Spectroscopic Binary Orbits from Photoelectric Radial Velocities - Paper 191: HD 17310, HD 70645 and HD 80731
R. F. Griffin, H. M. J. Boffin
The three objects have been identified as members of the recently recognized class of Gamma Doradus stars, which exhibit multi-periodic photometric variations that are thought to a…
Spectroscopic Binary Orbits from Photoelectric Radial Velocities -- Paper 171: HD 152028 and Hde 284195 (GK Draconis and V1094 Tauri)
R. F. Griffin, H. M. J. Boffin
The two stars that form the subject of this paper are both short-period double- lined eclipsing binaries having non-circular orbits despite their short periods. Although the HD typ…
Direct Observation of the Fourth Star in the Zeta Cancri System
J. B. Hutchings, R. F. Griffin, F. Menard
Direct imaging of the zeta Cnc system has resolved the fourth star in the system, which is in orbit around zeta Cnc C. The presence of the fourth star has been inferred for many ye…
9 Aurigae: Strong Evidence for Non-Radial Pulsations
Kevin Krisciunas, Roger F. Griffin, Edward F. Guinan +2
We present further photometric observations of the unusual F0 V star 9 Aurigae and present evidence that this star's radial velocity, spectroscopic line widths and line depths are…
