Radial velocities of blue stragglers in M3
Publications of the Astronomical Society of the Pacific, 1983The authors have obtained 1 A resolution spectra of five blue stragglers in M3 all with mv ≥ 17.3 using the MMT spectrograph and photon-counting Reticon. The spectra cover the range 4580 A to 5450 A, and except for Hβ are devoid of strong features. From measurements of the Hβ lines in the five blue stragglers and three velocity standards the authors ...
