Boron Abundances in Early B Dwarfs of the Galactic Open Cluster NGC 3293
Charles R. Proffitt, Harim Jin, Simone Daflon +4
New boron abundances or upper limits have been determined for 8 early-B stars in the young Galactic open cluster NGC 3293, using ultraviolet spectra obtained by the Hubble Space Te…
The Solar Twin Planet Search. V. Close-in, low-mass planet candidates and evidence of planet accretion in the solar twin HIP 68468
Jorge Melendez, Megan Bedell, Jacob L. Bean +14
[Methods]. We obtained high-precision radial velocities with HARPS on the ESO 3.6 m telescope and determined precise stellar elemental abundances (~0.01 dex) using MIKE spectra on…
The Solar Twin Planet Search. I. Fundamental parameters of the stellar sample
I. Ramirez, J. Melendez, J. Bean +10
We are carrying out a search for planets around a sample of solar twin stars using the HARPS spectrograph. The goal of this project is to exploit the advantage offered by solar twi…
18 Sco: a solar twin rich in refractory and neutron-capture elements. Implications for chemical tagging
J. Melendez, I. Ramirez, A. I. Karakas +12
We study with unprecedented detail the chemical composition and stellar parameters of the solar twin 18 Sco in a strictly differential sense relative to the Sun. Our study is mainl…
