New method for determining the thickness of non-edge-on disk galaxies
Yinghe Zhao, Qiuhe Peng, Tao Hu
In this paper we report a new method for determining the thickness of the non-edge-on disk galaxies. Our method is based on the observation comparing with the theoretical researche…
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…
Elliptical Galaxies with Emission Lines from the Sloan Digital Sky Survey
Ying-He Zhao, Qiu-Sheng Gu, Zhi-Xin Peng +3
We present the results of 11 elliptical galaxies with strong nebular emission lines during our study of star formation history along the Hubble sequence. After removing the dilutio…
Spectroscopic Study of SU UMa-type Dwarf Nova YZ Cnc during its 2002 Superoutburst
Ying-he Zhao, Zong-yun Li, Xiao-an Wu +1
We report time-resolved spectroscopic observations of the SU Ursae Majoris dwarf nova, YZ Cnc, for 2 nights over 11 hrs during its 2002 January superoutburst. The spectra only show…
Phase Transition Between superfluid and Normal states of Neutrons in Neutron Stars--The Origin of Glitches of Pulsars
Q. H. Peng, Z. Q. Luo
Starting from a neutron star heating mechanism by the magnetic dipole radiation from the 3^P_2 neutron superfluid vortices in neutron stars, we propose a neutron phase oscillation…
