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…

Constraints on Dark Energy Models Including Gamma Ray Bursts

Hong Li, Meng Su, Zuhui Fan +2

In this paper we analyze the constraints on the property of dark energy from cosmological observations. Together with SNe Ia Gold sample, WMAP, SDSS and 2dFGRS data, we include 69…

On Secular Resonances of Small Bodies in the Planetary Systems

Ji Jianghui, Liu Lin, Li Guangyu

We investigate the secular resonances for massless small bodies and Earth-like planets in several planetary systems. We further compare the results with those of Solar System. For…

Measuring Neutron Star Mass and Radius with Three Mass-Radius Relations

C. M. Zhang, H. X. Yin, Y. Kojima +5

We propose to determine the mass and the radius of a neutron star (NS) using three measurable mass-radius relationships, namely the ``apparent'' radius inferred from neutron star t…

The accretion ratios in Seyfert 2 galaxies with and without hidden broad-line regions

W. Bian, Q. Gu

Using a large sample of 90 Seyfert 2 galaxies (Sy2s) with spectropolarimetric observations, we tested the suggestion that the presence of hidden broad-line regions (HBLRs) in Sy2s…

The Secular Evolution and Dynamical Architecture of the Neptunian Triplet Planetary System HD 69830

Ji Jianghui, H. Kinoshita, Liu Lin +1

We perform numerical simulations to study the secular orbital evolution and dynamical structure in the HD 69830 system with the best-fit orbital solutions by Lovis and coworkers (2…
