New Precision Orbits of Bright Double-Lined Spectroscopic Binaries. I: RR Lyncis, 12 Bootis, and HR 6169
Jocelyn Tomkin, Francis C. Fekel
Radial velocities from the 2.1 m telescope at McDonald Observatory supplemented with radial velocities from the coude' feed telescope at KPNO provide new precise orbits for the dou…
Orbits of Hyades Multiple-Lined Spectroscopic Binaries. Paper 2: The Double-Lined System HD 27149
Jocelyn Tomkin
A new determination of the orbit of the Hyades double-lined spectroscopic binary HD 27149 is presented. The well-defined orbit provides the spectroscopic basis for an extremely acc…
The Chemical Compositions of Galactic Disk F and G Dwarfs
Bacham E. Reddy, Jocelyn Tomkin, David L. Lambert +1
Photospheric abundances are presented for 27 elements from carbon to europium in 181 F-G dwarfs from a differential LTE analysis of high-resolution and high signal-to-noise spectra…
The rise and fall of the NaMgAl stars
Jocelyn Tomkin, Bengt Edvardsson, David L. Lambert +1
We have made new abundance determinations for a sample of NaMgAl stars. These stars, which are a subgroup of the nearby metal-rich field F and G disk dwarfs, were first identified…
