The Luminosity and Metallicity Relation of distant luminous infrared galaxies
Y. C. Liang, F. Hammer, H. Flores +4
Oxygen abundances [12+log(O/H)] in the interstellar medium of a large sample of distant (z>0.4) luminous infrared galaxies (LIRGs) were estimated from their extinction corrected em…

Orbital elements of barium stars formed through a wind accretion scenario
J. H. Liu, B. Zhang, Y. C. Liang +1
Taking the total angular momentum conservation in place of the tangential momentum conservation, and considering the square and higher power terms of orbital eccentricity e, the ch…

The heavy-element abundances of AGB stars and the angular momentum conservation model of wind accretion for barium stars
Y. C. Liang, G. Zhao, B. Zhang
Adpoting new s-process nucleosynthesis scenario and branch s-process path, we calculate the heavy-element abundances and C/O ratio of solar metallicity 3M_sun TP-AGB stars. The evo…
