A limit on variations in the fine-structure constant from spectra of nearby Sun-like stars
Michael T. Murphy, Daniel A. Berke, Fan Liu +4
The fine structure constant, , sets the strength of the electromagnetic force. The Standard Model of particle physics provides no explanation for its value, which could potentia…
Survey for Distant Solar Twins (SDST) -- II. Design, observations and data
Fan Liu, Michael T. Murphy, Christian Lehmann +5
Studies of solar twins have key impacts on the astronomical community, but only 100--200 nearby solar twins ( 1 kpc) have been reliably identified over the last few decade…
Probing Galactic variations in the fine-structure constant using solar twin stars: systematic errors
Daniel A. Berke, Michael T. Murphy, Chris Flynn +1
Sun-like stars are a new probe of variations in the fine-structure constant, , via the solar twins approach: velocity separations of close pairs of absorption lines are compared…
Probing Galactic variations in the fine-structure constant using solar twin stars: methodology and results
Daniel A. Berke, Michael T. Murphy, Chris Flynn +1
The rich absorption spectra of Sun-like stars are enticing probes for variations in the fine-structure constant, , which gauges the strength of electromagnetism. While individua…
Detailed chemical compositions of planet-hosting stars: II. Exploration of the interiors of terrestrial-type exoplanets
Haiyang S. Wang, Sascha P. Quanz, David Yong +4
A major goal in the discovery and characterisation of exoplanets is to identify terrestrial-type worlds that are similar to (or otherwise distinct from) our Earth. Recent results h…
Survey for Distant Solar Twins (SDST) -- I. EPIC method for stellar parameter measurement
Christian Lehmann, Michael T. Murphy, Fan Liu +2
Solar twins are stars of key importance to the field of astronomy and offer a multitude of science applications. Only a small number () of solar twins are known today,…
