Constraints on ultracompact minihalos from extragalactic γ-ray background
Yupeng Yang, Lei Feng, Xiaoyuan Huang +3
It has been proposed that ultracompact minihalos (UCMHs) might be formed in earlier epoch. If dark matter consists of Weakly Interacting Massive Particles (WIMPs), UCMHs can be tre…
The Abundance of New Kind of Dark Matter Structures
Yupeng Yang, Xuelei Chen, Tan Lu +1
A new kind of dark matter structures, ultracompact minihalos (UCMHs) was proposed recently. They would be formed during the radiation dominated epoch if the large density perturbat…
Testing three derivative methods of stellar population synthesis models
Yu Zhang, Zhanwen Han, Jinzhong Liu +2
The number of methods used to study the properties of galaxies is increased, and testing these methods is very important. Galactic globular clusters (GCs) provide an excellent medi…
Atmospheric fluctuations below 0.1 Hz during drift-scan solar diameter measurements
Costantino Sigismondi, Andrea Raponi, Giulia De Rosi +6
Measurements of the power spectrum of the seeing in the range 0.001-1 Hz have been performed in order to understand the criticity of the transits' method for solar diameter monitor…
The Hamburg/ESO R-process Enhanced Star survey (HERES)VII. Thorium abundances in metal-poor stars
Jing Ren, Norbert Christlieb, Gang Zhao
We report thorium abundances for 77 metal-poor stars in the metallicity range of -3.5<[Fe/H]}<-1.0, based on "snapshot" spectra obtained with VLT-UT2/UVES during the HERES Survey.…
The relationships of solar flares with both sunspot and geomagnetic activity
Z. L. Du, H. N. Wang
The relationships between solar flare parameters (total importance, time duration, flare index, and flux) and sunspot activity (Rz) as well as those between geomagnetic activity (a…
Predicting the solar maximum with the rising rate
Z. L. Du, H. N. Wang
The growth rate of solar activity in the early phase of a solar cycle has been known to be well correlated with the subsequent amplitude (solar maximum). It provides very useful in…
Correlations between CME parameters and sunspot activity
Z. L. Du
Smoothed monthly mean coronal mass ejection (CME) parameters (speed, acceleration, central position angle, angular width, mass and kinetic energy) for Cycle 23 are cross-analyzed,…
Metal-poor hypervelocity star candidates from the Sloan Digital Sky Survey
Yinbi Li, Ali Luo, Gang Zhao +3
Hypervelocity stars are believed to be ejected out from the Galactic center through dynamical interactions of (binary) stars with the central massive black hole(s). In this letter,…
Measurement of halo properties with weak lensing shear and flexion
Xinzhong Er, Ismael Tereno, Shude Mao
We constrain properties of cluster haloes by performing likelihood analysis using lensing shear and flexion data. We test our analysis using two mock cluster haloes: an isothermal…
VLBI observations of 10 CSO candidates: expansion velocities of hot spots
Tao An, Fang Wu, Jun Yang +11
Observations of ten Compact Symmetric Objects ({\rm CSO}) candidates have been made with the Very Long Baseline Array at 8.4 GHz in 2005 and with a combined Chinese and European VL…
Circumbinary Planets Orbiting the Rapidly Pulsating Subdwarf B-type binary NY Vir
S. -B. Qian, L. -Y. Zhu, Z. -B. Dai +3
We report here the tentative discovery of a Jovian planet in orbit around the rapidly pulsating subdwarf B-type (sdB-type) eclipsing binary NY Vir. By using new determined eclipse…
Chromospheric activity on the RS Canum Venaticorum stars
Zhang Liyun, Gu Shenghong
Firstly, we review the stellar chromospheric activity in the optical wavelength. Secondly, we introduce our ongoing project of multi-wavelength high--resolution optical observation…
The Bulge Radial Velocity Assay (BRAVA): II. Complete Sample and Data Release
Andrea Kunder, Andreas Koch, R. Michael Rich +13
We present new radial velocity measurements from the Bulge Radial Velocity Assay (BRAVA), a large scale spectroscopic survey of M-type giants in the Galactic bulge/bar region. The…
Photometric Study of Neglected Eclipsing Binary GSC 3576-0170
Zhang Liyun, Jing Jianghong, Tang Yanke +1
The new multi-color photometric light curves of the short-period eclipsing binary GSC 3576-0170 were obtained on two consecutive nights (October 5 and 6, 2009). With the 200…
Binary interactions on the calibrations of star formation rate
F. Zhang, L. Li, Y. Zhang +2
Using the evolutionary population synthesis (EPS) models with and without binary interactions (BIs), we present L_Ha, L_[OII], L_{i,UV} and L_FIR for Burst, S0, Sa-Sd and Irr galax…
Temporal Variation of the Hemispheric Solar Rotation
J. -L. Xie, X. -J. Shi, J. -C. Xu
The daily sunspot numbers of the whole disk as well as the northern and southern hemispheres from January 1, 1945 to December 31, 2010 are used to investigate the temporal variatio…
Where do the Progenitors of Millisecond Pulsars come from?
Ali Taani, Chengmin Zhang, Mashhoor Al-Wardat +1
Observations of a large population of Millisecond Pulsars (MSPs) show a wide divergence in the orbital periods (from approximately hours to a few months). In the standard view, Low…
The short-period limit of contact binaries
Dengkai Jiang, Zhanwen Han, Hongwei Ge +2
The stability of mass transfer is important in the formation of contact binaries from detached binaries when the primaries of the initially detached binaries fill their Roche lobes…
Black Holes in the Universe: Generalized Lemaitre-Tolman-Bondi Solutions
Changjun Gao, Xuelei Chen, You-Gen Shen +1
We present new exact solutions {which presumably describe} black holes in the background of a spatially flat, pressureless dark matter (DM)-, or dark matter plus dark energy (DM+DE…
