Boron Depletion in F and G Dwarf Stars and the Beryllium-Boron Correlation by Boesgaard, Ann Merchant, Deliyannis, Constantine P, Steinhauer, Aaron

“…Boron provides a special probe below the stellar surface since it survives to greater depths than do Li and Be. To search for B depletions we have observed B…”

Lithium and Lithium Depletion in Halo Stars on Extreme Orbits by Boesgaard, Ann Merchant, Stephens, Alex, Deliyannis, Constantine P

“…We have determined Li abundances in 55 dwarfs and subgiants that are metal-poor (-3.6 < [Fe/H] < -0.7) and have extreme orbital kinematics. Our purpose is to…”

Beryllium in the Ultra-Lithium-deficient, Metal-Poor Halo Dwarf G186-26 by Boesgaard, Ann Merchant, Novicki, Megan C

“…The vast majority of low-metal halo dwarfs show a similar amount of Li; this has been attributed to the Li that was produced in the big bang. However, there…”
