedure for estimating the total magnitudes of galaxies. This procedure involves the out-focusing of digital galaxy images numerically, the fitting…
Studies of the Virgo cluster based on the Virgo Photometry Catalogue
C. K. Young
The `Virgo Photometry Catalogue' (VPC) is the first independently calibrated general catalogue of galaxies to cover the Virgo cluster since the `Catalog of Galaxies and Clusters of…
Quasars around the Seyfert Galaxy NGC3516
Y. Chu, J. Wei, J. Hu +2
We report redshift measurements of 5 X-ray emitting blue stellar objects (BSO's) located less than 12 arc min from the X-ray Seyfert galaxy, NGC 3516. We find these quasars to be d…
An equation of state from cool-dense fluids to hot gases for mixed elements
G. Q. Luo
An equation of state for the domain extending from hot gases to cool-dense fluids is formulated for a hydrogen-helium mixture. The physical processes take account of temperature io…
On the Consistency between the Outer Rotation Curve of the Galaxy and the Microlensing Rate towards the Large Magellanic Cloud
Zong-Hong Zhu, Xiang-Ping Wu
Recent determination of the outer rotation curve of the Galaxy suggests that the total Galactic mass is likely to concentrate into a region of radius . If this finding is…
A statistical study of the spectra of very luminous IRAS galaxies I: Data
H. Wu, Z. L. Zou, X. Y. Xia +1
This paper presents the results of spectral observations for the largest complete sample of very luminous IRAS galaxies obtained to date. The sample consists of those 73 objects fo…
Wide Field Surveys of Herbig-Haro Objects
Jun Yan, Hongchi Wang, Min Wang +3
We report our new results from wide-field surveys of Herbig-Haro (HH) objects in the nearby star forming regions. The surveys covered approximately 56 degree in Perseus, Taurus, Or…
Turbulent Convection and pulsational Stability of Variable Stars I. Oscillations of Long-Period Variables
D. R. Xiong, L. Deng, Q. L. Cheng
We have performed a linear pulsational stability survey of 6 series of long period variable models with M=1.0 Msun, L=3000 - 8000Lsun, and (X,Z)= (0.700,0.020),(0.735,0.005). The d…
Turbulent Convection and Pulsational Stability of Variable Stars II. Oscillations of RR Lyrae and Horizontal Branch Red Variable Stars
D. R. Xiong, Q. L. Cheng, L. Deng
Using a nonlocal time-dependent theory of convection, we have calculated the linear non-adiabatic oscillations of the Horizontal Branch (HB) stars, with both the dynamic and thermo…
Distance indicators based on the luminosity-profile shapes of early-type galaxies--a reply
C. K. Young, M. J. Currie, .
In a recent paper, Binggeli & Jerjen (1998) question the value of the extra- galactic distance indicators presented by Young & Currie (1994 & 1995) and state that they have refuted…
An inverse Compton scattering (ICS) model of pulsar emission
G. J. Qiao, W. P. Lin
Core and conal emission beams of radio pulsars have been identified observationally (Rankin 1983,1993; Lyne and Manchester 1988), In the inner gap model (Ruderman and Sutherland 19…
The Collapse of Neutron Stars in High-Mass Binaries as the Energy Source for the Gamma-Ray Bursts
Bo Qin, Xiang-Ping Wu, Ming-Chung Chu +2
The energy source has remained to be the great mystery in understanding of the gamma-ray bursts (GRBs) if the events are placed at cosmological distances as indicated by a number o…
Stability of a hot two-temperature accretion disc with advection
Xue-Bing Wu
The effects of radial advection and thermal diffusion were considered in investigating the linear stability of an optically thin, two-temperature accretion disc. If the disc has on…
Quasar-galaxy associations from gravitational lensing: revisited
Zong-Hong Zhu, Xiang-Ping Wu, Li-Zhi Fang
The theoretically expected amplitude of the associations of background quasars with foreground galaxies as a result of gravitational lensing has been updated in this paper. Since t…
Environmental Effect on the Associations of Background Quasars with Foreground Objects: II. Numerical Simulations
Xiang-Ping Wu, Xiao-Hong Zhu, Yi-Peng Jing +1
Using numerical simulations of cluster formation in the standard CDM model (SCDM) and in a low-density, flat CDM model with a cosmological constant (LCDM), we investigate the gravi…
A Statistical Comparison of Cluster Mass Estimates from Optical/X-ray Observations and Gravitational Lensing
Xiang-Ping Wu, Li-Zhi Fang
We present a statistical comparison of three different estimates of cluster mass, namely, the dynamical masses obtained from the velocity dispersion of optical galaxies, the X-ray…
