On the nature of the flares from three candidate tidal disruption events
Y. Lu, Z. Zheng, S. N. Zhang +1
The X-ray flares of NGC 5905, RX J1242.6-1119A, and RX J1624.9+7554 observed by Chandra in 2001 and 2002 have been suggested as the candidate tidal disruption events. The distinct…
The blueshift of the [O III] emission line in NLS1s
W. Bian, Q. Yuan, Y. Zhao
We investigate the radial velocity difference between the narrow emission-line components of [O III] 5007 and H in a sample of 150 SDSS NLS1s. Seven "blue outliers" with [O…
Effects of dark-matter density profiles on bulge formation in very late-type galaxies
Jie-Hao Huang, Zu-Gan Deng, Yan-Ning Fu
The dynamical evolution of super star clusters has been investigated in dark matter halos depicted with a cuspy- or soft-core density profile. The simulations show that (1) exponen…
Bulge formation in very late-type galaxies
YanNing Fu, JieHao Huang, ZuGan Deng
The dynamical evolution of super star clusters (SSCs) moving in the background of a dark matter halo has been investigated as a possible event responsible for the formation of bulg…
Relation between and : A simulation study
Y. N. Fu, J. H. Huang, Z. G. Deng
The dynamical evolution of super star clusters (SSCs) moving in the background of dark matter halo has been investigated as a possible event causing the observed correlation betwee…
Formation of binary millisecond pulsars with relatively high surface dipole magnetic fields
W. Sutantyo, X. -D. Li
We have carried out numerical evolutionary calculations of binary systems to investigate the formation of binary millisecond pulsars (pulsars with white dwarf companions). We apply…
