Primordial Lithium from Globular Cluster Turn-Off Stars: M13 AND M71
Ann Merchant Boesgaard, Constantine P. Deliyannis
During Big Bang nucleosynthesis (BBN) in the first 15 minutes of the Universe some Li was created along with isotopes of H and He. The determination of that primordial value of…
Lithium in Turn-off Stars in the Globular Cluster M5: A Quest for Primordial Lithium
Ann Merchant Boesgaard, Constantine P. Deliyannis
The light element lithium is formed by nucleosynthesis during the Big Bang. Its abundance can help to define the parameters of the early universe. To find this primordial value, it…
Iron-Peak Element Abundances in Warm Very Metal-Poor Stars
Christopher Sneden, Ann Merchant Boesgaard, John J. Cowan +3
We have derived new detailed abundances of Mg, Ca, and the Fe-group elements Sc through Zn (Z = 21-30) for 37 main sequence turnoff very metal-poor stars ([Fe/H] <= -2.1). We analy…
Intriguing Revelations from Lithium, Beryllium, and Boron
Ann Merchant Boesgaard
This is a report on some highlights of some research on the rare light elements, lithium (Li), beryllium (Be), and boron (B), that I presented in my Henry Norris Russell Lecture in…
Lithium and Beryllium in One Solar Mass Stars
Ann Merchant Boesgaard, Constantine P. Deliyannis, Michael G. Lum +1
The surface content of lithium (Li) and beryllium (Be) in stars can reveal important information about the temperature structure and physical processes in their interior regions. T…
Lithium and Beryllium in NGC 752 -- An Open Cluster Twice the Age of the Hyades
Ann Merchant Boesgaard, Michael G. Lum, Ashley Chontos +1
The surface abundances of the light elements lithium (Li) and beryllium (Be) reveal information about the physical processes taking place in stellar interiors. The investigation of…
