Palladium and silver abundances in stars with [Fe/H] > -2.6
Xiaoshu Wu, Liang Wang, Jianrong Shi +2
Palladium (Pd) and silver (Ag) are the key elements for probing the weak component in the rapid neutron-capture process (r-process) of stellar nucleosynthesis. We performed a detai…
Calibrating the α parameter of convective efficiency using observed stellar properties
X. S. Wu, S. Alexeeva, L. Mashonkina +3
Context. Synthetic model atmosphere calculations are still the most commonly used tool when determining precise stellar parameters and stellar chemical compositions. Besides three-…
Comb-calibrated solar spectroscopy through a multiplexed single-mode fiber channel
R A Probst, L Wang, H-P Doerr +7
We investigate a new scheme for astronomical spectrograph calibration using the laser frequency comb at the Solar Vacuum Tower Telescope on Tenerife. Our concept is based upon a si…
Spectroscopic analysis of metal-poor stars from LAMOST: early results
Hai-Ning Li, Gang Zhao, Norbert Christlieb +5
We report on early results from a pilot program searching for metal-poor stars with LAMOST and follow-up high-resolution observation acquired with the MIKE spectrograph attached to…
The Pan-Pacific Planet Search. II. Confirmation of a two-planet system around HD 121056
Robert A. Wittenmyer, Liang Wang, Fan Liu +5
Precise radial velocities from the Anglo-Australian Telescope confirm the presence of a rare short-period planet around the K0 giant HD 121056. An independent two-planet solution u…
Asteroseismic based estimation of the surface gravity for the LAMOST giant stars
Chao Liu, Min Fang, Yue Wu +7
Asteroseismology is one of the most accurate approaches to estimate the surface gravity of a star. However, most of the data from the current spectroscopic surveys do not have aste…
