A Kine-Chemical Investigation of the AB Dor Moving Group "Stream"
Scott A. Barenfeld, Eric J. Bubar, Eric E. Mamajek +1
The AB Dor Moving Group consists of a "nucleus" of ~10 stars at d ~ 20 pc, along with dozens of purported "stream" members distributed across the sky. We perform a chemical and kin…
A Revised Age for Upper Scorpius and The Star-Formation History Among the F-Type Members of the Scorpius-Centaurus OB Association
Mark J. Pecaut, Eric E. Mamajek, Eric J. Bubar
We present an analysis of the ages and star-formation history of the F-type stars in the Upper Scorpius (US), Upper Centaurus-Lupus (UCL) and Lower Centaurus-Crux (LCC) subgroups o…
Lithium in the Upper Centaurus Lupus and Lower Centaurus Crux Subgroups of Scorpius-Centaurus
Eric J. Bubar, Marc Schaeuble, Jeremy R. King +2
We utilize spectroscopically derived model atmosphere parameters and the \ion{Li}{1} subordinate line and the doublet to derive lithium abundances for 1…
V474 Car: A Rare Halo RS CVn Binary in Retrograde Galactic Orbit
Eric J. Bubar, Eric E. Mamajek, Eric L. N. Jensen +1
We report the discovery that the star V474 Car is an extremely active, high velocity halo RS CVn system. The star was originally identified as a possible pre-main sequence star in…
Spectroscopic Abundances and Membership in the Wolf 630 Moving Group
Eric J. Bubar, Jeremy R. King
The concept of kinematic assemblages evolving from dispersed stellar clusters has remained contentious since Eggen's initial formulation of moving groups in the 1960's. With high q…
Keck Hires Spectroscopy of Candidate Post T Tauri Stars
Eric J. Bubar, Jeremy R. King, David R. Soderblom +2
We use high-signal-to-noise (150-450), high resolution () Keck HIRES spectroscopy of 13 candidate post T Tauri stars to derive basic physical parameters, lithi…
