A Comprehensive Study of the Relations between the Properties of Planetary Systems and the Chemical Compositions of Their Host Stars

The Astrophysical Journal
The giant planet–metallicity correlation revealed that planetary formation depends on the stellar properties. There is growing evidence that it is also valid for smaller hot planets, but it is not clear whether elements other than iron also influence the

The TESS-Keck Survey. XVII. Precise Mass Measurements in a Young, High-multiplicity Transiting Planet System Using Radial Velocities and Transit Timing Variations

The Astronomical Journal
We present a radial velocity (RV) analysis of TOI-1136, a bright Transiting Exoplanet Survey Satellite (TESS) system with six confirmed transiting planets, and a seventh single-transiting planet candidate.

Determination of 10 Trace Impurity Elements in Titanium and Titanium Alloys with DC Arc Atomic Emission Spectrometry

Yankuang ceshi, 2014
High purity titanium and titanium alloy have good plasticity, but with the presence of impurity, their performance will become brittle and hard. The accurate quantitative analysis of impurity elements is useful for carrying on the quality control of ...
