DDO Photometry of M71: Carbon and Nitrogen Patterns Among Evolving Giants
M. M. Briley, G. H. Smith, C. F. Claver
We present V, B-V, and DDO C(41-42) and C(42-45) photometry for a sample of 75 red giants down to M_V = +2 in the relatively metal-rich Galactic globular cluster M71. The C(41-42)…
Calibration of the CH and CN Variations Among Main Sequence Stars in M71 and in M13
Michael M. Briley, Judith G. Cohen
An analysis of the CN and CH band strengths measured in a large sample of M71 and M13 main sequence stars by Cohen (1999a,b) is undertaken using synthetic spectra to quantify the u…
Abundances in Stars from the Red Giant Branch Tip to the Near the Main Sequence in M71: I. Sample Selection, Observing Strategy and Stellar Parameters
Judith G. Cohen, Bradford B. Behr, Michael M. Briley
We present the sample for an abundance analysis of 25 members of M71 with luminosities ranging from the red giant branch tip to the upper main sequence. The spectra are of high dis…
Abundances in Stars from the Red Giant Branch Tip to the Near Main Sequence in M71: II. Iron Abundance
Solange V. Ramirez, Judith G. Cohen, Jeremy Buss +1
We present [Ffe/H] abundance results that involve a sample of stars with a wide range in luminosity from luminous giants to stars near the turnoff in a globular cluster. Our sample…
