Grids of rotating stellar models with masses between 1.0 and 3.0 Msun

Wuming Yang, Shaolan Bi, Xiangcun Meng

We calculated a grid of evolutionary tracks of rotating models with masses between 1.0 and 3.0 and a resolution , which can be used to study t…

Asteroseismology of the ZZ Ceti star HS 0507+0434B

J. -N. Fu, N. Dolez, G. Vauclair +14

The pulsating DA white dwarfs (ZZ Ceti stars) are -mode non-radial pulsators. Asteroseismology provides strong constraints on their global parameters and internal structure. Sin…

Type IIn Supernova SN 2010jl: Optical Observations for Over 500 Days After Explosion

Tianmeng Zhang, Xiaofeng Wang, Chao Wu +16

We present extensive optical observations of a Type IIn supernova (SN) 2010jl for the first 1.5 years after the discovery. The UBVRI light curves demonstrated an interesting two-st…

Analysis of a selected sample of RR Lyrae stars in LMC from OGLE III

B. -Q. Chen, B. -W. Jiang, M. Yang

A systematic study of RR Lyrae stars is performed based on a selected sample of 655 objects in the Large Magellanic Cloud with observation of long span and numerous measurements by…

A Statistical Study on Force-Freeness of Solar Magnetic Fields in the Photosphere

S. Liu, J. T. Su, H. Q. Zhang +4

It is an indisputable fact that solar magnetic fields are force-free in the corona, where force free fields means that current and magnetic fields are parallel and there is no Lore…

The birth rate of supernovae from double-degenerate and core-degenerate systems

Xiangcun Meng, Wuming Yang

We make a series of Monte Carlo simulations by a rapid binary evolution code and take two treatments of CE evolution, i.e. -formalism and -algorithm. We find that only for th…

The Period-Luminosity Relation of Red Supergiant Stars in the Small Magellanic Cloud

Ming Yang, B. W. Jiang

The characteristics of light variation of RSGs in SMC are analyzed based on the nearly 8-10 year long data collected by the ASAS and MACHO projects. The identified 126 RSGs are cla…

Predicting the Fate of Binary Red Giants Using the Observed Sequence E Star Population: Binary Planetary Nebula Nuclei and Post-RGB Stars

J. D. Nie, P. R. Wood, C. P. Nicholls

Sequence E variables are close binary red giants that show ellipsoidal light variations. They are likely the immediate precursors of planetary nebulae (PNe) with close binary centr…

Revision of Solar Spicule Classification

Y. Z. Zhang, K. Shibata, J. X. Wang +4

Solar spicules are the fundamental magnetic structures in the chromosphere and considered to play a key role in channelling the chromosphere and corona. Recently, it was suggested…

Characteristics of solar-like oscillations of secondary red clump stars

Wuming Yang, Xiangcun Meng, Shaolan Bi +4

We calculated the populations of core-helium-burning (CHeB) stars and found that the secondary red clump (SRC) stars can form an SRC peak in the distributions of the frequency of m…

The Debris Disk Candidates: Eleven 24m excess stars in Spitzer SWIRE Fields

Hong Wu, Chao-Jian Wu, Chen Cao +2

We present the optical to mid-infrared SEDs of 11 debris disk candidates from SWIRE fields. All these candidates are selected from SWIRE 24m sources matched with both…
