Are there any first-generation stars in globular clusters today?
Charbonnel, C.; Chantereau, W.; Krause, M.; Primas, F.; Wang, Y. (2014-09-22)Context. Several models compete to explain the abundance properties of stellar populations in globular clusters. One of the main constraints is the present-day ratio of first- and second-generation stars that are currently ... -
Boron depletion in 9 to 15 M(circle dot) stars with rotation
Frischknecht, U.; Hirschi, R.; Meynet, G.; Ekstroem, S.; Georgy, C.; Rauscher, T.; Winteler, C.; Thielemann, F-K. (Cambridge University Press, 2010)The treatment of mixing is still one of the major uncertainties in stellar evolution models. One open question is how well the prescriptions for rotational mixing describe the real effects. We tested the mixing prescriptions ... -
Boron in the very metal-poor star BD-13 3442
Duncan, D.K.; Rebull, L.M.; Primas, F.; Boesgaard, A.M.; Deliyannis, C.P.; Hobbs, L.M.; King, J.R.; Ryan, Sean G. (1998)The Goddard High Resolution Spectrograph (GHRS) of the Hubble Space Telescope (HST) has been used to observe the boron 2500 °A region of BD −13 3442. At a metallicity of [Fe/H]=−3.00 this is the most metal- poor star ever ... -
