High-Frequency QPOs and Overstable Oscillations of Black-Hole Accretion Disks
Dong Lai, Wen Fu, David Tsang +2
The physical origin of high-frequency QPOs (HFQPOs) in black-hole X-ray binaries remains an enigma despite many years of detailed observational studies. Although there exists a num…
Effects of tidally enhanced stellar wind on the horizontal branch morphology of globular clusters
Zhen-Xin Lei, Xue-Fei Chen, Feng-Hui Zhang +1
Metallicity is the first parameter to influence the horizontal branch (HB) morphology of globular clusters (GCs). It has been found, however, that some other parameters may also pl…
Rossby Wave Instability in Accretion Discs with Large-Scale Poloidal Magnetic Fields
Cong Yu, Dong Lai
We study the effect of large-scale magnetic fields on the non-axisymmetric Rossby wave instability (RWI) in accretion discs. The instability develops around a density bump, which i…
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…
Understanding the white-light flare on 2012 March 9 : Evidence of a two-step magnetic reconnection
Q. Hao, Y. Guo, Y. Dai +4
We attempt to understand the white-light flare (WLF) that was observed on 2012 March 9 with a newly constructed multi-wavelength solar telescope called the Optical and Near-infrare…
A Metal-Strong and Dust-Rich Damped \lya Absorption System toward the Quasar SDSS J115705.52+615521.7
Jian-Guo Wang, Hong-Yan Zhou, Jian Ge +7
(Abridged for arXiv) We report the discovery of an unusual, extremely dust-rich and metal-strong damped \lya absorption system (DLA) at a redshift toward the quasar…
Uncertainties in the calibrations of star formation rate
Fenghui Zhang, Lifang Li, Xiaoyu Kang +2
The calibrations of star formation rate (SFR) are prone to be affected by many factors, such as metallicity, initial mass function (IMF), evolutionary population synthesis (EPS) mo…
Testing the core overshooting mixing described by the turbulent convection model on the eclipsing binary star HY Vir
Q. S. Zhang
Helioseismic investigation has suggested to apply the turbulent convection models (TCMs) to the convective overshooting. Using the turbulent velocity in the overshooting region det…
Yunnan-III models for Evolutionary population synthesis
F. Zhang, L. Li, Z. Han +2
We build the Yunnan-III evolutionary population synthesis (EPS) models by using the MESA stellar evolution code, BaSeL stellar spectra library and the initial mass functions (IMFs)…
The Deflection of the Two Interacting Coronal Mass Ejections of 2010 May 23-24 as Revealed by Combined In situ Measurements and Heliospheric Imaging
N. Lugaz, C. J. Farrugia, J. A. Davies +4
In 2010 May 23-24, SDO observed the launch of two successive coronal mass ejections (CMEs), which were subsequently tracked by the SECCHI suite onboard STEREO. Using the COR2 coron…
The diffusive overshooting approach on Li abundance in clusters
Q. S. Zhang
The helioseimic investigation shows that the convective overshooting can penetrate to the location where the temperature is which is the typical tempera…
Common Envelope Evolution: Where we stand and how we can move forward
N. Ivanova, S. Justham, X. Chen +16
This work aims to present our current best physical understanding of common-envelope evolution (CEE). We highlight areas of consensus and disagreement, and stress ideas which shoul…
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…
Double-peaked narrow emission-line galaxies from Sloan Digital Sky Survey. I. Sample and basic properties
Jun-Qiang Ge, Chen Hu, Jian-Min Wang +2
Recently, much attention has been given to double-peaked narrow emission-line galaxies, some of which are suggested to be related with merging galaxies. We make a systematic search…
VLBI detection of the Galactic black hole binary candidate MAXI J1836-194
Jun Yang, Yonghua Xu, Zhixuan Li +6
The X-ray transient MAXI J1836-194 is a newly-identified Galactic black hole binary candidate. As most X-ray transients, it was discovered at the beginning of an X-ray outburst. Af…
Magnetar Giant Flares --- Flux Rope Eruptions in Multipolar Magnetospheric Magnetic Fields
Cong Yu
We address a primary question regarding the physical mechanism that triggers the energy release and initiates the onset of eruptions in the magnetar magnetosphere. A self-consisten…
Microlensig Binaries with Candidate Brown Dwarf Companions
I. -G. Shin, C. Han, A. Gould +152
Brown dwarfs are important objects because they may provide a missing link between stars and planets, two populations that have dramatically different formation history. In this pa…
Testing the 130 GeV gamma-ray line with high energy resolution detectors
Ye Li, Qiang Yuan
Recently some hints of the existence of -ray line around 130 GeV are reported according to the analysis of Fermi-LAT data. If confirmed it would be the first direct evidence to…

The Evolution and Star Formation History of M33
Xiaoyu Kang, Ruixiang Chang, Jun Yin +4
We construct a parameterized model to explore the main properties of the star formation history of M33. We assume that the disk originates and grows by the primordial gas infall an…
