Radiation fields by intermediate-age stellar populations with binaries as ionizing sources of H II regions
F. Zhang, L. Li, L. Cheng +4
Radiation fields emitted by O, B-type stars or young stellar populations (SPs) are generally considered as significant central ionizing sources (CISs) of classic H II regions. In o…
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)…
Discovery of the first wide L dwarf + giant binary system and eight other ultra-cool dwarfs in wide binaries
Z. H. Zhang, D. J. Pinfield, A. C. Day-Jones +11
We identify 806 ultra-cool dwarfs from their SDSS riz photometry (of which 34 are newly discovered L dwarfs) and obtain proper motions through cross matching with UKIDSS and 2MASS.…
A possible solution for the lack of EHB binaries in globular clusters
Z. Han
The binary fraction among extreme horizontal branch (EHB) stars in Galactic globular clusters (GCs) is an order of magnitude lower than the binary fraction among their counterparts…
