Was Entropy Conserved between BBN and Recombination?
Alexander C. Sobotka, Adrienne L. Erickcek, Tristan L. Smith
We test the assumption of entropy conservation between Big Bang nucleosynthesis and recombination by considering a massive particle that decays into a mixture of photons and other…
The Karl G. Jansky Very Large Array Sky Survey (VLASS). Science case and survey design
M. Lacy, S. A. Baum, C. J. Chandler +75
The Very Large Array Sky Survey (VLASS) is a synoptic, all-sky radio sky survey with a unique combination of high angular resolution (2.5"), sensitivity (a 1 goal of 70…
On the Iron Abundance Anomaly in K-dwarf and Hyades Stars
Patrick D. Aleo, Alexander C. Sobotka, Ivan Ramirez
Using standard 1D-LTE model atmosphere analysis, we provide an in-depth investigation of iron abundance as derived from neutral and singly ionization iron lines (Fe {\scriptsize{I,…
The dissimilar chemical composition of the planet-hosting stars of the XO-2 binary system
I. Ramirez, S. Khanal, P. Aleo +7
Using high-quality spectra of the twin stars in the XO-2 binary system, we have detected significant differences in the chemical composition of their photospheres. The differences…
