DRAGONS -- A Quick Overview
Kathleen Labrie, Chris Simpson, Ricardo Cardenes +10
DRAGONS (Data Reduction for Astronomy from Gemini Observatory North and South) is a platform for the reduction and processing of astronomical data. The Python-based, open-source pa…
Survey for Distant Solar Twins (SDST) -- III. Identification of new solar twin and solar analogue stars
Christian Lehmann, Michael T. Murphy, Fan Liu +3
The Survey for Distant Solar Twins (SDST) aims to find stars very similar to the Sun at distances 1-4 kpc, several times more distant than any currently known solar twins and analo…
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…
Relativistic frequency shifts in Cr, Ti, Fe, Ni, Ca, Na, and V to search for variation in the fine structure constant
V. A. Dzuba, V. V. Flambaum, M. T. Murphy +1
Sensitivity of the frequencies of twenty two atomic transitions to the variation of the fine structure constant is calculated. The findings are to be used in search for possibl…
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,…
