Abstract Telluric absorption lines impact the measuring of precise radial velocities (RVs) from high-resolution ground-based spectrographs. In this paper, we simulate dependence on stellar spectral type and extend work first paper in series, which studied a G-type star, to synthetic M-dwarf star. We quantify bias RV measurements visible near-infrared (NIR) presence tellurics simulated set obser...

With the era of big data, prediction and evaluation geological mineral resources have gradually entered into a new stage from digital prospecting to intelligent prospecting. The theoretical method data mining can contribute deep resource evaluation. This paper extracts ore-causing ore-caused anomaly information based on text technology, constructs regional conceptual model data. First, we set u...

A method has been developed to load tellurium into liquid scintillator so as permit searches for neutrinoless double beta decay with high sensitivity. The approach involves the synthesis of an oil-soluble compound from telluric acid and organic diol. process utilises distillable chemicals that can be safely handled underground affords low radioactive backgrounds, optical absorption light yields...

Abstract We report on the measurements of telluric water vapor made with instrument FIFI-LS SOFIA. Since November 2018, has measured overburden same measurement setup each science flight about 10 data points throughout flight. This created a large sample 469 at different locations, altitudes and seasons. The paper describes principle in detail provides some trend analysis 3 parameters. presents...
