    • Constraining Nucleosynthesis in Two CEMP Progenitors Using Fluorine 

      Mura-Guzmán, A.; Yong, D.; Abate, C.; Karakas, A.; Kobayashi, C.; Oh, H.; Chun, S.; Mace, G.; . (2020-11-01)
      We present new fluorine abundance estimations in two carbon enhanced metal-poor (CEMP) stars, HE 1429-0551 and HE 1305+0007. HE 1429-0551 is also enriched in slow neutron-capture process (s-process) elements, a CEMP-s, and ...

S.; Palle, E.; Berdinas, Z. M.; Coleman, G. A. L.; Diaz, M. R.; Ribas, I.; Jones, H. R. A.; Butler, R. P.; Tinney, C. G.; Bailey, J.; Carter, B. D.; ~O'Toole, S.; Wittenmyer, R. A.; Crane, J. D.; Feng, F.; Shectman, S. A.; Teske, J.; Reiners, A.; Amado, P. J.; Anglada-Escude, G.; . (2020-06-26)
      The closet exoplanets to the Sun provide opportunities for detailed characterization of planets outside the Solar System. We report the discovery, using radial velocity measurements, of a compact multiplanet system of ...
